1.2 TB SAS enterprise drive

This HP 693648-B21 is a 1.2 TB 2.5 inch internal hard drive that spins at 10000 RPM and connects through a SAS 6Gb/s interface. It is supplied as a bare drive and is designed for server environments that demand sustained throughput. The maximum external transfer rate reaches 768 MBps.

Suits high-IO server workloads.

The drive targets servers handling heavy random I/O such as databases, virtualisation hosts and transactional applications. It is not suited for quiet desktop PCs, external enclosures or cold-storage archives where lower speed and larger capacity are preferred. Buyers needing silent operation or maximum terabytes per pound should look elsewhere.

SAS 6Gb/s interface dictates controller

The single specification that decides fit is the SAS 6Gb/s interface; the system must provide a compatible SAS HBA or RAID controller with the correct backplane. Without that controller the drive cannot communicate and will not function.

Questions about this item

Will this 2.5" SAS 6Gb/s drive fit in the same bay as my existing 2.5" SAS drives?

Yes, the 2.5-inch form factor matches standard 2.5-inch SAS bays and the 6Gb/s SAS interface is backward-compatible with 3Gb/s controllers.

How can I verify the 10000 RPM spindle is running correctly after installation?

Check the drive's reported rotational speed in the RAID controller BIOS or SMART data; it should show 10000 RPM and a 6Gb/s link rate.

Does the bare-drive package include a mounting tray or cables, or must I buy them separately?

The drive ships as a bare unit without tray or cables; you will need a compatible 2.5-inch SAS tray and SAS data/power cables for your server chassis.
