What drives work in the Synology DS1522+?
The DS1522+ (a 2022 model) holds five 3.5-inch or 2.5-inch SATA drives plus two M.2 NVMe slots. Use any CMR NAS drive — WD Red Plus/Pro, IronWolf, Toshiba N300. It pre-dates Synology's 2025 drive policy, so third-party drives have always been unrestricted; no Synology-listed requirement applies.

The Synology DS1522+ is a five-bay NAS released in 2022. It takes five 3.5-inch or 2.5-inch SATA drives and has two M.2 2280 NVMe slots for cache, and it can expand with DX517 units.
Drive-compatibility policy for this model
Because the DS1522+ pre-dates the 2025 drive policy, it never carried the Synology-listed-drive requirement. Any third-party CMR NAS drive works for new storage pools without restriction — WD Red Plus/Pro, Seagate IronWolf/IronWolf Pro, Toshiba N300, or enterprise CMR drives. Synology's compatibility list is advisory here (it governs formal support and health integration), not a lock.
Recommended CMR picks
- General / home: WD Red Plus or IronWolf.
- Busy / business: WD Red Pro or IronWolf Pro.
- Bulk value: Seagate Exos or Toshiba N300.
What to avoid
- SMR drives — they can stall rebuilds on this five-bay array.
- Desktop drives — not built for 24/7 multi-bay use.
The table lists in-stock CMR drives by price per terabyte; with five bays, SHR-2 or RAID 6 is worth considering on large disks.
