Notes:

  1. Mean Time Between Failure (MTBF) is not an estimate or guarantee of product life; it is a statistical value related to mean failure rates for a large number of products and may not accurately reflect actual operation. Actual operating life of the product may be different from the MTBF.
  2. The warranty period starts from the purchase date as stated on the receipt of purchase.
  3. Maximum sustained data transfer speed of HAS5300-16T drives.
  4. 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.
  5. Among the HAS5300 series 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.
  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.
