Overview:
3.5" SAS HDD HAS5300
Enterprise-grade SAS HDDs for Synology systems
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.
Performance
Up to 281 MB/s sustained data transfer
Optimization
Up to 27% faster drive repair in Synology NAS
Durability
Rated for 2.5 million hours MTTF
Updates
One-click drive firmware updates through DSM
Features:
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 verification ensure maximum reliability on Synology systems, even while handling the most extreme workloads.
One-click firmware upgrades
Automatic firmware update notifications and one-click installation through DSM minimize maintenance workload and reduce the chance of oversights.
Dependable
A 2.5 million-hour MTTF, support for up to 550 TB per year workloads, and persistent write cache technology come together to safeguard data integrity.
