20 GB 2.5-inch notebook drive

This 20 GB IBM drive fits 2.5-inch notebook bays with a 9 mm height. It spins at 4200 rpm and includes a 2 MB buffer. The unit measures 3.94 length by 2.76 width by 0.3 height and weighs 1.1. It suits owners replacing a failed drive in compatible legacy laptops.

Not for high-capacity or performance needs

Buyers who need more storage or faster access times should consider other options. This model does not meet modern capacity or speed requirements. Thermals, noise and power draw in normal use are consistent with a 4200 rpm notebook-class mechanism.

Questions about this item

How do I install this 9 mm 2.5 inch notebook drive, and what step is often missed?

Fit the 9 mm high 2.5 inch drive into the notebook bay, secure it with the correct screws, then attach the IDE connector; the step often missed is forgetting to set the master or slave jumper on the drive before closing the case.

What maintenance or replacement will this 4200 rpm 20 GB drive need later?

No routine maintenance is required; the drive will eventually need replacement when mechanical wear causes read errors or the 2 MB buffer can no longer mask latency, at which point a new 2.5 inch IDE drive must be sourced.
