How to use

Install the HDD into a compatible 3.5" drive bay of a server or workstation that supports SAS/SATA interfaces. Secure the drive following the chassis manufacturer’s instructions, connect the SAS or SATA data cable and the required 5 V / 12 V power connector, then configure the drive in the system BIOS or RAID controller as needed. Initialize and format the drive using the operating system or storage management software before placing it into production.

Usage recommendations

For optimal reliability, mount the drive in a cooled, vibration-controlled enclosure and ensure firmware and storage controller drivers are up to date. Use this model for large-capacity, sequential workloads and archival applications rather than latency-sensitive random I/O-heavy databases.
