HPE 2 TB SAS drive for servers

Verify SAS controller and bay fit

Confirm your system has a SAS 12Gb/s controller and an available 2.5 inch drive bay. The carrier must match your chassis for proper hot-plug operation. Check that your firmware supports digitally signed drive firmware.

Enterprise build with secure erase

HPE validates each drive for 24x7 data center use with ongoing quality monitoring. Digitally signed firmware helps prevent unauthorized access to stored data. Instant Secure Erase simplifies drive repurposing or disposal while protecting data. Common carriers ensure consistency across HPE platforms.

Questions about this item

Does the P28505-B21 ship with a mounting carrier or caddy, or do I need to order one separately?

The drive is supplied as a bare 2.5" unit; HPE servers and storage systems require a compatible HPE drive carrier that must be purchased separately.

Is the 2 TB capacity the only option in this P28505-B21 line, or are larger SAS 12Gb/s 7200 RPM drives available?

This part number is fixed at 2 TB; HPE offers higher-capacity SAS 12Gb/s 7200 RPM models under different part numbers, up to 18 TB.

How does the 7200 RPM speed affect performance in a SAS 12Gb/s server array?

The 7200 RPM spindle delivers consistent sequential throughput for bulk storage and business-critical workloads while the SAS 12Gb/s interface supports dual-port redundancy in HPE platforms.
