Playing catch-up with competitors Hitachi and Samsung -- both of which have begun shipping 500GB laptop drives -- Toshiba has finally announced a new 400GB high-capacity drive along with a new line-up of high-performance 7,200rpm 2.5-inch HDDs. The new 400GB drive boosts areal density to 477Mbit/s (308Gbpsi) to achieve a capacity of 400GB on just two platters and is touted as its "low-noise flagship model." The new 400GB notebook drive (MK4058GSX) is expected to hit mass production in September and will target both notebook PC and consumer electronic applications; however, the company expects to ramp up production of its higher performance 7,200rpm models of its current drives next month, including the 320GB (MK3254GSY) model and the smaller 80GB, 120GB, 160GB and 250GB capacities.

Toshiba says its MK4058GSX uses an improved read-write head and enhanced magnetic layer to boost areal density and achieve a capacity of 400GB on only two platters, the highest data density of any of Toshiba
