The 3.3 GB MK3303MAN had the largest storage capacity of any 2.5-inch magnetic disk unit and featured a slim 19 millimeter profile. Toshiba began shipping the unit in 1996.
As computers became more powerful, the amount of multimedia data — images, audio, and video — along with conventional text data computers handled soared. As a result, even notebooks needed the same magnetic disk unit storage capacities as desktops.
The MK3303MAN ran at 4,852 rpm, transferred data at 16.6 MB per second, had a massive 128 KB buffer memory, and boasted an average seek time of just 13 milliseconds.
Along with the MK3303MAN, Toshiba began shipping the slimmer 12.7-millimeter-profile MK2103MAV, which could store up to 2.16 GB of data.
