Capacity and interface

The HP AW555A is a 2 TB hard drive that uses a SAS 6 Gb/s interface and spins at 7200 RPM in a 3.5 inch form factor. It is supplied as a bare drive without a tray. The specifications list compatibility with HP StorageWorks P2000 systems.

Who it suits and who it does not

This drive is aimed at server administrators who need a 3.5 inch SAS drive for compatible HP storage arrays. Buyers whose servers or controllers only accept 2.5 inch drives cannot use this model. Buyers who require a drive with an included mounting tray should look for a different part number.

Deciding specification

The interface is SAS 6 Gb/s, so the host system must provide a SAS backplane or controller that supports this standard. A system with only a different drive interface will not be able to connect the drive.

Questions about this item

What server chassis or backplane do I need to mount this 3.5 inch SAS drive?

A 3.5 inch drive bay with a SAS 6Gb/s backplane or direct-attached SAS HBA is required for the AW555A to connect and receive power.

Will this 7200 RPM SAS drive work in my older HP StorageWorks P2000 array?

Yes, the AW555A is listed as compatible with the HP StorageWorks P2000 and will operate at the array's supported SAS 6Gb/s link speed.

How can I verify the drive is running at 7200 RPM and 6Gb/s after installation?

Check the drive's reported rotational speed and negotiated link rate in your RAID controller BIOS, SAS topology utility, or OS disk management tools.
