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.

Notes:

  1. The warranty period starts from the purchase date as stated on the receipt of purchase.
  2. Maximum sustained data transfer speed of HAS5300-16T drives.
  3. Performance testing was conducted by Synology using 12 drives on an SA3600, configured using RAID 5 and a Btrfs file system, against similar capacity (12TB) and class (Enterprise) drives. Results are for reference only. Actual performance may vary depending on workload, testing methods, and how devices and software are configured.
  4. Among the HAS5300-8T, HAS5300-12T, and HAS5300-16T drives, over 200,000 hours of tests have been conducted on SAS-compatible Synology devices to ensure compatibility and performance expectations of these drives when used on Synology solutions.
  5. Mean Time to Failure (MTTF) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may be different from the MTTF and is affected by environmental and usage conditions.
  6. Product images are for illustrative purposes only. Actual product may appear with different labeling or housing, which do not affect the performance characteristics of the product.
