HP 703267-001 is a 500GB hard disk drive for adding or replacing storage in a compatible computer. HP identifies this part number as a 500-GB, 7200-rpm hard drive; the listing for the exact part also specifies a 7mm height.
Its 7200RPM spindle speed and 500GB capacity are useful when replacing a matching drive or restoring storage to a system that uses this part. HP lists the drive separately from the hard drive hardware kit, so the bracket and screws are not identified as part of the drive itself.
