The Synology HAT5300 Enterprise Series 20TB (HAT5310-20T) is a 3.5-inch CMR hard drive engineered and validated for Synology NAS systems. Designed for businesses and IT teams running Synology RackStation and enterprise arrays, it combines 7200 RPM operation with DSM firmware updates for dependable 24/7 storage.
The drive Synology validates for its own NAS.
Why Synology NAS Owners Choose Synology Drives
Recent Synology NAS models check drives against Synology’s compatibility list, and unlisted drives can trigger warnings or limit features. Even where third-party drives work, firmware issues are harder to resolve.
The Synology HAT5300 Enterprise Series 20TB removes that uncertainty. It is tested with Synology hardware and DSM, receives firmware updates through DSM and uses CMR recording for predictable rebuilds. At 20TB per drive, it cuts the number of bays needed for the same usable capacity, which lowers power draw and simplifies Synology NAS expansion.
Full DSM Integration
Drive health, firmware updates and storage-pool management run inside Synology DSM, giving one interface for the whole storage stack.
Built for 24/7 Multi-Bay Operation
Rated for 550TB/year and 2.5 million hours MTBF, the drive is engineered for continuous operation in multi-bay Synology systems.
