Toshiba Launches New 2.5-inch 7,200 RPM HDD Series
Toshiba Corporation , the pioneer in small form factor hard disk drives (HDDs), today announced a new family of high-performance 7,200RPM 2.5-inch HDDs, including a top-end drive with a half-terabyte capacity. Mass production of the series will start in October.
Toshiba’s high-performance MK5056GSYseries offers capacities of 160GB, 250GB, 320GB and 500GB for commercial and consumer notebook PCs, gaming notebooks, and tiny and all-in-one desktops. In operation, the drives deliver significant performance improvements over Toshiba’s previous generation of 7,200RPM drives. Data is transferred at 1,255Mb/s, a 23% boost, and energy consumption efficiency is raised by 28%.
Application of Toshiba’s original advanced acoustic management technology in the new double-platter MK5056GSY, the leading edge half-terabyte model, and the MK3256GSY, cuts acoustic noise during seek to 25dB, a 3dB decrease from the earlier MK3254GSY. The single-platter models, MK2556GSY and MK1656GSY, cut acoustic noise to 23dB, a 2dB decrease from the MK1654GSY, until now the quietest 7,200RPM 2.5-inch HDD. The MK5056GSY family is also compliant with the European Union’s RoHS directive and halogen free.
