Toshiba today announced a new line-up of high performance 2.5-inch HDDs, including a low-noise flagship model that boosts areal density to 477Mbit/mm2 (308Gbpsi) to achieve a capacity of 400GB on just two platters, plus five drives that bring new levels of performance and 7,200rpm rotational speeds to the company’s full range of storage capacities. Further plus is that acoustic noise during info seek has been reduced by 2 decibels (dB), making operation nearly inaudible. As a conclusion, the new 400GB drive is ideally suited for noise-free playback of movies and music on notebook PCs and

digital products. An improved energy consumption efficiency makes the Toshiba MK4058GSX approximately 20% more efficient than Toshiba’s current top-of-the-line MK3252GSX.

Mass production of the Toshiba 400GB MK4058GSX will start from September, targeting notebook PC and consumer electronic applications. Mass production of the 7,200rpm drives will start in August. The line-up includes the 320GB MK3254GSY and models with 80, 120, 160 and 250GB capacities. All the new Toshiba drives comply with the European Union’s RoHS directive for eliminating use of six hazardous substances in electrical and electronic equipment, and the MK4058GSX is Toshiba’s first halogen-free 4 2.5-inch HDD.
