1TB 2.5" SAS 6Gb/s Midline Drive

This HP 652749-B21-R is a refurbished 1TB laptop internal hard drive with a SAS 6Gb/s interface and 7200 RPM spindle speed. It uses a 2.5-inch form factor measuring up to 15.6 mm in height, 75.7 mm in width and 118.7 mm in length. The drive targets enterprise and midline workloads needing high transaction performance.

Suits SAS-Equipped Servers and Arrays

The drive fits systems with a SAS host adapter and a 2.5-inch bay accepting 15.6 mm height. It is not for machines that only provide a different interface or that lack a SAS host adapter, nor for ultra-thin chassis requiring a slimmer profile. Buyers needing larger capacity or a 3.5-inch form factor should consider other models.

SAS 6Gb/s Interface Decides Compatibility

The single specification that determines fit is the SAS 6Gb/s interface; the system must support this protocol to recognise the drive. Verify the controller and backplane provide SAS signalling before purchase. The 7200 RPM speed and 1TB capacity follow once the interface matches.

Questions about this item

Will the 2.5 inch form factor and 15.6 mm height fit my laptop drive bay?

The drive uses the 2.5 inch small form factor and measures 15.6 mm tall, 75.7 mm wide and 118.7 mm long; verify your bay accepts 15.6 mm drives.

What is the correct way to install the SAS 6Gb/s interface and what step is often missed?

Connect the drive to a SAS 6Gb/s host bus adapter or backplane; the step often missed is ensuring the system BIOS or RAID controller is set to SAS mode.

When will the 7200 RPM spindle motor typically need replacement?

Enterprise midline drives at 7200 RPM are rated for continuous operation; plan replacement after the manufacturer-rated annualised failure rate threshold or when SMART reallocated sectors rise.
