Engineered for top performance and reliability in Synology systems
Unmatched integration with DSM and Synology hardware enable HAS5300 SAS hard drives to reliably deliver class-leading performance in enterprise deployments. HAS5300 drives have passed 200,000 hours of rigorous testing on Synology hardware, feature a 2.5M-hour MTTF, and are covered by Synology’s 5-year limited warranty.

Enterprise-ready
The HAS5300 series drives leverage the low-latency SAS protocol. When paired with high-performance and highly scalable Synology SA or UC series solutions, they ensure that mission-critical workloads always have access to dependable and fast storage.

Back to peak performance faster
Building on two decades of storage expertise, Synology HAS5300 drives run on firmware optimized for critical workloads that matter. They allow Synology systems to repair degraded RAID arrays up to 27% faster than similar-class and capacity drives.

Validation
Rigorous tests and compatibility verification4 ensure maximum reliability on Synology systems, even while handling the most extreme workloads.

Simplified maintenance
Drive firmware updates are shipped together with DSM updates, easing the burden on IT teams and ensuring your drives are always running the latest firmware versions.

Dependable
A 2.5 million-hour MTTF5, support for up to 550 TB per year workloads, and persistent write cache technology come together to safeguard data integrity.
