HP 400GB SAS Server Drive

The HP 459508-B21 is a 400GB 3.5-inch internal hard drive spinning at 10000 RPM with a SAS 3Gb/s interface. It is supplied as a bare drive and qualified by HP for server workloads where consistent data availability matters.

Suited for SAS server bays needing 10K performance

This drive fits servers and storage arrays that accept 3.5-inch SAS drives and require 10000 RPM speeds. Systems limited to slower interfaces or smaller form factors cannot use this unit. Buyers needing higher capacities or different physical sizes should look elsewhere.

SAS 3Gb/s interface determines compatibility

The drive communicates over a SAS 3Gb/s link, so the host controller or backplane must support this exact interface. Verifying that the system provides a SAS connection is the single step that confirms whether this 400GB 10000 RPM drive will function.

Questions about this item

How can I confirm the 459508-B21 is spinning at 10000 RPM after installation?

Check the drive's reported rotational speed in the server BIOS or RAID controller utility; it should show 10000 RPM for this model.

The listing says Bare Drive — does the 459508-B21 include the 3.5" tray or do I need to buy one separately?

The supplier title notes the drive comes with a tray, but packaging may vary; verify the tray is present when the box arrives.

I see only one capacity listed — is the 400GB version the only option for the 459508-B21?

Yes, this specific model number is defined as a 400GB SAS 3Gb/s drive; other capacities carry different part numbers.
