Overview
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 Synologys 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.
5-year warranty
At Synology, we are committed to product innovation and quality. HAS5300 
drives are backed by a 5-year limited warranty that includes technical support 
and hardware replacement services to maximize your return on investment.
