Synology HAS5310-12T. HDD capacity: 12 TB, HDD speed: 7200 RPM, Storage drive buffer size: 512 MB, HDD size: 3.5", Interface: SAS3
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 MTBF, 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 HD, 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.
Storage that stands the test of time
Hard drives designed for Synology
See how Synology hard drives deliver reliability, consistent performance, and simplified system management through deep hardware-software integration.
Validation
Rigorous tests and compatibility verification ensure maximum reliability on Synology systems, even while handling the most extreme workloads.
Dependable
A 2.5 million-hour MTBF, support for up to 550 TB per year workloads, and persistent write cache technology come together to safeguard data integrity.
One-click firmware upgrades
Automatic firmware update notifications and one-click installation through DSM minimize maintenance workload and reduce the chance of oversights.
Faster issue diagnostics and resolution
Deploying Synology hard drives has led to nearly 40% fewer storage-related incidents and more efficient issue resolution for our users.
