Designed to deliver the highest performance and reliability in Synology systems Unparalleled integration with DSM and Synology hardware enables HAS5300 SAS hard drives to perform reliably in enterprise environments. Faster return to peak performance Built on two decades of storage expertise, Synology HAS5300 drives include firmware optimised for mission-critical tasks. They enable Synology systems to repair degraded RAID arrays up to 27% faster than drives of similar class and capacity. Validation Rigorous testing and compliance verification ensure maximum reliability of Synology systems even for the most demanding tasks. Simplified maintenance Drive firmware updates are provided with DSM updates, making it easy for IT teams and ensuring drives are up to date with the latest firmware. Reliability An estimated time to failure of 2.5 million hours, support for workloads of up to 550TB per year and persistent write cache technology protect data integrity.
