What drives work in the Synology DS923+?
The DS923+ is a four-bay NAS taking four 3.5-inch or 2.5-inch SATA drives plus two M.2 NVMe slots, with an optional 10GbE upgrade. Use any CMR NAS drive — WD Red Plus/Pro, IronWolf, Toshiba N300. It pre-dates the 2025 drive policy, so third-party drives are unrestricted.

The Synology DS923+ is a four-bay NAS. It takes four 3.5-inch or 2.5-inch SATA drives, has two M.2 2280 NVMe slots, and accepts an optional 10GbE network card — so it can actually use fast storage.
Drive-compatibility policy for this model
The DS923+ pre-dates the 2025 drive policy and never required Synology-listed drives. Any third-party CMR NAS drive works without restriction; the compatibility list is advisory.
Recommended CMR picks
- General / home: WD Red Plus or IronWolf.
- 10GbE / business: WD Red Pro or IronWolf Pro (7200 rpm) to feed the faster network, optionally with an NVMe read/write cache.
- Bulk value: Seagate Exos.
Note the DS923+ uses an AMD Ryzen embedded CPU with no integrated graphics, so it does not hardware-transcode video — a factor for Plex, not for drive choice.
What to avoid
- SMR drives — they stall rebuilds.
- Desktop drives — not 24/7-rated.
