7mm 2.5-inch SATA laptop drive

The Seagate ST320LM010 is a 320GB 2.5-inch internal hard drive built for laptops. It spins at 7200 RPM with a 32MB cache and connects through a SATA 6.0Gb/s interface. The 7mm z-height allows installation in thin chassis designs where standard drives cannot fit.

Suits thin-laptop upgrades and self-encrypting needs

This drive fits users replacing a 7mm drive in an ultraportable or thin-and-light notebook. The self-encrypting option helps meet data-protection requirements. Buyers needing more than 320GB of capacity or the speed of a solid-state drive should consider a different storage type.

7mm height decides fit

The single specification that decides compatibility is the 7mm drive height. Systems designed for this z-height will accept the drive; bays built only for taller drives will not. Verify the laptop's drive bay clearance before purchase.
