Key specifications at a glance

Designed for Synology NAS systems

This HDD is designed for NAS use and integrates with Synology hardware and DiskStation Manager (DSM). That close integration is intended to support consistent performance and simpler system management.

The drive spins at 7,200 RPM and has a 1,024 MB buffer. These specifications suit storage environments where multiple users access files.

Room for expanding storage

With 20 TB of capacity, the drive can hold large collections of work files, media or backups. It uses a standard 3.5-inch form factor and a SATA III interface, so check that your NAS accepts both before ordering.

Built for sustained workloads

The workload rate limit is 550 TB per year. Use this figure to compare the drive with the amount of data your NAS writes and reads over a typical year.

Synology reports more than 500,000 hours of in-house validation testing for the HAT5300 series. This model also has a stated mean time between failures of 2,500,000 hours. These figures describe testing and reliability measures, not a guarantee of service life.
