The HAS5310 has passed 200,000 hours of testing on Synology hardware, has a Mean Time to Failure (MTTF) rating of 2.5 million hours, and a yearly workload rating of 550TB. Also featured is a storage capacity of 12TB, a SAS-3 12 Gb/s interface, a 512MB cache, and a rotational speed of 7200 rpm, all of which help to ensure uninterrupted data transfers with sustained speeds of up to 281 MB/s.

Perfect for Scalable and High-Availability Systems

Synology HAS5310 SAS hard drives are specifically developed and tested to provide tight integration with their SA, HD, and UC lines of storage systems. Enabling your applications to take full advantage of the bandwidth available, they are the ideal choice for high-capacity, mission-critical workloads that require 24/7 operation. Optimized firmware and integration with Synology's DiskStation Manager (DSM) operating system running on Synology storage solutions result in up to 19% faster RAID array repair speeds, greatly reducing the time the system spends in a degraded state.

Maximum Durability and Strong Data Protection

Rated for a 550TB per year workload with a 2.5 million hours MTBF, HAS5310 series drives are a safe and reliable choice for any critical data storage application. Persistent write cache technology bolsters data integrity protection and enhances overall write performance. Over 200,000 hours of validation and stress testing with Synology systems guarantee interoperability for each HAS5310 drive, ensuring maximum reliability on Synology solutions under even the heaviest workloads. Combined with backup and replication solutions running on Synology DSM, HAS5300 series SAS HDDs provide an additional layer of protection.

Integrated Maintenance

Using Synology drives and host systems simplifies IT deployment. HAS5310 drives are backed by Synology's limited 5-year warranty, providing you with long-term support for your entire system. Drive firmware update capabilities within DSM reduce required maintenance while increasing your systems' service availability.
