HardDriveAL13SEL900AL13SEL600AL13SEL450AL13SEL300The Toshiba AL13SEL 3.5-inch hard disk models deliver 6 Gb/sSAS interface enterprise-class performance in capacities rangingfrom 900GB1 to 300GB.The AL13SEL models use a 3.5-inch bracket to enable smallform factor drives to be used in legacy based 3.5-inch servers andstorage enclosures. By incorporating the AL13SE series 2.5-inchdrive, the AL13SEL option features a 10,500 RPM spin speed,6 Gb/sec SAS interface, and the power consumption benefitsnormally found with small form factor drive technology.The AL13SE series is the first 10,000 RPM class model enterprisedrive from Toshiba to achieve 900GB capacity and is also thefirst of Toshiba’s 10,000 RPM drives to employ a dual-stage headpositioning actuator that provides additional performance gains,including a 32% increase in sustained transfer rate.Designed for even the most demanding mission-criticalapplications, the AL13SE series features an operating reliabilityrating of 2,000,000 power-on hours2, a 25% increase over prior-generation drives. System compatibility is also assured throughusage of the industry-standard 512 byte sector size.In keeping with Toshiba’s leadership in power efficiency design,the AL13SE Series uses Supported Enhanced Power ConditionState technology to lower RPM idle speed.The AL13SEL series drive is designed to support enterpriseapplications where reliability, high capacity, and performance arerequired. Specific applications include mid-range volume servers,mainstream storage arrays, blade and rackmount servers, andother mission-critical, power-conscious, data-intensive systems.High Capacity, 6 Gb/s SASInterface Enterprise HDD forMission-Critical Server andStorage Applications10,500 RPM3.5-Inch SAS AL13SEL Series Hard Disk Driven Up to 900GB1 of Storage Capacityn Enhanced Power Condition State Technologyn 6 Gb/sec SASn 64MB Cache Buffer
