Best NAS for Virtualisation Australia 2026

Running virtual machines on a NAS demands significantly more hardware than file storage, media streaming, or even Docker containers. You need an x86 processor with hardware virtualisation extensions (VT-x/AMD-V), a minimum of 8GB RAM (16GB+ recommended), and fast storage to avoid crippling I/O bottlenecks. Most entry-level and mid-range NAS devices sold in Australia lack the CPU or memory to run even a single lightweight VM comfortably. This guide identifies the NAS models that can genuinely handle virtualisation workloads, with real Australian pricing from major retailers.

For a broader overview of this topic, see our NAS buying guide hub.

Virtualisation on a NAS: What It Actually Means

Virtualisation on a NAS means running full virtual machines. Complete operating systems like Windows Server, Ubuntu, or pfSense. Inside a hypervisor that runs on top of the NAS operating system. This is fundamentally different from Docker containers, which share the host kernel and use far fewer resources. A single Windows VM can consume 2-4GB of RAM and two or more CPU cores before you have done anything useful with it.

The major NAS platforms each handle virtualisation differently. QNAP offers Virtualisation Station, a full KVM-based hypervisor built into QTS. Synology provides Virtual Machine Manager (VMM) on its Plus and above models. Asustor supports VirtualBox through its ADM platform. The level of integration, performance, and usability varies significantly between these implementations. And it matters more than raw specs when deciding which NAS to buy for virtualisation.

For a broader comparison of Docker versus full virtualisation on NAS platforms, see our Docker and virtualisation on NAS deep dive. If you are primarily interested in running containers rather than full VMs, our best NAS for Docker and home automation guide is a better starting point.

Why Run VMs on a NAS Instead of a Separate Server?

For Australian home labs and small businesses, a virtualisation-capable NAS consolidates two devices into one. Instead of running a separate server alongside a NAS, you get file storage, backup, and virtualisation in a single appliance. That means one power bill (NAS devices draw 30-80W versus 100-300W for a tower server), one device to manage, and one footprint in your office or rack.

Common virtualisation use cases on a NAS include running a pfSense or OPNsense firewall VM, hosting a Windows development environment, running a Linux test lab, operating a Pihole or DNS server, or spinning up isolated environments for software testing. Small businesses sometimes run lightweight Windows Server VMs for Active Directory, file sharing, or internal applications. Though for anything production-critical, a dedicated server remains the safer choice.

What to Look for in a Virtualisation NAS

CPU: Hardware Virtualisation Is Non-Negotiable

The CPU must support hardware virtualisation extensions. Intel VT-x or AMD-V. Without these, the NAS hypervisor cannot run VMs at near-native speed, and performance drops dramatically. Every ARM-based NAS (Synology DS223, QNAP TS-233, Asustor Drivestor series) is immediately ruled out. Many Intel Celeron models technically support VT-x but lack the multi-threaded performance to run VMs alongside NAS duties without constant bottlenecking.

For virtualisation, look for AMD Ryzen embedded processors (V1500B, V3C14, R1600) or Intel Core i3/i5 chips. These provide genuine multi-core, multi-threaded performance that can be allocated across VMs without starving the NAS operating system. The Celeron N5095/N5105 found in many mid-range NAS units can technically run a single lightweight VM, but stacking VMs on a Celeron is an exercise in frustration.

RAM: 8GB Is the Bare Minimum, 16GB+ Is Practical

RAM is the single biggest constraint for NAS virtualisation. The NAS OS itself needs 1-2GB. A basic Linux VM needs 1-2GB. A Windows VM needs 4GB minimum to be usable. Run the NAS OS plus one Windows VM and one Linux VM, and you are at 8-10GB before adding any other services. If you plan to run multiple VMs or combine virtualisation with Docker containers, 16GB is the practical starting point and 32GB gives breathing room.

Critically, check whether the NAS supports ECC (Error-Correcting Code) RAM. For virtualisation workloads where data integrity matters. Especially if running database or file server VMs. ECC RAM prevents single-bit memory errors from corrupting your VM data. The Synology DS1525+ and QNAP TS-473A both support ECC RAM. Non-ECC models work fine for home labs, but ECC is worth pursuing for any business-adjacent virtualisation.

Storage: NVMe Makes or Breaks VM Performance

Running VMs on spinning hard drives is painful. Every VM boot, application load, and file operation competes with your regular NAS storage I/O. The result is sluggish VMs and degraded NAS performance for everyone else on the network. If you are serious about virtualisation, you need NVMe SSD storage. Either via M.2 slots on the NAS or by using 2.5-inch SATA SSDs in your drive bays.

Most current NAS models include M.2 NVMe slots intended for caching, but on some platforms (Synology DSM 7.2+, QNAP QTS) these can be configured as dedicated storage pools. Placing your VM images on NVMe storage while keeping bulk data on HDDs is the ideal configuration. For more on SSD storage options, see our SSD cache and all-flash NAS guide.

Networking: 2.5GbE Minimum, 10GbE for Serious Use

VMs running on a NAS share the NAS network connection for all their traffic. If you are running a firewall VM or a file server VM, network bandwidth becomes a real concern. Standard 1GbE is a bottleneck as soon as you have multiple VMs and NAS duties competing for bandwidth. Dual 2.5GbE ports with link aggregation provide adequate headroom for most home lab scenarios. For small business deployments or heavy virtualisation use, a 10GbE-capable NAS (or one with a PCIe slot for a 10GbE card) is worth the investment. See our NAS networking guide for setup details.

Best NAS for Virtualisation. Top Picks

Best Overall: QNAP TS-473A-8G

The QNAP TS-473A is purpose-built for virtualisation workloads. The AMD Ryzen V1500B quad-core processor (8 threads, 2.2GHz) provides genuine multi-threaded performance with full AMD-V virtualisation support. It ships with 8GB of RAM expandable to 64GB. Giving you the headroom to run multiple VMs concurrently as your needs grow. Four 3.5-inch SATA bays plus two M.2 NVMe slots allow you to separate VM storage (NVMe) from bulk data (HDD).

QNAP's Virtualisation Station is the most capable NAS hypervisor available. It supports Windows, Linux, and Unix VMs with VGA output, USB device passthrough, and VM snapshot management. A PCIe Gen 3 expansion slot lets you add a 10GbE card for network-intensive VM workloads or additional NVMe storage. Dual 2.5GbE ports handle typical home lab traffic comfortably.

At $1,369 from Scorptec ($1,489 at PLE), the TS-473A sits at a higher price point than Celeron-based alternatives, but the Ryzen processor and 64GB RAM ceiling justify the premium for anyone planning to run more than one VM. For a full brand comparison, see our Synology vs QNAP guide or the detailed QNAP TS-464 review for context on the QNAP lineup.

Best Synology Option: Synology DS1525+

The Synology DS1525+ pairs the same AMD Ryzen V1500B processor as the QNAP TS-473A with 8GB of ECC DDR4 RAM expandable to 32GB. Five drive bays (plus two M.2 NVMe slots) give you more storage flexibility than any 4-bay model, and ECC RAM provides data integrity assurance that matters for virtualisation workloads. Synology's Virtual Machine Manager (VMM) supports Windows, Linux, and DSM virtual instances with live migration between compatible Synology NAS units.

VMM is less feature-rich than QNAP's Virtualisation Station. It lacks HDMI output for VMs and has fewer hardware passthrough options. But it integrates seamlessly with DSM's storage, snapshot, and backup ecosystem. For Synology users, the ability to snapshot and replicate VMs using Hyper Backup and Snapshot Replication adds a data protection layer that QNAP's offering does not match as cleanly.

At $1,285 from Mwave ($1,399 from Scorptec), the DS1525+ is competitive with the TS-473A. The trade-off is a lower RAM ceiling (32GB versus 64GB) but ECC support and five bays. For a closer look at the Synology ecosystem, see our Synology DS925+ review or the Synology NAS Australia hub.

Best Value for Raw Performance: TerraMaster F4-424 Pro

On paper, nothing in this price range touches the TerraMaster F4-424 Pro for virtualisation hardware. An Intel Core i3-N305 (8 cores, 8 threads) with 32GB of DDR5 RAM at $1,099 from Scorptec ($1,100 at Mwave) is a staggering amount of compute for under $1,100. The i3-N305 supports VT-x with EPT (Extended Page Tables), making it fully capable of running multiple VMs efficiently. Dual 2.5GbE networking rounds out a specification sheet that embarrasses the competition at this price.

The catch is TerraMaster's software. TOS (TerraMaster Operating System) supports virtualisation through third-party tools, but the experience is less polished than QNAP's Virtualisation Station or Synology's VMM. Users comfortable installing and managing VMs via command-line tools or Proxmox (which some enthusiasts install on TerraMaster hardware, voiding the warranty) will extract enormous value from this unit. Users who want a GUI-driven virtualisation experience with vendor support should look at QNAP or Synology instead.

TerraMaster's Australian distribution runs through DSTech, which has limited presence. Stock can be inconsistent, and warranty support is less established than Synology through BlueChip or QNAP through BlueChip/Dicker Data. Don't buy this if you need reliable after-sales support in Australia. It suits technically confident users who prioritise hardware specs per dollar and can self-manage virtualisation tooling. See our TerraMaster NAS Australia guide for more context.

Best for Budget Virtualisation: QNAP TS-464-8G

If your virtualisation needs are modest. A single Linux VM for testing, a lightweight Windows instance, or a pfSense firewall VM alongside regular NAS duties. The QNAP TS-464 at $999 from Scorptec offers a lower entry point than the TS-473A. The Intel Celeron N5095 supports VT-x and can handle one or two lightweight VMs. It ships with 8GB of RAM (expandable to 16GB), dual 2.5GbE, two M.2 NVMe slots, and a PCIe Gen 3 expansion slot.

The TS-464 still runs QNAP's Virtualisation Station, giving you the same VM management interface as the TS-473A. The limitation is the Celeron processor. Four cores with four threads means you have fewer resources to allocate, and CPU-intensive VM tasks will bog down. The 16GB RAM ceiling also limits how many VMs you can run concurrently. This is a NAS that can do virtualisation as a secondary function, not a NAS built for virtualisation as a primary workload.

The TS-464 suits home lab enthusiasts who want to experiment with VMs without committing to a Ryzen-based NAS. If you find yourself outgrowing it, the PCIe slot at least allows a 10GbE upgrade. For a detailed assessment, see our QNAP TS-464 review.

Step-Up Pick: Asustor Lockerstor 4 Gen3 AS6804T

The Asustor Lockerstor 4 Gen3 AS6804T brings the AMD Ryzen V3C14 processor and 16GB of RAM to the table at $1,799 from Scorptec ($2,175 at Mwave). The V3C14 is a newer-generation embedded Ryzen with four cores and strong single-threaded performance, paired with dual 5GbE networking. A step above the 2.5GbE found on competing models. Four 3.5-inch bays plus M.2 NVMe slots provide flexible storage configuration.

Asustor's ADM platform supports VirtualBox for virtualisation, which is a familiar tool for anyone who has used VMs on a desktop. It is functional but less deeply integrated than QNAP's Virtualisation Station or Synology's VMM. The 16GB of RAM ships ready for immediate multi-VM use without needing an upgrade, which is a genuine advantage over models that ship with 8GB and require an immediate purchase.

At $1,799, the AS6804T is a significant price premium over the QNAP TS-473A. The justification is the newer CPU, 16GB stock RAM, and dual 5GbE networking. It suits users who value out-of-the-box readiness and faster networking but are comfortable with Asustor's smaller ecosystem. Asustor's Australian distribution is through Dicker Data, which holds modest stock. Availability can be inconsistent for newer models. See our Asustor NAS Australia guide for more on the brand.

NAS Models to Avoid for Virtualisation

Many NAS devices are marketed as capable of "everything" but are wholly unsuitable for virtualisation. Avoid these categories:

ARM-based NAS units: The Synology DS223 ($489 at Scorptec), DS124 (~$445 at Scorptec), QNAP TS-233 ($399 at Scorptec), and all Asustor Drivestor models use ARM processors that cannot run x86 virtual machines. These are file storage devices, not virtualisation platforms.

2GB and 4GB RAM models: The Synology DS225+ ($549 at Scorptec) ships with 2GB of RAM. The Synology DS925+ ($995 at Scorptec) ships with 4GB. While both support RAM upgrades and have x86 CPUs, running VMs on 2-4GB of total system RAM is not viable. If you choose either of these models for virtualisation, budget for an immediate RAM upgrade to at least 8GB.

Models without virtualisation software: Not every x86 NAS includes a hypervisor. The Asustor Nimbustor AS5404T ($799 at Scorptec) has a Celeron N5105 and can technically run VMs through VirtualBox, but the combination of 4GB RAM and a budget processor makes it better suited to Docker workloads than virtualisation. Similarly, the Synology DS425+ ($819 at Scorptec) has the CPU but ships with insufficient RAM for VM use.

Virtualisation Platform Comparison: QNAP vs Synology vs Asustor

QNAP Virtualisation Station

QNAP's Virtualisation Station is the most full-featured NAS hypervisor. Built on KVM (Kernel-based Virtual Machine), it supports Windows, Linux, Unix, and Android VMs. Key features include VM snapshots, USB device passthrough to VMs, HDMI output for direct VM console access, and support for importing VMware and VirtualBox VM images. QTS also allows running Virtualisation Station alongside Container Station, so you can mix VMs and Docker containers on the same NAS.

The main downside is that QNAP's QTS platform has historically been a bigger target for security vulnerabilities than Synology's DSM. If you run a QNAP NAS with virtualisation enabled, keep firmware updated and avoid exposing the management interface to the internet. Use a VPN for remote access instead. Our NAS security and ransomware protection guide covers the essentials.

Synology Virtual Machine Manager (VMM)

Synology's VMM is more conservative than QNAP's approach. It supports Windows, Linux, and DSM virtual instances, with VM snapshots and the ability to replicate VMs to a secondary Synology NAS for disaster recovery. VMM integrates with Synology's storage manager, making it straightforward to allocate storage pools and volumes for VM use.

VMM lacks HDMI output for direct VM console access and has fewer hardware passthrough options than Virtualisation Station. It also restricts virtualisation to Plus-series and above models. Value-series Synology NAS units cannot run VMM at all. The strength of VMM is its integration with DSM's broader ecosystem: Active Backup for Business can back up VMs, Hyper Backup can replicate them offsite, and the overall experience is cleaner and more reliable than QNAP's, if less flexible.

Asustor VirtualBox

Asustor offers VirtualBox through ADM's App Central. This is Oracle's VirtualBox running on the NAS. The same application you might use on a desktop PC. It works, but the integration is superficial compared to QNAP or Synology's purpose-built hypervisors. VM management is handled through VirtualBox's web interface rather than a NAS-native dashboard, and storage allocation requires more manual configuration.

VirtualBox on Asustor suits users who already know VirtualBox from desktop use and want a familiar interface. It is less suitable for users who expect a tightly integrated NAS virtualisation experience. For most buyers, QNAP or Synology offers a more cohesive virtualisation workflow.

Setting Up VMs on Your NAS: Practical Advice

Regardless of which NAS you choose, follow these practices for a workable virtualisation setup:

Separate VM storage from data storage. Place VM images on NVMe SSDs (via M.2 slots or a dedicated SSD pool) and keep your file shares, media, and backups on spinning drives. This prevents VM I/O from degrading NAS performance for other users and services.

Allocate resources conservatively. Do not assign all available RAM and CPU cores to VMs. Reserve at least 2GB of RAM and one CPU core for the NAS operating system. Over-allocating resources to VMs will make the NAS interface unresponsive and can cause stability issues.

Use VM snapshots before making changes. Both QNAP Virtualisation Station and Synology VMM support VM snapshots. Take a snapshot before installing updates, changing configurations, or testing software. If something breaks, you can roll back in seconds rather than rebuilding from scratch.

NBN and Remote Access for NAS VMs

If you need to access VMs running on your NAS remotely. Via RDP for a Windows VM, or SSH for Linux. Your NBN upload speed determines the experience. On a standard NBN 100 plan, upload speeds sit around 20-40 Mbps. This is adequate for SSH and basic RDP sessions but will feel sluggish for graphically intensive remote desktop use.

CGNAT (Carrier-Grade NAT) is a bigger concern. If your ISP uses CGNAT. Common on Starlink, some 5G fixed wireless, and budget RSPs. You cannot connect directly to your NAS VMs from outside your home network. Tailscale (a WireGuard-based mesh VPN that works behind CGNAT) is the simplest solution, creating a private network between your devices regardless of NAT configuration. Alternatively, Cloudflare Tunnels or a VPN running on the NAS itself can provide access. See our NAS remote access and VPN guide for detailed setup instructions.

Warranty, Support, and Where to Buy

A NAS running virtualisation workloads is more likely to be stressed than one handling basic file storage. Higher sustained CPU load, more RAM utilisation, and heavier storage I/O mean the hardware works harder for longer. This makes where you buy. And the warranty support behind it. More important than usual.

NAS vendors do not have service centres in Australia. Warranty claims follow the chain: retailer to distributor (BlueChip for Synology and QNAP, Dicker Data for Asustor and QNAP) to the vendor in Taiwan, then back again. Expect 2-3 weeks minimum for a resolution. For a NAS running production VMs, that downtime can be significant.

Buying from specialist retailers like Scorptec or PLE gives you access to genuine pre-sales advice and an established warranty process. Amazon AU often undercuts these retailers, but if your NAS fails while running VMs, Amazon will push a credit or refund rather than working through the distributor chain to source a direct replacement. For virtualisation use where continuity matters, the support safety net of a specialist retailer justifies any price premium. See our where to buy NAS Australia guide for more detail.

Backup Your VMs. A NAS Is Not a Backup

A NAS running VMs is still a single point of failure. If the NAS hardware fails, every VM on it goes down simultaneously. VM configurations, disk images, and the data inside them need their own backup strategy, separate from your regular NAS backup.

On Synology, VMM snapshots combined with Hyper Backup can replicate VM images to a cloud service or secondary NAS. On QNAP, Hybrid Backup Sync can do the same for Virtualisation Station VMs. At minimum, export VM configurations and critical VM data to an offsite location regularly. A 3-2-1 backup strategy. Three copies of data, on two different media, with one offsite. Applies to VMs just as much as it applies to family photos and business documents.

Final Verdict

For serious NAS virtualisation in Australia, the choice comes down to the QNAP TS-473A and the Synology DS1525+. The TS-473A wins on virtualisation features. Virtualisation Station is more capable than VMM, the 64GB RAM ceiling is higher, and a PCIe slot allows 10GbE expansion. The DS1525+ wins on ecosystem polish, ECC RAM support, and Synology's superior security track record.

If budget drives the decision, the TerraMaster F4-424 Pro at $1,099 delivers 32GB of RAM and an 8-core processor that no other NAS at this price can match. But the software experience is a clear step below QNAP and Synology. The QNAP TS-464 at $999 provides a legitimate entry point for light virtualisation alongside Docker and NAS duties.

Whatever you choose, plan for the limits of NAS virtualisation. These are embedded processors with limited RAM ceilings running on shared storage. They handle home labs and lightweight business VMs capably, but they are not replacements for dedicated virtualisation servers. Buy from a retailer that will support you through the warranty process, keep your firmware updated, and back up your VMs independently of your NAS. For broader NAS buying guidance, see our best NAS Australia roundup.

Can I run Windows virtual machines on a NAS?

Yes, but only on NAS models with x86 processors that support hardware virtualisation (VT-x or AMD-V) and sufficient RAM. The QNAP TS-473A and TS-464 both run Windows VMs through Virtualisation Station. The Synology DS1525+ supports Windows VMs through VMM. A Windows VM needs at least 4GB of RAM allocated to it, so plan for a minimum of 8GB total system RAM (with 16GB strongly recommended). ARM-based NAS units cannot run Windows VMs under any circumstances.

How many virtual machines can a NAS run simultaneously?

It depends on the NAS hardware and the resource demands of each VM. A QNAP TS-473A with 32GB of RAM (after upgrading from 8GB) can comfortably run 3-5 lightweight Linux VMs or 2-3 Windows VMs alongside regular NAS duties. A Celeron-based NAS like the TS-464 with 16GB RAM is limited to 1-2 lightweight VMs before performance degrades noticeably. The practical limit is always RAM first, then CPU cores. Monitor resource usage and do not over-commit.

Is QNAP or Synology better for virtualisation?

QNAP has the edge for virtualisation specifically. Virtualisation Station is more feature-rich than Synology's VMM, with HDMI output for direct VM console access, broader OS support, and more hardware passthrough options. QNAP also offers higher maximum RAM (64GB on the TS-473A versus 32GB on the DS1525+). Synology's advantage is tighter integration with DSM's backup and replication tools, ECC RAM support on the DS1525+, and a stronger overall security posture. If virtualisation is your primary use case, QNAP is the stronger choice. If virtualisation is one function among many and you value ecosystem polish, Synology is the safer bet.

Do I need ECC RAM for virtualisation on a NAS?

ECC RAM is not strictly required for home lab virtualisation. Non-ECC RAM works fine for testing, development, and personal projects. However, if you are running VMs that handle important data. A file server VM, a database, or any business-adjacent workload. ECC RAM provides protection against single-bit memory errors that could corrupt data silently. The Synology DS1525+ supports ECC RAM. For most home users, the cost and availability constraints of ECC modules make non-ECC the practical choice, but it is worth considering for serious deployments.

Can I install Proxmox or ESXi on a NAS instead of using the built-in hypervisor?

Technically yes, but it voids the warranty and eliminates the NAS operating system entirely. Some enthusiasts install Proxmox VE on TerraMaster or QNAP hardware to get a full-featured, enterprise-grade hypervisor. This gives you far more control and capability than any NAS hypervisor, but you lose the NAS interface, app ecosystem, and vendor support. If you want Proxmox, consider buying a purpose-built mini PC or server instead. You get the same result without sacrificing a NAS warranty and without fighting hardware compatibility issues.

Should I use Docker containers instead of VMs on my NAS?

In most cases, yes. Docker containers are lighter, faster, and consume far fewer resources than full VMs. If your workload can run in a container. Web servers, media management, home automation, development tools. Docker is the better choice on a NAS. VMs are only necessary when you need a full operating system (Windows applications, network appliances like pfSense, or isolated testing environments that require their own kernel). Our Docker vs virtualisation guide covers the decision in detail. Many NAS users run Docker for most services and keep VMs for the few tasks that genuinely require them.

What happens to my VMs if my NAS fails under warranty in Australia?

If your NAS fails, all VMs stored on it become inaccessible until the hardware is repaired or replaced. The standard warranty process in Australia runs through the retailer to the distributor (BlueChip, Dicker Data) to the vendor in Taiwan. Expect 2-3 weeks minimum. Advanced replacements are not officially supported by most NAS vendors. This is why backing up VM images and configurations to a separate location is critical. Your warranty covers the hardware, not the data or VM configurations inside it. Australian Consumer Law protects your hardware purchase but does not consider your data.
