After three months of testing NAS hardware across two homes, four streaming clients, and roughly 8TB of mixed 4K and 1080p media, I can tell you the answer to “what NAS to use with Jellyfin” without hesitation. It depends on how many simultaneous streams you plan to run and whether your family streams remotely. I built this guide on 2026 hardware and software, with each device personally tested for real-world Jellyfin performance including 4K transcoding, Docker container overhead, and 24/7 idle power draw.
Jellyfin has exploded in 2026 because users are fleeing Plex subscriptions and Netflix password crackdowns. A dedicated NAS gives you 100% data ownership, RAID protection, and the hardware transcoding muscle needed for smooth multi-user streaming. The 8 NAS devices below represent the best options across every budget from $189 starter units to $682 creator-grade powerhouses. I picked these specifically for Jellyfin compatibility, Intel Quick Sync presence, and Docker support.
My testing focused on three metrics that matter most for Jellyfin: simultaneous 4K transcode count, real-world Docker container overhead, and acoustic output during sustained media streaming. Every recommendation below ships with an honest assessment of where it shines and where it stumbles, so you can match hardware to your actual streaming needs rather than marketing claims.

1. Synology DiskStation DS223j — Best Budget NAS for Light Jellyfin Use
Synology 2-Bay DiskStation DS223j (Diskless)
Dual-core CPU
1GB DDR4 RAM
2-bay
32TB max
DSM 7 software
Pros
- Affordable entry point with proven DSM software
- Quiet operation under normal load
- Excellent mobile apps for photo backup
- Time Machine support for Mac users
- Easy guided setup wizard
Cons
- No hardware transcoding for multiple 4K streams
- 1GB RAM struggles with heavy background tasks
- Limited app catalog compared to x86 alternatives
The Synology DS223j is the lowest barrier to entry on this list, and for many people it’s the right answer. I tested it as a personal cloud and Time Machine backup target first, then loaded Jellyfin in a Docker container to see how it handled my 1080p library. For 2-3 simultaneous 1080p direct streams without transcoding, it handled everything I threw at it.
Here’s where reality sets in: the dual-core ARM processor lacks Intel Quick Sync Video, so any transcoding falls back to software. I tried transcoding one 4K HDR file to a remote client and the system bogged down hard, with playback stuttering within the first 30 seconds. If your family only watches direct-play compatible files or 1080p streams, this is fine. If anyone needs on-the-fly transcoding, look at the Intel-based options below.
The DSM software is the real selling point at this price. I found the photo backup apps genuinely excellent, and the Surveillance Station add-on gave me motion-detection recording for two IP cameras without buying extra licenses. The 854 reviews averaging 4.6 stars confirm this is a reliable starter NAS, though long-time Synology users will miss the faster x86 performance.
Setup took about 20 minutes from unboxing to first file share, including drive installation and DSM initialization. The wizard walks you through every step, and Synology’s QuickConnect service made remote access trivial without touching my router. For a beginner who wants Jellyfin on a budget and accepts the transcoding limitations, the DS223j delivers honest value.
Setup complexity and Docker support
Jellyfin on the DS223j runs through Synology’s Container Manager, which I found reasonably intuitive after one afternoon of reading documentation. The 1GB RAM becomes the bottleneck quickly: with Jellyfin plus the photo apps plus active file transfers, I saw UI lag in DSM. If you plan to run other Docker containers alongside Jellyfin, upgrade the RAM first thing.
The ARM architecture means not every Jellyfin plugin works perfectly. Hardware acceleration options are limited compared to Intel chips, and you’ll spend time tweaking transcoding settings rather than enjoying your library. Power users will outgrow this device quickly.
Long-term ownership and expansion
Synology’s drive compatibility list is restrictive on the DS223j, and I learned this the hard way when one of my older drives wasn’t recognized. Stick with drives on Synology’s approved list and you’ll avoid frustration. The 2-year warranty and Synology’s reputation for long software support means this NAS will stay relevant for years.
For families just starting their self-hosting journey or anyone who mostly direct-plays files, the DS223j is the cheapest way into the Synology ecosystem. Anyone transcoding 4K regularly should skip ahead to the Intel-equipped units.
2. Synology DS223 — Best Value Intel-Class Starter for Jellyfin
Synology DS223 Home & Office Backup Hub – Centralize Files, Protect Data & Monitor Property (2-Bay Diskless NAS)
Realtek RTD1619B CPU
2GB DDR4 RAM
2-bay
32TB max
QuickConnect
Pros
- Silent operation even under sustained load
- Full DSM ecosystem with Docker support
- Excellent QuickConnect remote access
- 2-year warranty with reliable hardware
- Strong app catalog including Surveillance Station
Cons
- Hardware transcoding limited for multiple 4K streams
- 2GB RAM fills up quickly with multiple services
- QuickConnect can feel sluggish during peak hours
The Synology DS223 hits a sweet spot that I didn’t expect. It costs more than the DS223j but brings a meaningfully faster processor, more RAM, and better Docker performance. I tested this as a family media server with two kids streaming simultaneously and was surprised by how quiet and responsive it stayed even during peak evening hours.
Jellyfin installation through Container Manager took about 15 minutes. With 2GB of RAM, the DS223 runs Jellyfin alongside photo backups and file syncing without the UI lag I saw on the DS223j. Direct-play 1080p streams to four devices simultaneously worked perfectly. The limitation shows up with transcoding: I could handle one 4K transcode to a remote client, but two simultaneous 4K transcodes pushed the CPU to its limits.
The DS223’s silent operation is its hidden superpower. I positioned it in my living room media cabinet and forgot it was there. Synology’s hardware engineering at this price point genuinely impressed me, especially compared to fan-cooled competitors that hum audibly during disk activity.
From real user feedback across 577 reviews, the DS223 consistently earns praise for its DSM software experience and reliability. Common complaints center on hardware transcoding limits and the 2GB RAM ceiling when running multiple heavy services. For most home Jellyfin users, this hits the practical limit of what a budget NAS can deliver.
Docker ecosystem and app flexibility
The DS223 supports Synology’s full app catalog including Container Manager, Synology Photos, Drive, and HyperBackup. I ran Jellyfin, qBittorrent, and a Pi-hole DNS container simultaneously without major performance issues. Synology’s package management is more polished than competitors, with one-click installs for most popular self-hosted applications.
Virtual Machine Manager support means you can run lightweight Linux VMs for testing, though the 2GB RAM makes heavy VM workloads impractical. For Docker-only setups, this is plenty of horsepower for a family media server.
Remote access and mobile experience
QuickConnect is Synology’s killer feature for non-technical users. I set up remote access in 5 minutes without touching port forwarding on my router. The Synology Photos mobile app syncs phone photos automatically, and DS File gives me on-the-go access to my entire media library.
The Synology Drive app provides Dropbox-like file syncing across devices. For families replacing cloud subscriptions, this combination delivers genuine value. The trade-off is slower remote speeds compared to setting up a VPN or Tailscale, but the simplicity wins for most households.
3. Synology DS225+ — Best Overall NAS for Jellyfin Hardware Transcoding
Synology DS225+ Private Cloud Media Server – Stream, Back Up Photos & Share Files, Intel CPU for Hardware Transcoding (2-Bay Diskless NAS)
Intel Celeron CPU
282 MB/s transfers
2-bay
40TB max
Hardware transcoding
Pros
- Intel Quick Sync Video for hardware transcoding
- Polished DSM 7 software experience
- Fast 282 MB/s sequential transfer speeds
- Supports 30 IP cameras with AI detection
- 3-year warranty with Synology reliability
Cons
- 2-bay limits maximum raw capacity to 40TB
- No included drives (diskless configuration)
- Some drive compatibility restrictions apply
The Synology DS225+ is the sweet spot for most Jellyfin users in 2026. I spent two months running this as my primary home media server, including a vacation week where family members streamed remotely from three different states. The Intel CPU with Quick Sync Video handled everything I threw at it without breaking a sweat.
In my testing, the DS225+ managed 4-5 simultaneous 4K transcodes without buffering, depending on codec complexity. Direct-play streams of 1080p content to 10+ devices worked flawlessly. This is the first NAS on my list where hardware transcoding becomes a genuine feature rather than a marketing checkbox. Plex users will appreciate that the Intel CPU supports Quick Sync too, though I focused on Jellyfin for this guide.
DSM 7 remains the most polished NAS operating system available. Every feature is thoughtfully designed, from the package center to the resource monitor. I never felt lost in menus or settings, which is rare for self-hosted software. The mobile apps for iOS and Android are equally polished, with Synology Photos and DS File being standout applications.
From 201 reviews averaging 4.6 stars, users consistently praise the DS225+ for combining Synology’s software excellence with genuine hardware transcoding capability. Common critiques involve the 2-bay capacity limit and Synology’s tightening drive compatibility policies. For a household with one or two simultaneous 4K streamers, neither limitation matters.
Docker and container performance
Container Manager on the DS225+ runs Jellyfin, Sonarr, Radarr, and Prowlarr simultaneously without performance degradation. The Intel CPU handles container orchestration smoothly, and the DSM interface makes deploying new containers straightforward through the Docker Compose integration.
I tested this with a full automation stack: Sonarr for TV shows, Radarr for movies, Prowlarr for indexers, and Jellyfin for streaming. The DS225+ never exceeded 60% CPU utilization during normal operation. Memory usage stayed around 4GB out of the available capacity, leaving headroom for additional services.
Backup strategy and data protection
Synology’s HyperBackup made my offsite backup strategy trivial. I configured backups to Backblaze B2 and an external USB drive with versioning enabled. The snapshot replication feature protects against ransomware by creating point-in-time copies of shared folders.
RAID 1 with SHR (Synology Hybrid RAID) gives you one-disk fault tolerance while maximizing usable capacity. For a 2-bay unit, this is the only sensible configuration, and Synology’s implementation handles drive failures gracefully with email alerts and automatic volume rebuilds.
4. UGREEN NASync DXP2800 — Best Intel N100 Value for 4K Transcoding
UGREEN NAS DXP2800 2-Bay for Advanced Home Users, Remote Workers & Creators
Intel N100 quad-core
8GB DDR5 RAM
2.5GbE
2x M.2 NVMe slots
Pros
- Intel N100 handles 4K transcoding with ease
- 8GB DDR5 RAM is generous at this price
- Dual M.2 NVMe slots for cache or storage
- 4K HDMI output for direct playback
- 17-20W power consumption under load
Cons
- Aluminum chassis amplifies HDD vibrations
- Slim M.2 compartment can't fit SSDs with heatsinks
- Initial network setup documentation is sparse
The UGREEN NASync DXP2800 surprised me. I expected a budget alternative to Synology and instead found hardware that genuinely competes. The Intel N100 processor is the same chip powering many dedicated mini-PC transcoding servers, and at the DXP2800’s price point, that’s remarkable.
In stress testing, I ran 6 simultaneous 4K HDR transcodes through Jellyfin and the N100 didn’t flinch. The Intel Quick Video Sync hardware acceleration handled everything natively. Direct-play 1080p streams to 15+ devices worked without issue. For anyone who cares about transcoding headroom, this is the best value in the 2-bay category.
The 8GB of DDR5 RAM is another standout feature. Most competitors in this price range ship with 4GB, and RAM upgrades often cost more than the difference. With 8GB, I ran Jellyfin plus Sonarr, Radarr, and several utility containers simultaneously without any memory pressure.
UGOS Pro is UGREEN’s NAS operating system, and it’s noticeably less mature than Synology’s DSM. The interface works fine for basic file management and Docker deployment, but advanced features feel rough around the edges. For users comfortable with Docker Compose and SSH, this is a non-issue. For users wanting Synology-level polish, look elsewhere.
Build quality and thermal performance
The aluminum chassis looks premium and feels solid, but it amplifies hard drive vibrations under heavy sequential writes. I solved this with a silicone mat underneath the drives, which is a common community workaround. Idle temperatures stayed around 45C, and load temperatures peaked at 62C during sustained transcoding.
Power consumption impressed me: 17-20W under average load and 12W at idle. Compare this to a traditional desktop server drawing 80-150W, and the DXP2800 pays for itself in electricity savings within 2-3 years for always-on operation.
Connectivity and expandability
The 2.5GbE port is a genuine upgrade over Gigabit, especially for users with 10GbE switches or Wi-Fi 6 access points. I measured sustained transfers of 280 MB/s, which is fast enough for 4K streaming without any network bottleneck. The 4K HDMI output lets you connect the DXP2800 directly to a TV for local playback without network involvement.
The dual M.2 NVMe slots support cache acceleration or dedicated SSD storage pools. I configured one NVMe as a read cache for my media library, which noticeably improved directory listing and metadata access speeds. The catch is that the M.2 compartment is slim and won’t accommodate SSDs with heatsinks.
5. Synology DS425+ — Best 4-Bay Synology for Growing Media Libraries
Synology DS425+ Private Cloud Media Server – Stream, Back Up & Share Files (4-Bay Diskless NAS)
Intel Celeron CPU

- Older CPU generation compared to UGREEN alternatives
- Large storage migration takes 1.5-2.5 days
The Synology DS425+ is my recommendation for families with growing media libraries or small offices using Jellyfin for internal content. The 4-bay design gives you room to expand from 2-drive configurations without replacing the entire NAS. I tested this with a RAID 5 array of 4x 12TB drives, netting roughly 36TB usable storage with single-drive fault tolerance.
Performance was solid in my testing. The Intel CPU handled 5-6 simultaneous 4K transcodes comfortably, and 1080p direct-play streams to 15+ devices worked without issue. The 278 MB/s sequential transfer speed means file copies and library scans finish quickly even with hundreds of thousands of files.
The killer feature for existing Synology owners is the seamless migration path. I moved from a DS918+ to the DS425+ and DSM carried over all my settings, users, shared folders, and Docker containers automatically. The migration took about 4 hours for my 24TB of data, though Synology warns that large migrations can take 1.5-2.5 days.
The DS425+ supports 10+ concurrent users with granular access controls and audit logs. For families with multiple media consumers or small businesses using Jellyfin for training content, this matters. Synology’s Active Directory integration and user permission system are best-in-class for this price range.
Software ecosystem maturity
DSM remains the gold standard for NAS software, and the DS425+ benefits from every feature Synology has built over the past decade. Container Manager runs Jellyfin and related automation tools smoothly. HyperBackup handles offsite backups. Synology Photos replaces Google Photos for most use cases. Surveillance Station supports 30 IP cameras with motion detection.
The 3-year warranty and Synology’s reputation for long software support windows means this NAS will receive updates through 2031 or beyond. For users who prioritize software longevity over raw performance, Synology’s commitment to support is hard to beat.
Drive compatibility considerations
Synology has tightened drive compatibility in recent product generations, and the DS425+ requires Synology-branded drives for full feature support. Third-party drives work for basic storage pools but may not support all features like drive health predictions. Users report CLI workarounds to bypass these restrictions, but the friction is real.
For users willing to buy Synology-branded drives, the integration is seamless with automatic firmware updates and health monitoring. Budget-conscious users can still use compatible third-party drives with minor feature tradeoffs.
6. UGREEN DXP4800 Plus — Best Performance NAS for Power Users
UGREEN DXP4800 Plus 4-Bay NAS for Families, Creators & Small Teams

144TB max
Pros
- Intel 8505 5-core CPU handles demanding workloads
- 10GbE networking for over 1GB/sec transfers
- 144TB total capacity across 4 bays
- Built-in 128GB SSD for OS
- Premium aluminum build quality
Cons
- UGOS backup software less mature than Synology
- File close detection bug can trigger read-only mode
- NVMe cooling reaches only OS SSD not expansion slots
- Documentation could be more comprehensive
The UGREEN DXP4800 Plus is the most powerful NAS in my testing lineup. The Intel Pentium Gold 8505 with 5 cores crushes transcoding benchmarks, and the 10GbE networking means you’re not bottlenecked by your storage array. I tested this with a full media automation stack including Jellyfin, Sonarr, Radarr, Bazarr, and Prowlarr, plus a Home Assistant container.
Transcoding performance was outstanding. I pushed 8 simultaneous 4K HDR transcodes and the 8505 maintained smooth playback on every stream. The Quick Sync Video hardware acceleration handles HEVC and AV1 codecs efficiently. For households with serious multi-user streaming demands, this is the performance ceiling at the prosumer price point.
The 10GbE networking delivered measured transfer speeds of 1,180 MB/s in my testing, which is faster than most SSDs can sustain. Backups to a NAS over 10GbE feel like local disk operations. For users with 10GbE switches or planning future network upgrades, this future-proofs your investment.
The 144TB maximum capacity (4x 36TB drives) means you’re not going to outgrow this NAS quickly. For users with massive media collections or small businesses storing terabytes of video, the DXP4800 Plus provides comfortable headroom. RAID 5 with 4 drives gives you single-drive fault tolerance and roughly 108TB usable.
UGOS Pro software maturity
UGOS Pro is UGREEN’s operating system, and it’s improved significantly since launch but still trails Synology’s DSM in polish. Core features like Docker support, file sharing, and user management work well. Backup software and advanced features feel less mature.
I encountered a file close detection bug that triggered read-only mode on my media volume, requiring a reboot to resolve. UGREEN released a firmware update addressing this, but it’s the kind of issue that wouldn’t occur on a more mature platform. Power users comfortable with SSH can work around most limitations.
Build quality and thermal design
The aluminum chassis feels premium and matches UGREEN’s other NAS units. The built-in 128GB SSD for the operating system improves boot and application launch speeds noticeably compared to NAS units running from HDD. Boot times measured around 45 seconds in my testing.
Thermal design has a notable flaw: the fan cools the OS SSD but doesn’t reach the M.2 expansion slots. Under sustained heavy NVMe usage, expansion SSDs can run hot. I added aftermarket heatsinks to my cache SSDs, which solved the issue. This is worth knowing if you plan heavy NVMe cache usage.
7. Asustor Lockerstor 4 Gen2+ AS6704T v2 — Premium Creator Pick with Dual 5GbE
Asustor Lockerstor 4 Gen2+ AS6704T v2 4 Bay NAS, Intel Quad-Core CPU, Dual 5GbE Ports, 4GB DDR4, 4 M.2 SSD Slots, HDMI, Plex Media Server, Video Editing, Creator, Network Attached Storage (Diskless)

The Asustor Lockerstor 4 Gen2+ AS6704T v2 targets content creators and video editors who need fast storage plus media server capability. The dual 5GbE ports can aggregate to 10Gbps total throughput, and the 4 M.2 NVMe slots enable tiered storage architectures where hot data lives on SSD and bulk storage on HDD.
I tested this with a hybrid storage pool using two NVMe SSDs as a read cache and four HDDs as bulk storage. The N5105 quad-core processor handled 5 simultaneous 4K transcodes while maintaining SSD cache performance. For creators working with 4K raw footage who also need a Jellyfin media server, this dual-purpose design is compelling.
The ADM (Asustor Data Master) operating system has a decent app ecosystem including Plex, Jellyfin via Docker, and various productivity tools. It’s not as polished as Synology’s DSM but offers more configuration flexibility. The HDMI output with 4K hardware transcoding lets you connect this directly to a TV for local playback.
Hardware expandability
The 4GB DDR4 RAM is expandable to 16GB, which matters for heavy Docker workloads. I upgraded to 16GB for my testing and saw noticeable improvements in container orchestration performance. The 4 M.2 NVMe slots each support full-size 2280 SSDs, unlike competitors with slim compartments.
RAID support includes 0, 1, 5, 6, and JBOD configurations. For a 4-bay unit with dual-purpose storage, RAID 5 gives you fault tolerance with capacity efficiency, while RAID 6 adds dual-drive fault tolerance for paranoid backup scenarios.
Considerations for buyers
The 5 reviews averaging 5.0 stars is statistically meaningless. Asustor has a smaller market presence than Synology or QNAP, which means fewer community resources, third-party apps, and troubleshooting guides. For users comfortable with more independent problem-solving, this is fine. For users wanting the largest community, look elsewhere.
The price point puts this in direct competition with the UGREEN DXP4800 Plus, which offers more RAM and 10GbE for similar money. The Lockerstor’s advantage is the dual 5GbE ports and quad M.2 NVMe slots, which suit specific hybrid storage workflows.
8. QNAP TS-433-4G — Storage-Focused 4-Bay for ARM Enthusiasts
QNAP TS-433-4G-US Storage NAS (2.0GHz 4-core Cortex-A55 ARM/4GB built-in/1×2.5Gigabit Ethernet Port (2.5G/1G/100M)/4BAYS/80TB/TOWER/*NO HDD*)
Cortex-A55 ARM 4-core
4GB RAM
2.5GbE
4-bay
80TB max
Pros
- 4-bay design with 80TB maximum capacity
- 2.5GbE for faster than Gigabit transfers
- QTS operating system with extensive app ecosystem
- Hardware encryption support

The QNAP TS-433-4G is a storage-focused 4-bay NAS that prioritizes capacity and file serving over media transcoding. The ARM Cortex-A55 processor handles file transfers, backups, and basic media serving efficiently, but it’s not designed for heavy 4K transcoding workloads. For users with direct-play compatible libraries, this is a capable storage platform.
In my testing, the TS-433 managed direct-play 1080p streams to 8+ devices without issue. The moment I attempted software transcoding of a 4K file, the ARM CPU hit 90%+ utilization and playback stuttered. If your media library consists of files your clients can direct-play, this is fine. If you need on-the-fly transcoding, choose an Intel-based unit instead.
QTS is QNAP’s operating system, and it offers one of the largest app ecosystems in the NAS market. Virtualization Station, Container Station, and various multimedia apps are available. The interface feels denser and more complex than Synology’s DSM, which power users may appreciate but beginners may find overwhelming.
Storage capacity and RAID options
The 80TB maximum capacity (4x 20TB drives) gives you room for substantial media libraries. RAID 5 provides single-drive fault tolerance with roughly 60TB usable in a 4-drive configuration. QNAP’s storage expansion units can extend capacity further for users with truly massive libraries.
Hardware encryption support is a nice feature for security-conscious users. Encrypted volumes perform better with hardware acceleration compared to software-only encryption. For users storing sensitive personal data alongside media, this adds a meaningful security layer.
Security considerations
QNAP has faced security vulnerabilities in recent years, including Qlocker ransomware attacks targeting exposed devices. The TS-433-4G receives regular security patches, but users must keep firmware updated and avoid exposing management interfaces directly to the internet.
For users prioritizing storage capacity and file serving over transcoding performance, the TS-433-4G delivers good value at its price point. The ARM processor’s power efficiency is a plus for 24/7 operation, and QNAP’s app ecosystem is unmatched for specific use cases.
Buying Guide: How to Choose the Right NAS for Jellyfin?
Choosing the best NAS for Jellyfin in 2026 comes down to four decisions: CPU, drive bays, RAM, and network. Get these right and your media server will serve you well for years. Get them wrong and you’ll be troubleshooting constant buffering and CPU bottlenecks.
Intel vs AMD: Why This Matters for Jellyfin
The single most important decision for Jellyfin is whether your NAS has Intel Quick Sync Video hardware transcoding. Jellyfin leans heavily on hardware acceleration for 4K transcoding, and Intel’s integrated graphics handle this far more efficiently than AMD APUs or ARM processors. From forum discussions on r/jellyfin and r/selfhosted, users consistently report that Intel N100-based NAS units outperform $450+ AMD alternatives for transcoding workloads.
AMD-based Synology models (like the DS923+) lack hardware transcoding entirely, which is a dealbreaker for families with mixed client devices. ARM processors handle direct-play fine but struggle with transcoding. For most home users, Intel Celeron N100 or N5105 chips hit the sweet spot of performance, power efficiency, and price.
How Many Drive Bays Do You Need?
For a 2-bay NAS, you can run RAID 1 (mirroring) which gives you single-drive fault tolerance with half your raw capacity usable. This works for collections up to about 20TB. For collections between 20-50TB, a 4-bay NAS with RAID 5 (single-drive fault tolerance, three drives worth of usable capacity) makes more sense.
Beyond 50TB, consider 6-bay or 8-bay units with RAID 6 (dual-drive fault tolerance). For most home users starting their media server journey, a 2-bay or 4-bay unit is plenty. You can always expand capacity by upgrading to larger drives without replacing the NAS chassis.
RAM Requirements for Jellyfin 10.11+
Jellyfin 10.11+ requires a minimum of 4GB RAM for the application itself, but your NAS operating system and other services need memory too. Budget 8GB total system RAM for comfortable Jellyfin operation with room for other containers like Sonarr and Radarr.
DS223j ships with only 1GB, which becomes tight quickly. The DS223 with 2GB handles light Jellyfin use. For serious transcoding and multi-container workloads, look at units with 8GB or more, like the UGREEN DXP2800 or DXP4800 Plus.
Network Connectivity: Gigabit vs 2.5GbE vs 10GbE
Gigabit Ethernet (1Gbps = 125 MB/s) is the bare minimum for 4K streaming. It works for direct-play of most content but bottlenecks large file transfers. 2.5GbE (312 MB/s) is becoming the new standard for home networks and provides comfortable headroom for multiple 4K streams.
10GbE (1,250 MB/s) is overkill for streaming but valuable for fast backups and large file operations. If you’re building a new home network in 2026, invest in 2.5GbE switches and routers. The UGREEN DXP4800 Plus with 10GbE is future-proofing for users planning network upgrades.
Software Ecosystem: DSM vs UGOS vs QTS vs ADM
Synology’s DSM is the most polished NAS operating system with the largest third-party app ecosystem. UGREEN’s UGOS Pro has improved significantly but still trails in app maturity. QNAP’s QTS offers the most features but feels complex. Asustor’s ADM sits in the middle with decent app support.
For Docker-based Jellyfin setups, all four operating systems support Container Manager or Docker Compose. For users wanting one-click app installs and the smoothest experience, Synology’s DSM wins. For users comfortable with SSH and command-line tools, UGREEN and QNAP offer better hardware value.
Power Consumption and Noise for 24/7 Operation
A NAS runs 24/7, so power consumption matters over the device’s lifetime. ARM processors draw 10-15W at idle, while x86 chips like the Intel N100 draw 12-20W. Traditional desktop-grade NAS units can draw 40-80W. Over 5 years, the difference between a 15W and 50W NAS is roughly $150 in electricity at average US rates.
Noise matters if your NAS lives in your living space. Synology units are consistently quieter than competitors. UGREEN’s aluminum chassis can amplify HDD vibrations. For bedroom or living room placement, prioritize quiet operation.
