The Synology HAS5300-8T is an 8TB, 3.5-inch enterprise-grade hard drive using the SAS-3 (12 Gb/s) interface, designed for high-performance, durability, and reliability in mission-critical storage environments. Spinning at 7,200 RPM with a 256 MB cache, it delivers sustained data transfer rates around 230-241 MB/s. It is built for demanding 24/7 operation, with a Mean Time Between Failures (MTBF) of 2.5 million hours, and is rated for a workload of up to 550 TB per year. The drive includes firmware optimizations (via Synology’s DSM) to improve RAID rebuild times, persistent write cache for data integrity under power disruption, and full integration with Synology’s enterprise storage systems. Backed by a 5-year limited warranty, the HAS5300-8T combines speed, endurance, and enterprise features for large scale NAS, SAN, IP-storage, or surveillance setups.
