Synology DS923+ Drive Compatibility List 2026

Best drives for the DS923+ by budget

These are all in-stock, compatible drives at last check on 24 July 2026, covering everything from a budget four-bay build to a full enterprise-grade array.

Which drive should you fit

What fits the DS923+

The DS923+ has four 3.5in SATA bays, each supporting drives up to 24TB, giving 96TB raw maximum. Because Synology's drive policy is open on this model, you're not restricted to Synology-branded drives; any CMR (conventional magnetic recording) SATA hard drive that fits the capacity ceiling will work, whether that's a NAS-optimised IronWolf, an enterprise Exos, or a WD Ultrastar. 2.5in SATA SSDs also fit the bays if you want an all-flash pool, though at these capacities per-TB cost is high compared with spinning disk, so most users reserve SSDs for the M.2 slots instead.

The two M.2 2280 NVMe slots are for read-write cache or, if you prefer, a dedicated NVMe storage pool, useful for hosting active VMs, databases, or frequently-accessed shares where SATA HDD latency becomes the bottleneck. Note that with the Ryzen R1600 dual-core processor in this unit, raw throughput ceilings exist regardless of drive choice, so NVMe mainly buys you lower latency and IOPS rather than dramatically higher sequential speeds. Any M.2 2280 NVMe SSD with a compatible connector will work given the open drive policy, though for sustained caching duty a drive rated for high write endurance (enterprise or prosumer NVMe rather than budget consumer models) will last longer under constant cache churn.
