Hard drives

Synology's own drives are tested against each NAS model and get firmware updates through DSM, which is why newer models list them as the supported option. HAT3300 Plus for homes and small offices; HAT5300 and HAS5300 Enterprise for 24/7 workloads.

Plus or Enterprise?

HAT3300 Plus drives (4TB to 20TB) are rated for 24/7 NAS duty in homes and small offices with a 180TB per year workload and a three-year warranty. HAT5300 and HAS5300 Enterprise drives carry a 550TB per year workload rating, a five-year warranty and are the only option Synology lists for its xs+, SA and FS models.

Why Synology-branded drives

Synology tests each drive firmware against its NAS models and delivers updates through DSM, so a drive never falls off the compatibility list. On 25-series Plus models and all rackmounts, storage pools can only be created on listed drives. Mixing capacities is fine with SHR; mixing Plus and Enterprise in one pool is not recommended.
