TrueNAS Scale vs Proxmox VE: Which Platform Should Run Your Home Lab?

The Short Answer

Use TrueNAS Scale if your primary goal is a reliable, storage-first NAS with ZFS at the core, SMB/NFS shares, and you want everything in one GUI. It can run VMs and Docker-based apps, but storage is its superpower.

Use Proxmox VE if virtualization and containers are your primary use case — running multiple VMs, LXC containers, and arbitrary workloads on the same hardware. Storage is possible (via ZFS in Proxmox or a separate TrueNAS VM), but compute is its strength.

Many home labbers run both — Proxmox on a compute node with VMs and LXCs, and TrueNAS on a dedicated storage node, often with NFS/SMB shares mounted into Proxmox.

Feature Comparison

TrueNAS Scale Deep Dive

TrueNAS Scale is built by iXsystems and based on Debian Linux with ZFS as its foundation. The "Scale" variant (as opposed to TrueNAS Core, which was FreeBSD-based) brings Linux compatibility, Docker app support, and a modern web UI.

Storage: Where TrueNAS Shines

The ZFS management in TrueNAS is genuinely excellent. Creating pools, adding datasets, configuring ACLs, enabling replication to another TrueNAS instance, and setting up automated snapshots — all of this is handled through a polished web GUI that anyone can learn without touching a terminal. For a NAS that family members might need to access settings on, this matters.

SMB shares (Windows file sharing) and NFS shares (Linux/Mac) are first-class citizens. You configure your dataset, assign permissions, enable the share type, and it just works. TrueNAS handles the Samba and NFS daemon configuration for you.

The Apps Ecosystem

TrueNAS Scale ships with a curated app catalog (Helm charts under the hood) and supports running Docker Compose-based apps via the "Custom App" feature. Popular self-hosted apps like Jellyfin, Nextcloud, and Home Assistant are one-click installs from the catalog.

The downside: the app system has had a rocky history between major TrueNAS versions. Apps have been migrated between different backends (from Kubernetes-based to Docker-based) and some users have lost app configurations during upgrades. If you rely heavily on apps, factor this in.

Virtualization in TrueNAS

TrueNAS supports KVM-based VMs through its GUI. It's functional — you can create VMs, assign storage, set up networking — but the experience isn't as polished as Proxmox. Creating a VM with GPU passthrough, custom boot orders, or advanced networking configurations requires more fiddling. VMs also compete with ZFS for RAM, which can cause pressure on a machine doing heavy storage duty.

Proxmox VE Deep Dive

Proxmox Virtual Environment is built by Proxmox Server Solutions GmbH, based in Austria. It's Debian-based with KVM for full virtualization and LXC for lightweight containers. The web UI is one of the best in open-source infrastructure tooling.

Virtualization: Proxmox's Superpower

Running VMs in Proxmox is a first-class experience. You get a full virtual machine manager with CPU/memory hot-plug, snapshots, live migration between nodes, hardware passthrough (GPU, USB, PCIe), and a clean GUI for managing all of it. Installing a new OS is as simple as uploading an ISO and clicking through a wizard.

LXC containers are where Proxmox really differentiates from TrueNAS. LXC containers are lighter than full VMs — they share the host kernel but have their own filesystem, network interface, and process space. Running Jellyfin in an LXC uses far fewer resources than running it in a VM, and Proxmox makes creating LXCs from community-built templates trivially easy.

Storage in Proxmox

Proxmox supports ZFS natively — you can create ZFS pools during installation or add them later via the GUI or CLI. However, the storage management UI is more limited than TrueNAS. Creating datasets, configuring SMB shares, and managing permissions requires either the CLI or third-party tools. This is fine for experienced Linux users but can be a pain point for those who want a GUI-driven NAS experience.

The most popular home lab approach is to connect Proxmox to a TrueNAS instance over NFS, using TrueNAS purely for storage and Proxmox purely for compute. This separation of concerns is clean and maintainable.

The Proxmox Subscription Model

Proxmox is free to download and use. The paid subscription tier ($110/year for one socket) gives you access to the enterprise-tested repository (more stable package updates) and commercial support. Without a subscription you use the "no-subscription" repo, which is slightly less conservative but works perfectly well for home labs.

The notorious "no valid subscription" popup on login is a minor annoyance easily removed with a one-line sed command.

# Remove the subscription nag popup (run on Proxmox host as root)
sed -i.bak "s/data.status !== 'Active'/false/g" \
  /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js
# Restart the web interface
systemctl restart pveproxy

Which Should You Choose?

Choose TrueNAS Scale if…

• Your primary need is a NAS with centralized file storage (Plex media, family backups, file sync)
• You want SMB/NFS shares set up through a GUI without touching a terminal
• You care about bulletproof ZFS management with automated snapshots and replication
• You're running it on dedicated hardware with 4+ drives
• You want to run a few apps (Jellyfin, Nextcloud) alongside your storage

Choose Proxmox VE if…

• You want to run multiple full VMs or LXC containers on the same hardware
• You're building a homelab with diverse workloads — gaming servers, test environments, self-hosted apps in isolation
• You want GPU passthrough for a gaming VM or AI workloads
• You're comfortable managing storage via CLI or don't need NAS-style shares
• You might want to scale to a cluster someday

Run Both (The Enthusiast Setup)

The most flexible home lab setup is running both: a Proxmox node for compute (VMs, LXC containers, Docker stacks) connected over 10GbE or gigabit to a TrueNAS node for storage (ZFS pools, SMB/NFS, automated snapshots). Proxmox mounts the NAS over NFS as a storage pool, so VMs get their disks stored on the NAS with ZFS data integrity.

Hardware Recommendations

Whether you go TrueNAS, Proxmox, or both, here's the hardware I recommend:

Used Supermicro MicroATX Server

ECC RAM support, IPMI remote management, excellent for TrueNAS. Buy used on eBay for best value.

~$150–300

Seagate IronWolf NAS 4TB HDD

NAS-rated drives built for 24/7 operation and vibration resistance. Reliable choice for ZFS pools.

~$80

ECC DDR4 RAM 32GB (2×16)

Error-correcting memory is essential for ZFS storage. Prevents silent data corruption over time.

~$70

10GbE Network Card (SFP+)

Connect your Proxmox and TrueNAS nodes at 10Gb for full-speed NFS storage. Mellanox ConnectX-3 used cards are excellent value.

~$30–50

Migrating from TrueNAS to Proxmox (or Vice Versa)

Already running one platform and thinking of switching? Here's the practical approach:

TrueNAS → Proxmox: Export your ZFS pool configuration, then import the drives into Proxmox. ZFS pools are portable — Proxmox will import them with zpool import. You'll need to recreate your SMB/NFS shares manually.

Proxmox → TrueNAS: Export VM disks as QCOW2 or raw images, back up your container data, then import onto TrueNAS. Running VMs on TrueNAS works but expect a less polished experience.

Final Thoughts

After years of running both platforms, my personal take: TrueNAS Scale is the best NAS operating system available, full stop. The ZFS management and file-sharing experience is unmatched. Proxmox is the best hypervisor for a home lab — flexible, powerful, and with a community that has solved basically every problem you'll encounter.

If you have one machine to work with and want to do everything, Proxmox is more versatile. If you have dedicated hardware for storage and want the best NAS experience possible, TrueNAS wins. If you can run both on separate hardware, that's the ultimate home lab configuration.
