High Capacity, 6 Gb/s SAS Interface Enterprise HDD for Mission-Critical Server and Storage Applications

The Toshiba AL13SE series of 2.5-inch 6 Gb/s SAS interface hard disk drives offer enterprise-class performance in capacities ranging from 900GB to 300GB.

The AL13SE is the first 10,000 RPM class model enterprise drive from Toshiba to achieve 900GB capacity and is also the first of Toshiba’s 10,000 RPM drives to employ a dual stage head positioning actuator that provides additional performance gains, including a 32% increase in sustained transfer rate.

Designed for even the most demanding mission-critical applications, the AL13SE series features an operating reliability rating of 2,000,000 power-on hours, a 25% increase over prior-generation drives. System compatibility is also assured through usage of the industry-standard 512 byte sector size.

The AL13SE series drive is designed to support enterprise applications where reliability, high capacity, and performance are required. Specific applications include mid-range volume servers, mainstream storage arrays, blade and rackmount servers, and other mission-critical, power-conscious, data intensive systems.



This drive is compatible with any server that accepts 2.5"x15mm (SFF) SAS drives.
