The Synology HAT3300-6T is a 6 TB internal hard disk drive engineered for use in Synology NAS systems. It uses a standard 3.5-inch form factor and a SATA 6 Gbit/s interface for integration into compatible storage enclosures. Designed for continuous 24/7 operation, the drive provides a reliable foundation for multi-user environments that require constant data availability. Its construction is optimized for the specific demands of network-attached storage, including file sharing and backup workflows in home office or small business deployments.

The drive operates at a spindle speed of 5400 RPM and includes a 256 MB cache to manage data flow. It achieves a sustained data transfer rate of up to 202 MB/s, which is sufficient for common NAS applications such as media hosting and centralized data storage. The unit is rated for a workload of 180 TB per year and has a Mean Time Between Failures (MTBF) of 1 million hours. It also supports S.M.A.R.T. technology for monitoring drive health and status within the Synology DiskStation Manager interface.
