80 GB IDE Laptop Hard Drive

The Seagate Momentus 4200.2 ST9808210A is an 80 GB 2.5 inch internal hard drive with a 4200 RPM spindle and 8 MB cache. It connects through an IDE Ultra ATA100 / ATA-6 interface and is supplied as a bare drive in new condition.

Suits legacy notebook repairs

This drive fits older laptops and embedded equipment that require a 2.5 inch IDE Ultra ATA100 device with low power draw and 900 Gs non-operating shock tolerance. Buyers who need higher capacity, faster rotational speed or a different interface should look elsewhere because this unit is limited to 80 GB at 4200 RPM on the IDE bus.

IDE Ultra ATA100 interface decides compatibility

The single specification that determines fit is the IDE Ultra ATA100 / ATA-6 connection; the motherboard or controller must provide this exact interface for the drive to function.
