Synology HAS5310 3.5" 20TB, 7200 RPM, 512MB, 550 WRL, SAS Hard Drive, Enterprise

The Synology HAS5310-20T is a 20 TB SAS hard drive engineered for enterprise storage systems. Its 3.5-inch form factor is designed for integration into server and NAS enclosures that require high-capacity, reliable storage for demanding workloads. Built for continuous 24/7 operation, the drive is suited for managing large-scale data pools and concurrent user access in data-center environments. It provides a stable storage foundation for organizations handling mission-critical information.

Performance is delivered through a 7200 RPM spindle speed, a 12 Gbit/s SAS interface, and a 512 MB buffer. These components facilitate sustained sequential read and write speeds of approximately 281 MB/s for efficient data throughput. The drive is constructed to support a workload rate of up to 550 TB per year and has a Mean Time Between Failures (MTBF) of 2.5 million hours. Its design prioritizes long-term durability and consistent performance for enterprise-level tasks.
