1. The warranty period starts from the purchase date as stated on the receipt of purchase.

2. Maximum sustained data transfer speed of HAT5310-18T drives.

3. Performance testing was conducted by Synology using 12 drives on an SA3600, configured using RAID 5, against similar class drives (Enterprise) with IOMeter (64KB blocks). Results are for reference only. Actual performance may vary depending on workload, testing methods, and how devices and software are configured.

4. Among the HAT5300-4T, HAT5310-8T, HAT5300-12T, HAT5300-16T, and HAT5310-18T drives, 500,000 hours of hard drive tests have been conducted with Synology devices to maximize the compatibility of these drives with Synology devices.

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.

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.
