How to use

Install the SSD into a compatible 2.5" SAS bay in a server or workstation following the host system manufacturer’s instructions. Ensure the system BIOS/firmware and SAS controller drivers support enterprise SAS SSDs and confirm proper cooling within the chassis. Configure any required RAID, encryption, or provisioning settings through your storage controller or operating system tools before placing the drive into production.

Recommendations

For reliable operation, maintain proper airflow and ambient temperature within the specified 0–70 °C range, use supported SAS controllers, and avoid opening the drive casing. Regularly back up critical data and follow your organisation’s procedures for firmware updates and secure erase operations.
