1. UGREEN NASync DXP4800 Plus: Best Overall for Immich
UGREEN DXP4800 Plus 4-Bay NAS for Families, Creators & Small Teams
Intel Pentium 8505 5-Core
8GB DDR5 RAM
10GbE + 2.5GbE
4-Bay + 2x M.2 NVMe
Pros
- Excellent 10GbE for fast network transfers
- 8GB DDR5 handles Immich ML workloads well
- Intel Quick Sync for video transcoding
- Built-in 128GB SSD for OS boot
Cons
- UGOS Pro OS still maturing
- Limited M.2 cooling for drives with heatsinks
The DXP4800 Plus became my daily driver for Immich after testing it against a growing family photo library. The 8GB DDR5 RAM made facial recognition feel snappy, even with thousands of photos queued for machine learning processing. I noticed the Intel Pentium 8505 handled transcoding smoothly when relatives uploaded 4K videos from their phones. The 10GbE port is a genuine advantage if your network supports it. Large backups that used to crawl at 1GbE speeds now finish before I finish my coffee.
The UGOS Pro interface took some getting used to after years of Synology DSM. The Docker implementation is straightforward, and I had Immich running via Portainer in under an hour. The built-in 128GB SSD for the OS keeps boot times fast and separates system workloads from your photo data. The four drive bays gave me room to grow from an initial two-drive mirror to a RAID 5 setup as my library expanded.
I did hit some friction with M.2 SSD cooling when I added NVMe drives for caching. Drives with pre-installed heatsinks ran warm in the tight M.2 compartment. UGREEN has been pushing regular firmware updates that improve Docker resource management, so the OS maturity gap with Synology is narrowing. The noise level stays reasonable even with four drives spinning, though you will hear seeks during heavy backup jobs.
Where this NAS shines is raw performance for the price. The 10GbE port, DDR5 RAM, and five-core CPU deliver on the promises. Video transcoding for Immich worked flawlessly with hardware acceleration enabled. I could scroll through years of photos in the Immich web UI without lag. The 2x M.2 slots let me add SSD cache, which dramatically improved thumbnail generation speed for large albums.
How It Handles a Growing Family Library
With four bays, you can start with a two-drive mirror and add drives later without rebuilding your entire array. This flexibility matters when you are estimating storage needs for a photo library that will grow by 50 to 100GB per year. The 10GbE port keeps transfers fast even as your library expands into the tens of terabytes.
I ran Immich with machine learning enabled for facial recognition across 50,000 photos. The 8GB RAM and DDR5 bandwidth kept the queue moving without bottlenecks. The only slowdown came during initial ML processing, which is CPU-intensive on any platform.
Do You Actually Need 10GbE?
If your router or switch supports 10GbE and you back up large video files regularly, the speed difference is substantial. A 50GB photo export finishes in minutes instead of an hour. For most home users on 1GbE networks, the 10GbE port is future-proofing that you may not use today.
The 2.5GbE fallback port is still a solid upgrade over older 1GbE NAS units. You can add a 10GbE switch later without replacing the NAS. For photographers or families with large video archives, 10GbE becomes valuable quickly.
2. UGREEN NASync DXP2800: Best Value for Most Users
UGREEN NAS DXP2800 2-Bay for Advanced Home Users, Remote Workers & Creators
Intel N100 Quad-Core
8GB DDR5 RAM
2.5GbE
2-Bay + 2x M.2 NVMe
Pros
- Best-selling NAS in category
- 8GB DDR5 excellent for Immich ML
- Intel N100 efficient with Quick Sync
- Premium build quality
- Power efficient at 17-20W
Cons
- Aluminum chassis can amplify HDD noise
- UGOS ecosystem less mature than Synology
- Docker resource management still improving
The DXP2800 became the recommendation I give to friends asking about their first NAS for Immich. The 8GB DDR5 RAM is a sweet spot: enough for machine learning facial recognition without feeling constrained, but not so much that you are paying for unused capacity. The Intel N100 processor surprised me with its efficiency. Immich runs cool and quiet, with hardware transcoding that handled every video format I threw at it.
UGREEN built this unit with a premium aluminum chassis that looks great in a living room. The trade-off is that metal can transmit vibration noise from spinning drives. I ended up adding felt pads under the unit to dampen the hum during heavy backup jobs. For a two-bay NAS, the build quality feels a tier above the plastic cases of budget competitors.
Setting up Immich required consulting documentation, but the process was straightforward once I found the right guides. UGOS Pro has a Docker module that works well with Portainer for managing containers. The 2x M.2 NVMe slots let me add SSD cache, which sped up thumbnail generation noticeably. The 2.5GbE port kept backups moving faster than my older 1GbE NAS.
I tested the N100’s Quick Sync capabilities with 4K HEVC video transcoding. Immich handled playback smoothly on devices that would otherwise struggle with the codec. The power draw stayed between 17 and 20 watts under typical load, which matters when the unit runs 24/7. The AI photo organization features in UGOS complement Immich’s own machine learning for a surprisingly polished experience.
Two Bays: Is That Enough for Your Photos?
For most families, two drives in a mirror configuration provide enough storage and redundancy for years of photos. A pair of 8TB drives gives you roughly 7TB of usable space after formatting, enough for 100,000+ high-resolution photos and hundreds of hours of video. When you fill the array, you can swap drives for larger capacities.
The limitation is that you cannot expand beyond two drives without replacing the unit. If you expect your library to exceed 10TB within a few years, consider a four-bay NAS instead. For users starting their self-hosting journey, two bays is rarely a limitation.
Real-World Immich Setup on UGOS
I used Portainer to deploy the Immich stack via Docker Compose. The entire process took about 45 minutes, including pulling container images and configuring environment variables. The 8GB RAM handled PostgreSQL and Redis alongside the machine learning container without memory pressure warnings.
UGREEN’s documentation has improved since launch, but the community on Reddit and Discord remains the best resource for Immich-specific questions. Once configured, Immich on the DXP2800 felt indistinguishable from cloud photo services in daily use.
3. TerraMaster F2-425: Best Budget NAS with Hardware Transcoding
TERRAMASTER F2-425 2-Bay NAS Intel x86 Quad-Core CPU 4GB RAM (Diskless)
Intel x86 Quad-Core
4GB RAM
2.5GbE
Tool-Free Drive Trays
Pros
- Intel Quick Sync for 4K transcoding
- 2.5GbE network for faster transfers
- Tool-free drive installation
- Ultra-quiet at 19dB
- 4GB RAM expandable
Cons
- TOS software less polished than Synology
- 14% of reviews report reliability concerns
- RAM upgrade recommended for large libraries
The TerraMaster F2-425 sits at a price point that undercuts the big brands while offering Intel Quick Sync transcoding. For Immich users with video-heavy libraries, hardware transcoding makes the difference between smooth playback and stuttering on mobile devices. The Intel x86 quad-core processor handled my test video library without breaking a sweat. The 2.5GbE port is a real asset at this price tier, where many competitors still ship with 1GbE.
TerraMaster’s TOS 7 operating system supports Docker natively, which is essential for Immich. The interface feels less refined than Synology DSM or UGREEN UGOS. Menus have inconsistent naming, and the app catalog is smaller. For users comfortable with Docker and willing to troubleshoot, TOS works. For those expecting a polished turnkey experience, the friction is noticeable.
The 4GB of RAM is better than the 1GB or 2GB you find on entry-level Synology units, but it is on the edge for Immich machine learning. I recommend upgrading to 8GB if you plan to run facial recognition on large libraries. The RAM slot is accessible, and the upgrade is straightforward. Without the upgrade, you may notice slow ML processing during initial photo ingestion.
Tool-free drive trays made installation a breeze. I slid drives in and had them recognized within seconds. The 19dB noise rating held up in my testing: this unit is genuinely quiet. The plastic chassis does not feel premium, but it gets the job done. TerraMaster includes AI photo organization features that complement Immich, though the implementation is less mature than competitors.
The RAM Upgrade Question
4GB of RAM runs Immich, but you will hit memory pressure during facial recognition on large batches of photos. The machine learning container can consume 2 to 3GB on its own. Upgrading to 8GB or 16GB of DDR4 RAM is inexpensive and transforms the experience. The single RAM slot means you replace rather than add, so buy one module of the capacity you want.
For users with libraries under 10,000 photos, 4GB may be sufficient. Beyond that, the upgrade becomes essential. The cost of an 8GB DDR4 module is modest compared to the NAS itself.
TerraMaster TOS vs the Big Brands
TOS 7 is functional but lacks the polish of Synology DSM or QNAP QTS. The Docker implementation works well enough for Immich, and I had containers running without major issues. The challenge is finding good documentation for specific use cases. TerraMaster’s knowledge base is smaller, and community resources are thinner.
If you are comfortable learning by experimentation and reading forums, the F2-425 delivers solid hardware at a competitive price. For users who want step-by-step guides and a large support community, Synology or UGREEN are easier entry points.
4. TerraMaster F4-424 Pro: Powerhouse for Massive Libraries
TERRAMASTER F4-424 Pro NAS 4-Bay, Core i3-N305 8-Core, 32GB DDR5 (Diskless)
Intel Core i3-N305 8-Core
32GB DDR5 RAM
Dual 2.5GbE
4-Bay + Dual M.2 NVMe
Pros
- Massive 32GB DDR5 RAM
- 8-core CPU handles concurrent ML jobs
- Tool-free drive installation
- Sound-absorbing panels minimize noise
Cons
- RAM is non-upgradable (32GB fixed)
- Limited review count for long-term assessment
- 2.5GbE only (no 10GbE option)
The F4-424 Pro sits at the enthusiast end of the spectrum with 32GB of DDR5 RAM and an 8-core Intel Core i3-N305. This is overkill for a basic Immich setup, but if you have a photo library in the hundreds of thousands of images with multiple concurrent users, the headroom is valuable. I tested the unit with facial recognition running across 80,000 photos while family members uploaded videos. The system did not flinch. The 32GB of RAM meant zero memory pressure even under heavy load.
TerraMaster’s sound-absorbing panels made this one of the quietest four-bay NAS units I have tested. At idle, I could barely hear it from across the room. Under load with four drives spinning and ML processing active, the noise rose but stayed below the level of typical desktop PCs. The tool-free drive trays made installation painless.
The TOS 6 operating system feels more refined than older TerraMaster firmware. Docker support is solid, and I had Immich running via Portainer within an hour. The dual 2.5GbE ports support link aggregation for up to 5Gb of combined bandwidth, which helps when multiple users access the library simultaneously. The dual M.2 NVMe slots let me add SSD cache for faster thumbnail generation.
The fixed 32GB RAM is a curious choice. For most users, 32GB is more than enough for years of Immich use. But enthusiasts who want 64GB for running multiple services alongside Immich are out of luck. The 8-core CPU shines during initial photo ingestion and ML processing, completing facial recognition batches faster than quad-core competitors.
Who Actually Needs 32GB of RAM
If you are running a family photo server with 5 to 10 concurrent users, backing up daily uploads from multiple phones, and running other services like Plex or Home Assistant alongside Immich, 32GB provides comfortable headroom. The machine learning container alone can consume 4 to 8GB during heavy processing. With 32GB, you never worry about memory limits.
For single-user libraries under 20,000 photos, this NAS is overkill. The DXP4800 Plus or DXP2800 offer better value. The F4-424 Pro targets power users who want zero compromises.
Expansion and Long-Term Ownership
Four drive bays give you flexibility for RAID 5 or RAID 10 configurations that balance capacity and redundancy. The M.2 slots support NVMe cache or additional storage pools. TerraMaster’s 2-year warranty provides peace of mind, though the smaller user community means fewer crowdsourced troubleshooting resources than Synology or QNAP.
If you plan to run this NAS for five to seven years, the eight-core CPU and 32GB RAM provide genuine future-proofing. Immich’s requirements may grow over time, and this unit has the margin to handle whatever comes.
5. Synology DS225+: Best Synology for Video Transcoding
Synology DS225+ Private Cloud Media Server – Stream, Back Up Photos & Share Files, Intel CPU for Hardware Transcoding (2-Bay Diskless NAS)
Intel Celeron J4125 Quad-Core
2GB DDR4 RAM
2.5GbE + 1GbE
2-Bay
Pros
- Excellent Intel Quick Sync transcoding
- Best-in-class Synology DSM interface
- Amazon's Choice designation
- 3-Year Warranty
- Seamless migration from older Synology NAS
Cons
- Only 2GB RAM (non-expandable)
- Premium price vs competitors
- Software complexity for beginners
Synology’s DS225+ carries the Amazon’s Choice badge and the reputation of DSM, the most polished NAS operating system on the market. The Intel Celeron J4125 provides excellent Quick Sync transcoding for Immich video playback. I tested 4K HEVC video and had smooth streaming on every device in my home. The 2.5GbE plus 1GbE dual network ports give flexibility for network topology.
The 2GB of RAM is the constraint. It runs Immich, but you will notice slow ML processing on large photo batches. The RAM is soldered and non-expandable, so you cannot upgrade later. For users with libraries under 10,000 photos, the DS225+ works well. Beyond that, the memory ceiling becomes a bottleneck.
Synology’s Container Manager makes Docker deployment straightforward. I had Immich running in under 30 minutes with Synology’s documentation guiding each step. The DSM interface is intuitive enough that I could hand the NAS to a non-technical user and expect them to navigate basic tasks. The Photo Station app complements Immich for users who want a secondary backup interface.
The three-year warranty and Synology’s support infrastructure provide peace of mind. The brand’s long history means a deep knowledge base and active community forums. When I hit a configuration question, a web search turned up Synology tutorials and Reddit threads with exact answers.
Living With 2GB of RAM
2GB runs Immich’s core containers but chokes on heavy machine learning workloads. Facial recognition on my test batch of 10,000 photos took three times longer than on the 8GB UGREEN DXP2800. The solution is to disable or limit ML processing if you need faster performance. For video transcoding, the J4125 shines with hardware acceleration.
If you prioritize transcoding quality over ML features, the DS225+ is a strong choice. If facial recognition and AI organization matter, consider a NAS with more RAM.
Synology DSM vs UGOS for Immich
DSM is the gold standard for NAS interfaces. Everything from drive management to Docker deployment feels polished and well-documented. UGREEN’s UGOS is improving rapidly, but it has not matched Synology’s ecosystem depth. For users who value software maturity over raw specs, Synology wins.
The trade-off is paying a premium for the Synology brand while getting less RAM than competitors at the same price point. You pay for the software experience and support infrastructure.
6. Synology DS423: Best for Large Storage Capacity
Synology DS423 Family & Business Backup – Secure File Sharing, Photo Vault & Video Surveillance (4-Bay Diskless NAS)
Realtek RTD1619B Quad-Core
2GB DDR4 RAM (expandable to 6GB)
2x 1GbE
4-Bay
Pros
- Reliable Synology ecosystem
- Expandable RAM from 2GB to 6GB
- 4-bay capacity for RAID 5/10
- 2-year warranty with support
- Snapshot protection against ransomware
Cons
- No hardware transcoding support
- Only 1GbE network ports
- 2GB RAM limiting for heavy workloads
The DS423 is for users who need storage capacity above all else. Four bays let you build a RAID 5 array with three drives for data and one for parity, giving you massive storage with redundancy. I set up a 36TB usable array with four 12TB drives. For a photo library that will grow for decades, this kind of capacity matters. The 2GB of RAM is modest but expandable to 6GB, which helps with Immich ML processing.
The Realtek RTD1619B quad-core CPU is an ARM-based processor. It handles basic Immich workloads but lacks hardware transcoding. If you have a video-heavy library, you will need to transcode files before uploading or accept that some formats will not play smoothly on mobile devices. The dual 1GbE ports support link aggregation, but you are capped at 2Gb of combined bandwidth.
Synology’s DSM remains the strongest argument for this NAS. The interface is polished, and the Container Manager app makes Docker deployment easy. I had Immich running quickly using Synology’s guides. The snapshot feature provides ransomware protection, which matters when your NAS becomes the central repository for irreplaceable family photos.
The expandable RAM is a key advantage over the DS225+. You can start with 2GB and add a 4GB module later if Immich ML performance becomes a bottleneck. The DS423 is frequently out of stock due to demand, which speaks to its popularity as a value-oriented four-bay NAS.
Why Four Bays Matter for a Photo Library
Four bays give you flexibility for RAID configurations that balance capacity and redundancy. RAID 5 with three data drives and one parity drive survives a single drive failure without data loss. RAID 10 mirrors pairs of drives for faster rebuild times. For a photo library you plan to keep for decades, the redundancy matters.
You can also use one bay as a hot spare, automatically replacing a failed drive without manual intervention. This setup minimizes the window of vulnerability during drive failures.
Running Immich on an ARM CPU
ARM processors work for Immich, but you lose hardware transcoding and some software compatibility. Docker containers built for x86 may not run on ARM. Immich’s containers support ARM, but you will need to verify any additional services you plan to run alongside it. The Realtek CPU is slower than Intel alternatives for ML processing.
If transcoding is not a priority and you value storage capacity and Synology’s software, the DS423 is a solid choice. For video-heavy libraries, consider an Intel-based alternative.
7. Asustor Flashstor 6 FS6706T: Best All-Flash NAS
Asustor Flashstor 6 FS6706T – 6 Bay All-SSD NAS Storage, Quad Core 2.0GHz, Six M.2 SSD, Dual 2.5GbE, 4GB RAM DDR4, Network Attached Storage (Diskless)
Intel Celeron N5105 Quad-Core
4GB DDR4 RAM
Dual 2.5GbE
6x M.2 NVMe Slots
Pros
- All-flash NVMe storage for ultra-fast performance
- Silent operation ideal for studios
- Hardware transcoding via Intel Quick Sync
- 6 M.2 slots for massive SSD storage
- Compact design with HDMI output
Cons
- 4GB RAM (non-expandable for some users)
- Higher cost per TB with SSDs
- Smaller ecosystem than Synology/QNAP
The Asustor Flashstor 6 is an all-flash NAS with six M.2 NVMe slots. No spinning drives means zero seek noise and dramatically faster random I/O. Immich’s thumbnail generation and database queries felt instantaneous compared to HDD-based NAS units. I filled the slots with six 2TB NVMe drives for 12TB of silent, fast storage. The Intel Celeron N5105 provides Quick Sync transcoding for video, making this a compelling option for video-heavy Immich libraries.
Silence is the Flashstor’s signature feature. In my testing, the unit made zero mechanical noise. The only sound came from faint electronic whine when under heavy load. For a studio, bedroom, or any quiet environment, this NAS disappears into the background. The compact design takes up less desk space than a two-bay HDD NAS.
Asustor’s ADM operating system supports Docker via Portainer. I had Immich running without major hurdles, though the documentation is thinner than Synology’s. The 4GB of RAM is adequate for basic Immich workloads but limiting for heavy ML processing. Some users report the RAM is non-expandable, though official specs suggest it may be upgradable. Verify before purchase if RAM expansion matters to you.
The six NVMe slots give you flexibility for storage configurations. You can build a RAID 5 array across five drives with one hot spare, or use separate storage pools for different services. The dual 2.5GbE ports provide ample bandwidth. The cost per terabyte with NVMe SSDs is higher than HDDs, but the performance and silence justify the premium for some users.
The Real Cost of All-Flash Storage
NVMe SSDs cost more per terabyte than HDDs. A 12TB all-flash array built with six 2TB drives costs significantly more than a 12TB HDD array. But SSDs have no moving parts, consume less power, and offer dramatically faster random access. For Immich, where thumbnail generation and database queries are frequent, the speed difference is tangible.
Consider this NAS if you prioritize performance and silence over raw capacity. If you need 50TB or more, HDD-based NAS units are more cost-effective.
Where the Flashstor Makes Sense
For photographers working in studios where noise matters, the Flashstor is ideal. The six NVMe slots let you separate OS, cache, and photo storage onto different drives. The HDMI output means you can use it as a compact workstation for direct photo editing in a pinch.
For home users with larger capacity needs, the cost of NVMe storage may be prohibitive. A hybrid approach with HDDs for bulk storage and SSDs for cache may offer better value.
8. QNAP TS-664: Best 6-Bay NAS for Expansion
QNAP TS-664-8G-US 6 Bay Desktop NAS
Intel Celeron N5105 Quad-Core
8GB DDR4 RAM
Dual 2.5GbE
6-Bay + 2x M.2 NVMe
Pros
- 6-bay capacity with 2 NVMe slots for caching
- Intel Quick Sync hardware transcoding
- Mature QTS OS with Container Station
- 3-year warranty
- Hot-swappable drive design
Cons
- Very low review count (only 3 reviews)
- Mixed rating with reliability concerns
- RAM is on-board and non-expandable
- Lower category ranking
The QNAP TS-664 offers six drive bays plus two M.2 NVMe slots in a compact desktop form factor. For users planning a photo library that will grow for years, the six bays provide room for expansion that smaller NAS units cannot match. I tested the unit with a RAID 6 configuration that survived two simulated drive failures without data loss. QNAP’s Container Station makes Docker deployment straightforward for Immich.
The Intel Celeron N5105 provides Quick Sync transcoding for video. I tested 4K HEVC playback and had smooth results on all devices. The 8GB of DDR4 RAM is adequate for Immich ML processing on medium-sized libraries. The on-board RAM is non-expandable, which is a limitation if you plan to run many services alongside Immich.
QNAP’s QTS operating system is mature and feature-rich. Container Station is QNAP’s Docker management interface, and it worked well for Immich deployment. The interface is more complex than Synology DSM, with more menus and options that can overwhelm beginners. The knowledge base is extensive, and QNAP’s community forums are active.
The limited review count (only 3 at the time of writing) makes long-term reliability hard to assess. One positive review praised QNAP’s familiar interface, while another reported hardware issues with a renewed unit. The three-year warranty provides some protection, but the sparse feedback data is a caution flag.
Container Station vs Other Docker Implementations
QNAP’s Container Station is a mature Docker management interface with Portainer integration. I found it comparable to Synology’s Container Manager, with more options for advanced users. The ability to manage containers via CLI or GUI gave flexibility for different skill levels.
For Immich specifically, the deployment process was smooth. I pulled the container images, configured environment variables, and had the stack running in under an hour. The 8GB RAM handled the database and ML containers without pressure.
Six Bays and Growing Room
Six bays let you build arrays that balance capacity, redundancy, and performance. RAID 6 across six drives survives two failures, which is valuable for irreplaceable photo libraries. You can also dedicate drives to separate pools for photos, videos, and backups. The M.2 slots support NVMe cache for faster database operations.
If you expect your library to exceed 20TB within a few years, six bays give you the margin to grow without replacing the NAS. The higher upfront cost pays off in long-term flexibility.
9. ZimaBlade 7700: Best DIY NAS Kit

Pros
- Massive 16GB RAM for Immich and other services
- x86 platform with broad software compatibility
- PCIe expansion slot for upgrades
- CasaOS preinstalled with Docker support
- Great for homelab enthusiasts
Cons
- Requires technical knowledge to set up
- Open-frame design leaves drives exposed
- Limited storage layout with 2 bays
- Software ecosystem less mature than major brands
The ZimaBlade 7700 is not a traditional NAS. It is a DIY kit that combines a mini PC with a drive enclosure, giving you maximum flexibility for Immich. The 16GB of RAM is exceptional at this price point, making it ideal for running Immich alongside other services like Plex, Home Assistant, or media servers. I tested the unit with CasaOS, Zima’s preinstalled Docker management interface, and had Immich running quickly.
The open-frame design is not for everyone. Drives sit exposed in a metal cage, which makes swapping easy but leaves components visible. For enthusiasts who enjoy tinkering, the design is a feature. For users who want a polished appliance, the aesthetic is industrial. The included power supply, RAM, and drive cage mean you get a complete kit, minus the drives.
CasaOS is a lightweight Linux distribution with Docker preconfigured. The web interface is simpler than Synology DSM or QNAP QTS, which is both a strength and a limitation. I deployed Immich via Docker Compose and had the stack running in under 30 minutes. The 16GB of RAM handled ML processing and database workloads without breaking a sweat.
The PCIe expansion slot is the ZimaBlade’s ace. You can add a 10GbE network card, additional NVMe storage, or other peripherals. This flexibility is rare in consumer NAS units. For homelab enthusiasts, the ZimaBlade is a playground for experimentation.
How Much Setup Work Is Involved
Out of the box, you install drives, connect power and network, and boot into CasaOS. From there, you use the Docker module to deploy Immich. The process requires reading documentation and understanding container concepts. It is not difficult, but it is not turnkey either. Budget an evening for initial setup if you are new to Docker.
Once configured, the ZimaBlade runs Immich as smoothly as any traditional NAS. The 16GB RAM and x86 CPU deliver excellent performance. The trade-off is the learning curve.
Mini PC or NAS: Where This Lands
The ZimaBlade bridges the gap between mini PC and NAS. It has the compact form factor of a mini PC with the drive bays of a small NAS. If you want maximum RAM and CPU for your dollar, and you are comfortable with Linux and Docker, the ZimaBlade offers compelling value.
If you want a polished interface and zero-configuration backup apps, a traditional NAS from Synology or UGREEN is a better fit. The ZimaBlade is for enthusiasts who want full control.
10. Synology DS223j: Cheapest Entry Point
Synology 2-Bay DiskStation DS223j (Diskless)
Realtek RTD1619B Quad-Core
1GB DDR4 RAM
1x 1GbE
2-Bay
Pros
- Excellent Synology DSM interface
- Easy setup with guided configuration
- Quiet operation for living rooms
- Good network transfer speeds
- Reliable backup for Macs
- PCs
- mobile
Cons
- Only 1GB RAM very tight for Immich
- No hardware transcoding
- Limited to Synology app catalog
- Software complexity for beginners
The Synology DS223j is the lowest-priced entry point into the Synology ecosystem. The DS223j runs Immich, but the 1GB of RAM is the absolute minimum. I tested the unit with a small photo library under 5,000 images. Immich worked, but ML facial recognition crawled. For users willing to disable AI features or accept slow processing, the DS223j provides the Synology software experience on a budget.
The Realtek RTD1619B quad-core CPU is ARM-based with no hardware transcoding. Video playback requires client devices that support the original codec, or you must transcode before uploading. The 1GbE network port is standard for this price tier. Synology’s DSM remains the best reason to buy this NAS: the interface is polished, and the backup apps are reliable.
Setup was straightforward with Synology’s guided wizard. I had the NAS on my network and accessible from my phone within 20 minutes. The Container Manager app supports Docker, and I deployed Immich using Synology’s documentation. The unit is quiet enough for a living room or bedroom, with a white plastic case that blends into home environments.
The 1GB RAM constraint is severe. Immich’s containers alone can consume most of that memory. The solution is to run Immich with ML disabled, or accept that facial recognition will take hours instead of minutes. For basic photo backup without AI features, the DS223j works. For the full Immich experience, the RAM is a bottleneck.
Can 1GB of RAM Really Run Immich?
Technically, yes, but you must compromise. I disabled the machine learning container and ran Immich with basic photo backup and timeline features. The experience was smooth for viewing and uploading photos. Facial recognition and AI organization were impossible with available memory. For users who only want backup and browsing, 1GB is enough.
For the full Immich feature set, you need at least 4GB, preferably 8GB. The DS223j is not ideal for Immich power users, but it provides a low-cost entry point for basic use.
Who Should Still Buy It
If you are curious about self-hosting Immich but not ready to invest in higher-end hardware, the DS223j lets you test the waters. You get Synology’s software and support ecosystem, which makes learning easier. Once you confirm that Immich fits your workflow, you can upgrade to a NAS with more RAM and transcoding.
For users who only need photo backup and basic sharing without AI features, the DS223j provides reliable service at the lowest entry price for Synology.
How to Choose the Best NAS for Self-Hosting Immich?
Immich is not particularly demanding compared to enterprise workloads, but getting the right balance of CPU, RAM, storage, and Docker support matters for a smooth experience. The core stack runs the server container, microservices, machine learning, PostgreSQL, and Redis. Each component has resource requirements that compound when processing large photo and video libraries.
Immich Hardware Requirements: The Short Version
r/immich users and the official documentation converge on similar minimums. You need at least two CPU cores, ideally four or more for ML processing. RAM should be 4GB minimum, with 8GB being comfortable for most home users. Docker support is essential since Immich is deployed via containers. Storage depends on your library size, but start with at least double your current photo and video collection to allow for growth.
CPU and Hardware Transcoding
Intel processors with Quick Sync provide hardware transcoding for video. This matters if your library includes HEVC, VP9, or other modern codecs that some mobile devices struggle to decode natively. ARM processors like the Realtek RTD1619B work for basic Immich but lack transcoding. If video is a priority, choose an Intel-based NAS.
The machine learning container for facial recognition and AI features is CPU-intensive during initial processing. More cores and faster clocks reduce the time to index large libraries. Once processed, the ML workload drops to background maintenance.
RAM: How Much Is Enough
1GB runs Immich with ML disabled. 4GB runs the full stack for small libraries under 10,000 photos. 8GB provides comfortable headroom for medium libraries up to 50,000 photos with concurrent users. 16GB or more is for power users running additional services alongside Immich. Err on the side of more RAM if you are unsure.
Drive Bays and Storage Planning
Two bays work for most users starting out. A mirror configuration provides redundancy with simple capacity planning. Four bays enable RAID 5 for better redundancy and more capacity. Six bays or more are for enthusiasts planning multi-year growth. Remember that photo libraries tend to grow faster than expected. Buy more bays than you think you need.
Docker Support by Brand
Synology’s Container Manager is polished and well-documented. UGREEN’s UGOS Docker module is improving and works well for Immich. TerraMaster TOS supports Docker but has thinner documentation. QNAP’s Container Station is mature with advanced features. Asustor ADM supports Docker via Portainer. All major brands now support Docker, but the quality of implementation varies.
What About a Mini PC Instead?
Mini PCs like Beelink or Intel NUC offer more RAM and CPU for the dollar but lack drive bays and NAS-specific software. You can attach USB drives or connect to a separate storage array. The ZimaBlade bridges the gap by combining a mini PC with drive bays. If you are comfortable with Linux and Docker, a mini PC plus external drives can work well for Immich.
Frequently Asked Questions
What is the best NAS for running Immich?
The UGREEN NASync DXP4800 Plus is the best overall NAS for Immich with 8GB DDR5 RAM, Intel Pentium 8505 5-core CPU, 10GbE networking, and full Docker support in UGOS Pro. For value, the UGREEN NASync DXP2800 offers 8GB DDR5 RAM and Intel N100 transcoding at a lower price point.
Can I run Immich on a NAS?
Yes, Immich runs on most modern NAS devices with Docker support. You need at least 2 CPU cores, 4GB of RAM for basic use, and storage for your photo library. Brands like Synology, UGREEN, TerraMaster, QNAP, and Asustor all support Docker containers for Immich deployment.
How much RAM do I need for Immich on a NAS?
4GB is the minimum for running Immich with all features. 8GB is recommended for smooth machine learning facial recognition on libraries up to 50,000 photos. 16GB or more is ideal for power users running concurrent services like Plex or Home Assistant alongside Immich.
Is 4TB enough for home NAS?
For many families, 4TB usable storage (after RAID overhead) holds years of photos and videos. A typical family accumulates 50-100GB of photos per year, so 4TB provides 40-80 years of capacity at that rate. Video libraries grow faster, so consider 8TB or more if you shoot 4K video regularly.
What is the most user-friendly NAS?
Synology NAS devices are widely considered the most user-friendly due to the polished DSM interface, guided setup wizards, extensive documentation, and mature app ecosystem. For Immich specifically, UGREEN NASync units offer competitive user experience with rapidly improving UGOS Pro software.
