Purpose-built enterprise storage

The HPE P28028B21 is a 300 GB 2.5-inch internal hard drive spinning at 15000 RPM with a SAS 12Gb/s interface. It is designed for servers handling transaction processing, database workloads and high-performance computing tasks.

Capacity and headroom

The drive provides 300 GB of fast-access storage for latency-sensitive applications. The broader HPE enterprise portfolio scales to 2.4 TB when larger volumes are required, while this model suits workloads that prioritise response time over raw capacity.

Thermals, noise and power

Enterprise-class engineering targets stable operation in space-constrained data centres with efficient power use. The 12G SAS interface supports consistent throughput without excessive thermal load, helping maintain predictable performance in dense server deployments.

Questions about this item

Will the 12Gb/s SAS interface work with my existing 6Gb/s SAS backplane?

The drive uses a 12Gb/s SAS interface and will negotiate down to 6Gb/s speeds when connected to an older backplane.

How can I verify the 15000 RPM spindle speed is active after installation?

Check the drive's SMART data or system monitoring tools; they will report the current spindle speed as 15000 RPM during operation.

Does the P28028B21 ship with a drive tray or caddy, or must I order one separately?

The product is supplied as a bare 2.5-inch drive; a compatible HPE drive tray or caddy must be purchased separately for server installation.
