What drives work in the Synology DS224+?
The DS224+ is a two-bay NAS that takes two 3.5-inch or 2.5-inch SATA drives (no M.2 slots). Use any CMR NAS drive: WD Red Plus, IronWolf, Toshiba N300. It pre-dates Synology's 2025 drive policy, so third-party drives are unrestricted; no Synology-listed requirement applies.

The Synology DS224+ is a two-bay NAS. It holds two 3.5-inch or 2.5-inch SATA drives and has no M.2 NVMe slots, so all storage lives on the two SATA bays.
Drive-compatibility policy for this model
The DS224+ pre-dates the 2025 drive policy and never required Synology-listed drives. Any third-party CMR NAS drive works without restriction. Synology's compatibility list is advisory.
Recommended CMR picks
- General / home: WD Red Plus or Seagate IronWolf; quiet 5400-class drives suit a two-bay desktop unit.
- Backup mirror: two matched CMR drives in SHR/RAID 1.
- Value: Toshiba N300.
What to avoid
- SMR drives (plain WD Red 2–6 TB): a two-bay mirror still rebuilds, and SMR stalls it.
- Desktop drives, not 24/7-rated.
With two bays the sensible layout is SHR or RAID 1 (one-drive redundancy) using two matched CMR drives. The table lists in-stock CMR drives by price per terabyte.
