Drive identity and purpose

This 480 GB 3.5-inch SATA III solid-state drive from HPE is built for servers and storage arrays that need a balanced mix of read and write IOPS. It targets database, virtualisation, cloud and transactional workloads where cost-effective endurance matters.

Sustained workload behaviour

The drive is classified as Mixed Use and engineered for greater endurance under continuous random read and write activity rather than short bursts. HPE backs the design with over 3.35 million hours of testing and qualification, and Digitally Signed Firmware helps ensure the firmware remains trusted throughout the drive's life.

Compatibility checklist

Verify that your server or array accepts a 3.5-inch SATA drive and that the backplane or controller supports SATA III signalling. Confirm the firmware ecosystem can recognise HPE Digitally Signed Firmware and that you can monitor wear with HPE SmartSSD Wear Gauge.

Questions about this item

How much power does the 3.5" SATA SSD draw during continuous operation?

The drive is designed for enterprise mixed-use workloads with power-efficient SATA III operation, and HPE qualifies it through 3.35 million hours of testing to ensure stable thermal behaviour in always-on server environments.

Which server drive bays and controllers accept this 3.5" SATA drive?

It fits standard 3.5" SATA hot-plug bays and works with any controller that supports SATA III; the digitally signed firmware guarantees compatibility with HPE Smart Array and other validated RAID controllers.

Can this 480 GB SATA SSD share a backplane with older 6 Gb SAS or SATA drives?

Yes, the SATA III interface negotiates down to 6 Gb or 3 Gb speeds automatically, so it operates alongside legacy SAS or SATA devices on the same backplane without configuration changes.
