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.
