Toshiba Launches 400GB 2.5-Inch HDD

Toshiba Corporation has announced a new line-up of 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 improved levels of performance and 7,200rpm rotational speeds to the company's full range of storage capacities.

Mass production of the 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.

The MK4058GSX uses an improved read-write head and enhanced magnetic layer to boost areal density to 477Mbit/mm2 and achieve a capacity of 400GB on only two platters, the highest data density of any of Toshiba's 2.5-inch HDD. A further plus is that acoustic noise during data seek has been reduced by 2 decibels (dB). These advances are complemented by an improved energy consumption efficiency that makes the MK4058GSX approximately 20 percent more efficient than Toshiba's current MK3252GSX.

The five other drives that Toshiba has added to its line-up take full advantage of a 7,200rpm rotation speed to boost performance. Compared to the current 200GB model (MK2049GSY), the 320GB MK3254GSY improves maximum internal data transfers rate by approximately 14 percent to support high-speed processing of high volume data, meeting demand for notebook and desktop PCs offering faster performance. The 320GB drive is also 37 percent more efficient than the MK2049GSY in terms of energy consumption efficiency. All of the drives, available in a line-up of 80, 120, 160, 250 and 320GB capacities, support an optional Free Fall Sensor function, that detects a falling HDD and parks the head before impact.

All the new 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 2.5-inch HDD.
