How to use

Install the HAT5310-16T into a compatible 3.5-inch drive bay on a NAS enclosure or desktop PC that supports SATA III connections. Ensure the system firmware or NAS operating system recognizes the drive and, if applicable, allow DSM to perform automatic firmware updates. Configure the drive in a suitable RAID level or as a single volume according to your redundancy and capacity needs, then format the volume using the file system supported by your NAS or operating system. Monitor drive health and SMART attributes regularly when used in continuous operation scenarios.

Recommendations

For optimal results, use this drive in Synology systems where DSM can apply firmware updates and optimizations; pair drives of the same model and capacity in RAID arrays to maintain consistent performance and reliability, and implement regular backups in addition to RAID for data protection.
