Aoostar WTR Pro (Intel N100) 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 (Intel N100) (4-bay, Intel N100 (4C/4T, up to 3.4GHz, 6W)) 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 budget tier: same 4-bay chassis, N100 instead of the 5825U, ~$100 cheaper at launch.
- Single-channel RAM and one M.2 slot — if you want the full WTR Pro experience, the 5825U is the better buy.
- Drive rules identical: CMR NAS-class for RAID, check part numbers in our SMR checker.
- 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
The low-power sibling: 6W N100, single 32GB SO-DIMM. Fine for fnOS/FygoOS or TrueNAS as a 24/7 home array; the single-channel RAM and single M.2 cap the ceiling.
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.
