Capacity and interface

The Seagate Momentus ST9750420AS is a 2.5 inch laptop internal hard drive with a 750GB capacity. It connects through a SATA 3.0Gb/s interface and spins at 7200 RPM with a 16MB cache. The drive measures 9.5mm in height and fits standard notebook bays.

Upgraders and server use

This drive suits users replacing a failed laptop drive or adding storage to a compatible server chassis. Buyers who need a solid-state drive or a larger 2.5 inch capacity should look at other options. The bare-drive packaging means no cables or mounting hardware are included.

Sustained workload behaviour

Under continuous operation the 7200 RPM spindle maintains consistent throughput for sequential reads and writes. G-Force Protection parks the heads during sudden motion to protect stored data. SmartAlign technology handles 4K sector alignment without extra software. The drive is warranted by the seller for one year.

Questions about this item

Will the 2.5" 9.5mm form factor fit my laptop's drive bay?

The drive measures 2.5 inches wide with a 9.5mm height, matching the standard laptop drive bay dimensions of 100.35mm length and 69.85mm width.

Does the SATA 3.0Gb/s interface work with my older SATA 1.5Gb/s controller?

Yes, the SATA 3.0Gb/s interface is backward compatible and will operate at the 1.5Gb/s speed of your older controller.

How can I verify the 7200 RPM drive is healthy after installation?

Run a SMART self-test and check for reallocated sectors; the drive was erased to DoD 5220.22 M standard and tested good with up to 25 bad sectors noted.
