Aoostar WTR Pro (Ryzen 7 5825U) hard-drive compatibility
Aoostar publishes official product specs — bay count, SATA interface, maximum capacity — rather than a per-drive compatibility list. This page mirrors the official specs for the WTR Pro (Ryzen 7 5825U) (4-bay, AMD Ryzen 7 5825U (8C/16T, up to 4.5GHz, Vega 8)) and cross-references the drives that five major vendors officially list.

Drive rules for this model
- 4× standard SATA 3.5"/2.5" drives; 2.5" fitment varies by model per the official FAQ — 3.5" is the safe array choice.
- The WTR Pro (5825U) is the enthusiast tier: $389+ barebones, sold via Aoostar's official store (AliExpress channel) and Amazon.
- No per-drive whitelist — standard SATA 3.5/2.5 drives up to the listed per-bay ceiling; for RAID pools prefer CMR NAS-class drives (check the part number in our SMR checker).
- 2.5" fitment: the official FAQ says 2.5" support varies by model — 3.5" is the safe assumption for a 4-bay array.
- OS: ships Windows 11 Pro; the community (TrueNAS SCALE, fnOS/FygoOS, Unraid) installs from the M.2 slot — use one NVMe for the OS and leave the SATA for the pool.
- For RAID / backup arrays, prefer CMR, NAS-class drives — check any drive's CMR/SMR status in our SMR/CMR checker, and size the pool with the RAID capacity calculator.

fnOS / FygoOS on this machine
x86-64 AMD platform — runs fnOS/FygoOS, TrueNAS SCALE or Unraid; ships with Windows 11, so the NAS build is a wipe+install. Aoostar's official line does not certify third-party NAS OSes (they support Windows), so OS choice is community territory — that's the whole point of this page.
Licensing for the international edition (free 3-user/4-drive tier, $49 Plus, $199 Lifetime) is covered in the FygoOS pricing guide; drive selection under ZFS/RAIDZ is in the FygoOS hard-drive guide.
Drives the other vendors officially list
Aoostar's official specs name no drive brands; the standard answer for any drive in the box is major-brand NAS-class (CMR) drives. These are the exact part numbers five vendors officially list, ranked by how many machines across Synology, QNAP, Asustor, TerraMaster and UGREEN certify them.
