Runs well on old hardware
“I'd take an old Xeon server with 64 GB of ECC memory, run its CPU in powersave mode, and slap TrueNAS (with ZFS) on it any day over buying a dedicated NAS”
Comment from 1 Aug 2026 in “Ten Ways NAS Is Getting Enshitified” “You don't need a lot of RAM to run TruNAS. 16gb should be sufficient unless you are planning lots of VMs.”
Comment from 24 Dec 2025 in “Build Your Own 100TB NAS in 2025: Complete TrueNAS Storage Guide” “Using an older Gaming PC you already have is actually a very good option for TrueNAS or OMV.”
Comment from 9 Mar 2026 in “My Homelab Setup” - Comment from 8 Aug 2026 in “All memory manufactured in 2027 has been sold out”
Easy web interface for ZFS
“TrueNAS made the software side trivial. It's basically plug-and-play and almost entirely configurable from the web interface.”
Comment from 27 Nov 2025 in “DIY NAS: 2026 Edition” “The nice thing about TrueNAS is that all the ZFS management stuff is nicely integrated into the UI”
Comment from 9 Mar 2026 in “My Homelab Setup” “Everything crucial to the base experience works perfectly out of the box”
Comment from 28 Nov 2025 in “DIY NAS: 2026 Edition” Fast with tuned defaults
“TrueNAS with ZFS feels faster than Open Media Vault(OMV) did on the same hardware.”
Comment from 27 Nov 2025 in “DIY NAS: 2026 Edition” “the tuned performance defaults made things a lot better for me”
Comment from 27 Nov 2025 in “DIY NAS: 2026 Edition” “it just is crazy fast, no matter what type of tasks I do”
Comment from 28 Nov 2025 in “DIY NAS: 2026 Edition” Replication, cloud sync and app support
“You can have immich on truenas that has the whole pool encrypted”
Comment from 2 Jul 2026 in “Immich v3.0.0 Released” “Truenas for example add replication, external cloud sync, gui”
Comment from 8 Jul 2026 in “How to Build a Minimal ZFS NAS Without Synology, QNAP, TrueNAS” “NAS systems running Unraid or TrueNAS with community apps”

What people warn about

Worries about company direction
“TrueNAS was major source of the myths ... because part of the company wanted you to buy their certified systems”
Comment from 19 Jun 2026 in “Ubiquiti: Enterprise NAS, Built on ZFS” “I'll admit I've still stuck with the original FreeBSD based TrueNAS, and still am kinda bummed they swapped it.”
Comment from 8 Mar 2026 in “My Homelab Setup” “I decided to stay away from truenas for my recent nas build precisely because it smelled of enshittification”
Comment from 10 Mar 2026 in “TrueNAS build system going closed source” - Comment from 9 Apr 2026 in “FreeBSD Laptop Compatibility: Top Laptops to Use with FreeBSD”

Locked-down appliance, hard to customize
“eventually you run into a bug with their (bolted on) interface and you have to dig inside the guts anyway”
Comment from 28 Nov 2025 in “DIY NAS: 2026 Edition” “It really is a locked-down appliance. Good luck installing custom software on the base OS.”
Comment from 25 Jun 2026 in “Migrating from Proxmox to NixOS and Incus” “I ended up fighting the abstraction layer way more than I benefited from it”
Comment from 31 Mar 2026 in “How to Turn Anything into a Router” Heavy features add complexity
“everything got slower, harder to maintain and even managed to somehow screw up one of my old disks when I added it to my pool”
Comment from 30 Nov 2025 in “Don't throw away your old PC–it makes a better NAS than anything you can buy” “people insist on doing truenas on top of proxmox and then introducing a networking layer between everything they do”
Comment from 8 Jul 2026 in “How to Build a Minimal ZFS NAS Without Synology, QNAP, TrueNAS” “the heavy features that came with TrueNAS' move to Linux (Kubernetes, etc.)”
