Proxmox vs TrueNAS: Which Should You Run? (2026)
It's the question almost every new homelabber hits: should I install Proxmox or TrueNAS? They overlap enough to be confusing but are built for different jobs. Here's the honest, practical answer.
The one-line difference
Proxmox is a hypervisor — its job is running virtual machines and containers. TrueNAS is a storage OS — its job is managing ZFS pools and serving files. You can make each do a bit of the other's job, but each is clearly best at its own.
Choose Proxmox if…
- Your main goal is running lots of services — Docker apps, Home Assistant, a media stack, test VMs.
- You want to carve one mini PC into many isolated machines.
- Storage is secondary (a couple of SSDs), not a big drive array.
Choose TrueNAS if…
- Your main goal is reliable storage — backups, a media library, file shares — on a multi-drive array.
- You want ZFS's checksums, snapshots, and self-healing front-and-centre with a clean storage UI.
- You're building a dedicated NAS with CMR drives and want apps as a bonus, not the focus.
The "run both" answer (what many people end up doing)
The popular middle path: install Proxmox on the bare metal, then run TrueNAS as a VM with the drive controller passed through to it. You get Proxmox's flexibility for services and TrueNAS's ZFS for storage on one box. It's slightly more advanced (you pass through an HBA or SATA controller), but it's the best of both worlds — and exactly the kind of decision the Homelab Starter Blueprint walks you through step by step.
Hardware notes
Both want a decent chunk of RAM (ZFS loves it). Proxmox is happy on a small SSD for boot plus NVMe for VMs; TrueNAS wants a separate boot device and dedicated NAS drives for the pool. Whichever you pick, put it on a UPS — ZFS and running VMs both hate sudden power loss.
Bottom line
Services-first → Proxmox. Storage-first → TrueNAS. Want both and willing to learn a little → Proxmox with TrueNAS virtualized. Either way, start with a capable mini PC or budget server.
