Product identity

The Toshiba MK4032GAX is a 40GB 2.5-inch laptop hard drive with a 5400 RPM spindle and 8MB cache. It uses an IDE Ultra ATA100 / ATA-6 interface and fits the standard 9.5mm drive bay found in many legacy notebooks. The bare-drive unit is intended for repair or upgrade of older systems that still rely on parallel ATA storage.

Interface limits

The IDE Ultra ATA100 / ATA-6 interface caps sustained transfer rates at 100 MB/s and requires a 44-pin connector with master/slave jumper configuration. Cable length inside a laptop chassis is restricted to a few centimetres, and the bus does not support hot-plug or native command queuing. Modern chipsets lack native IDE controllers, so this drive cannot be used in current laptops without a bridge adapter.

Deciding specification

The 40GB capacity is the single figure that determines suitability; it only accommodates lightweight operating systems and modest data sets. Buyers who need more storage for contemporary applications or media libraries will find the space insufficient. The 5400 RPM speed and 12ms average seek time deliver performance consistent with the drive's original era.
