Enterprise NAS drive

The Synology HAT5300-16T is a 16TB enterprise-class hard drive built for Synology NAS systems. It runs at 7200 RPM with a 512MB cache to handle heavy multi-user workloads. The drive is designed for continuous 24/7 operation in compatible Synology servers.

SATA 6.0Gb/s integration

This 3.5-inch drive connects through a standard SATA 6.0Gb/s interface and fits regular drive bays. It frees administrators from manual firmware tasks by updating automatically through DSM. Tight hardware and software integration reduces compatibility friction in Synology deployments.

Sustained throughput

Sustained sequential read reaches up to 274 MB/s under load. In Synology NAS environments the drive delivers up to 23 percent faster sequential read performance compared to non-optimised drives. Validation spanning 400000 hours confirms consistent behaviour during prolonged enterprise use.
