Toshiba today announced the launch of a line-up of four 2.5-inch enterprise HDDs with a 10,500 RPM rotation speed. The new drives include the AL13SEB900, which offers a 900GB capacity, the industry’s highest class. An improved magnetic recording head and disk magnetic layer give the Toshiba AL13SEB900 an areal density of 856Mbit/mm2 (552Gbpsi) and realizes a 900GB capacity, the industry’s highest class. The internal transfer rate is 286 MB/s, a boost of approximately 32% against the previous generation MBF2600RC due to improved liner recording density.
The AL13SEB900 family is the first HDD series from Toshiba to employ a dual-stage head positioning actuator, which improves head positioning accuracy by approximately 30%. It achieves highly accurate tracking in a narrow tracking band, securing stable operation. Demand for 2.5-inch HDD for enterprise applications is growing, as they have a smaller footprint and overall size and consume less power than 3.5-inch drives, while offering high level processing speeds and generating less heat. Volume shipment will start in August.
