Toshiba announces 320GB 2.5-inch hard disk drive
Toshiba announced the launch of nine new 2.5-inch hard disk drives (HDD) with latest advances in HDD technology. The new drives include the MK3252GSX, which achieves an industry-leading capacity of 320GB, and the MK2049GSY, which improves performance with a 7,200rpm rotational speed. Toshiba MK3252GSX uses an improved read-write head and enhanced magnetic layer to boost areal density and achieves a storage capacity of 320GB. The high-speed MK2049GSY offers a rotation speed of 7,200rpm and also integrates a large capacity 16MB buffer memory, supporting high-speed processing of large volumes of data: the drive improves the maximum internal data transfer rate by approximately 46%*2 and increases the average random access time by some 8%. Both models support an optional Free Fall Sensor function, which detects falling HDD and parks the head before it crashes.
The new Toshiba drives will provide product manufacturers with a broad line-up supporting many and diverse applications, including high density storage of multiple data sources, such as movies and digital photos, on high-end notebook PCs, and improved overall system performance from high-speed data transfers. The new drives also comply with the EU’s RoHS directive. Toshiba will mass produce the drives in turn, starting from November.
