Running virtual machines on a NAS changed my entire approach to homelab computing. Instead of maintaining separate servers for Plex, Home Assistant, and development environments, I consolidated everything into a single, efficient box. After testing 6 NAS units over several months, I found the best NAS for hosting virtual machines in 2026.
A NAS designed for VM workloads needs more than storage capacity. It requires a capable CPU, sufficient RAM, and network throughput that will not bottleneck your virtual machines. I tested each of these units with real workloads, from Docker containers to full Windows VMs.
The biggest lesson from my testing: entry-level NAS models fall short for virtualization. Limited RAM, weak processors, and 1GbE networks create bottlenecks that make VMs feel sluggish. Every unit in this guide avoids at least two of those three traps.
This guide covers the best NAS for hosting virtual machines, with specific recommendations for homelab enthusiasts, small businesses, and everyone in between. I will walk you through what makes each model shine and where it falls short.

I set up the Synology DS925+ in my home office expecting a typical NAS experience. What I found was something far more polished. The DSM operating system makes virtual machine management feel approachable even for beginners. Within an hour, I had a Ubuntu VM running alongside my file storage.
The AMD Ryzen V1500B quad-core processor handles light VM workloads without breaking a sweat. I ran a Home Assistant VM and two Docker containers simultaneously. Performance remained snappy throughout my testing. The 4GB of included RAM is enough to start, but you will want to upgrade for serious VM work.
Dual 2.5GbE ports gave me network speeds around 280 MB/s during large file transfers. For VM workloads, this throughput means your virtual machines respond quickly even when accessed remotely. I tested VM migration between the DS925+ and another NAS, and the process was surprisingly smooth.
Synology’s Virtual Machine Manager offers a clean interface for creating and managing VMs. I appreciated the snapshot feature, which saved me when I broke a Linux installation during testing. One click restored my VM to a working state.
Synology briefly restricted 2025-era models to Synology-branded drives, then reversed that decision. My unit accepted third-party Samsung drives without complaints after that reversal. That matters when you are budgeting drives for a VM lab.
Who Should Buy This NAS
The Synology DS925+ is ideal for homelab beginners who want a stable, user-friendly platform for running a few VMs alongside file storage. If you value software polish over raw specs, this is your NAS. It also suits small offices needing reliable backup with occasional VM use.
Who Should Look Elsewhere
Power users running multiple heavy VMs will find the 4GB RAM limiting. The premium pricing on Synology-branded upgrades adds to the total cost. If you need 10GbE networking out of the box, look at the UGREEN DXP4800 Plus instead.
2. Synology DS1621+ – Best Value NAS for VM Hosting
Synology 6 bay NAS DiskStation DS1621+ (Diskless)
AMD Ryzen V1500B
4GB ECC RAM
6 Bays
Expandable to 16 Drives
Pros

The Synology DS1621+ became my daily driver for serious VM work. The six drive bays give you flexibility that smaller NAS units simply cannot match. I filled mine with a mix of high-capacity HDDs for storage and NVMe SSDs for VM boot drives. The result was a responsive system that handled everything I threw at it.
ECC memory support sets this NAS apart from consumer-focused competitors. For VM hosting, ECC RAM means data integrity when your virtual machines are running 24/7. I ran multiple VMs for weeks without a single memory-related error. That reliability matters when your VMs run critical services.
The expansion capability is what sold me. With DX517 units, you can scale to 16 drives without migrating data. My test unit started with 6 drives and grew to 11 as my storage needs increased. The SHR RAID system handled mixed drive sizes without any manual configuration.
Synology claims 174% higher 4K random read IOPS than the previous generation. In practice, that translated to faster VM boot times and smoother database workloads inside my virtual machines. The dual M.2 NVMe slots make a real difference once you enable SSD caching.
My only real complaint is the stock 1GbE networking. For a NAS this capable, 10GbE should come standard. I added a 10GbE NIC which required opening the case. The performance improvement was dramatic, but budget for that upgrade if you move large VM disks regularly.
Who Should Buy This NAS
The Synology DS1621+ fits homelab enthusiasts and small businesses needing expandable storage with reliable VM support. If you anticipate growing your storage over time, the expansion bays make this the most future-proof option. It also suits users who prioritize software stability over cutting-edge specs.
Who Should Look Elsewhere
If you need fast networking out of the box, the 1GbE limitation will frustrate you. Users running just 2-4 drives may find the six-bay capacity unnecessary. The premium price makes less sense if you never plan to expand beyond the base configuration.
3. QNAP TS-464-8G-US – Best QNAP for VM Workloads

Testing the QNAP TS-464-8G-US revealed a NAS with solid hardware hampered by noise issues. The Intel Celeron N5095 quad-core processor handled my VM workloads competently. I ran a Windows VM and several Docker containers without performance complaints. The 8GB of RAM provided more headroom than the 4GB Synology units.
Dual M.2 NVMe slots let me add SSD caching for improved VM performance. I installed a pair of budget NVMe drives and saw noticeable improvements in VM boot times. The hot-swappable drive bays made maintenance easy without shutting down the system.
The fan noise became my biggest frustration. In my home office, the constant drone made concentration difficult. I tried adjusting fan settings in QTS, but the noise persisted. Forum posts confirmed this is a known issue with the TS-464 series. Many users replace the stock fans with quieter aftermarket options.
Windows network discovery also caused headaches. My Windows 11 machine could not find the NAS in File Explorer. I had to use QNAP’s Qfinder Pro utility instead. This is a known issue with WS-Discovery and SMB on Windows 10/11. Workarounds exist, but they add complexity to what should be simple.
Who Should Buy This NAS
The QNAP TS-464 suits users with dedicated server rooms or closets where fan noise will not matter. If you need 8GB of RAM included and do not want to pay for upgrades, the stock memory is generous. IT professionals comfortable with network troubleshooting will find the hardware capable.
Who Should Look Elsewhere
Anyone planning to place this NAS in a living space or quiet office should reconsider. The fan noise is genuinely intrusive for extended work sessions. Windows users expecting plug-and-play network discovery may find the workarounds frustrating.
4. QNAP TS-264-8G-US – Best Compact NAS for VMs
QNAP TS-264-8G-US 2 Bay Desktop NAS
Intel Celeron N5095
8GB DDR4 RAM
2 Bays
Dual 2.5GbE
Pros

The QNAP TS-264-8G-US surprised me with how much capability fits in a compact 2-bay design. After using ARM-based QNAP models, the Intel Celeron N5095 felt like a revelation. VMs launched quickly, and Docker containers ran smoothly. For a budget-friendly NAS, the performance impressed me.
I tested this unit specifically as a media server running Jellyfin. The quad-core processor handled transcoding without stuttering. Combined with the 8GB of RAM, I could run a media server, Home Assistant, and several lightweight VMs simultaneously. For homelab use, this little NAS delivers surprising value.
Dual M.2 slots gave me caching options that improved overall responsiveness. I used one slot for read caching and noticed faster access to frequently used files. The 2.5GbE network ports provided plenty of bandwidth for my VM traffic and media streaming.
The obvious limitation is storage capacity. Two bays mean you are restricted to RAID 0, RAID 1, or JBOD. I would not recommend this for critical data without proper backups. But for VM hosting where speed matters more than capacity, the compact design makes sense.
Who Should Buy This NAS
The QNAP TS-264 suits homelab users with limited space who still want VM capability. If your primary use case is running Docker containers and lightweight VMs, this NAS offers excellent value. Media server enthusiasts will appreciate the transcoding performance in a compact package.
Who Should Look Elsewhere
Users needing serious storage capacity should look at 4-bay or larger options. The 2-bay design limits your RAID options and total storage. If you plan to run multiple heavy VMs, the 8GB RAM ceiling may constrain you over time.

Buying Guide: How to Choose a NAS for Hosting Virtual Machines?
Choosing the best NAS for hosting virtual machines requires understanding how specific hardware affects VM performance. I learned through testing that storage capacity alone tells you nothing about VM capability. Here is what actually matters.
CPU and RAM Requirements
The processor determines how many VMs your NAS can run simultaneously. Intel Celeron and Pentium processors handle 2-4 lightweight VMs comfortably. AMD Ryzen chips in Synology units offer similar performance. For heavy workloads, look at the Intel Core i3 in the TerraMaster F4-424 Pro.
RAM matters as much as the CPU. Each VM needs dedicated memory that cannot be shared. I recommend a minimum of 8GB for running 2-3 VMs. For serious VM workloads, 16GB to 32GB provides headroom for growth. The TerraMaster’s 32GB and UGREEN’s expandable DDR5 slots both serve this need well.
Storage Configuration
More bays mean more flexibility. A 2-bay NAS limits you to RAID 0 or RAID 1. A 4-bay NAS enables RAID 5 or RAID 10, providing better redundancy and performance. The Synology DS1621+ with its 6 bays and expansion capability offers the most storage options.
M.2 NVMe slots dramatically improve VM performance. I used these for SSD caching and as dedicated VM boot drives. The performance difference was immediately noticeable. All six NAS units in this guide include M.2 slots, which I consider essential for VM workloads.
Network Connectivity
Network speed directly affects VM responsiveness, especially when accessing VMs remotely. 1GbE creates bottlenecks for disk-intensive VMs. 2.5GbE provides a meaningful improvement for home networks. 10GbE, found on the UGREEN DXP4800 Plus, eliminates network bottlenecks entirely for most users.
Consider your network infrastructure before choosing. A 10GbE NAS requires a 10GbE switch or direct connection to benefit from the speed. If your network is limited to 1GbE, investing in 10GbE hardware now still prepares you for future upgrades.
Virtualization Software
Synology’s Virtual Machine Manager offers the most polished experience for beginners. QNAP’s Virtualization Station provides more features but with a steeper learning curve. TerraMaster and UGREEN support Docker and VMs through their respective interfaces, with varying levels of refinement.
Consider what you plan to run. Docker containers are lighter weight and easier to manage than full VMs. If containers meet your needs, any of these NAS units handles them well. Full VMs require more resources and benefit from the hardware recommendations above.
Containers vs Virtual Machines on a NAS
Containers share the host kernel, which makes them dramatically lighter than full VMs. A Docker container running the same service might use 200MB of RAM while a full VM needs 2GB. If you are running self-hosted apps like Plex, Pi-hole, or the arr stack, containers are the better fit.
Virtual machines make sense when you need a different operating system or full isolation. Windows gaming servers, specialized Linux distros, and testing environments all benefit from VMs. VMs also give you snapshot and rollback capabilities that containers handle differently.
My approach after months of testing: run containers for services and one VM for anything requiring a full OS. This hybrid strategy keeps resource usage low while maintaining flexibility. Every NAS in this guide handles both workloads.
ECC Memory Considerations
ECC memory detects and corrects data corruption. For VMs running 24/7, this protection prevents silent data corruption that could corrupt virtual disks. The Synology DS1621+ includes ECC support, which matters for critical workloads.
Consumer NAS units often lack ECC memory to reduce costs. For homelab use, non-ECC RAM is generally acceptable. For business use or critical data, prioritize ECC-capable units like the DS1621+. Your tolerance for risk should guide this decision.
Power Consumption and Noise
Nobody in the competitor coverage talks about power draw, but it matters for a device running 24/7. A NAS idling at 30W costs roughly $32 per year to run at average US rates. Add VM workloads and that figure climbs, since the CPU stays busier and fans spin harder.
Quiet operation matters just as much for home offices. The Synology DS925+ on cool mode and the UGREEN DXP4800 Plus both stayed unobtrusive on my desk. The QNAP TS-464 was the loudest unit I tested. If the NAS lives in your workspace, factor noise into your decision before buying.
