According to an article on electronista and MacNN, storage component maker Fujitsu has announced today that it will be releasing a 2.5" notebook hard drive with an unprecedented 300 gigabyte capacity.

The new MHX2300BT series of drive will use perpendicular magnetic recording (in which drive blocks are tilted at various angles to increase density and thus storage space). The drives will spin at 4,200 RPM, although the company claims the increased density will improve speed without increasing the 1.6 watts of power needed to power the units.

Fujitsu has claimed that the new drives will ship in the first quarter of 2007 and that a less expensive 250 gigabyte model will also be offered. No set price for the 300 gigabyte model has been released to date.
