Toshiba
is a giant global manufacturer with a large product line and several divisions.
One of its divisions, the Storage Device Division, recently released the MK1032GAX
hard disc drive, a 2.5-inch HDD with 100GB capacity hard disk. According to
Toshiba, the MK1032GAX offers the industry's highest areal density per platter,
at 83.2 gigabits per square inch while the drive's 5400 RPM motor speed, improves
system-level performance by as much as 12 percent when compared to 4200 RPM.

In order to investigate the difference between a 5400rpm HDD with 16MB buffer
and a 4200rpm HDD with 8MB buffer, we compared the Toshiba MK1032GAX with the
Fujitsu MHT2080AT. We chose to use the Fujitsu drive in this comparison due
to the fact that most notebooks have a drive similar to the Fujitsu HDD.
