For configurations using multiple memory modules, Synology requires all installed modules to be identical and share the same model number. Compatible storage includes supported 3.5-inch SATA HDDs, 2.5-inch SATA SSDs and M.2 2280 NVMe SSDs. Storage drives are sold separately. Synology recommends consulting the official compatibility list before purchasing drives to ensure supported functionality and reliability. The M.2 slots support compatible SSD caching and SSD storage pools. M.2 SSD slots do not support hot swapping. Creating an M.2 SSD storage pool requires Synology-verified SSDs. Expanding the system from four to nine drive bays requires one Synology DX525 expansion unit, sold separately. Published capacity and performance figures vary according to installed drives, RAID configuration, workload and system configuration.
