Size:73.4 GB The seagate savvio 15k.2 drive delivers more transactional performance density than any other drive in the world because it is the highest-performing, greenest drive available for enterprise storage systems. by enabling the use of more than twice the drives per the same rack configuration as 3.5-inch 15k drives, the 2.5-inch savvio 15k.2 drive delivers more than twice the system performance. this is especially important in high-performance and blade servers demanding optimized raid performance per u. building on the savvio lineâ€™s industry-leading mtbf of 1.6 million hours, the savvio 15k.2 drive provides outstanding second-generation reliability. the savvio 15k.2 drive also offers the advanced sas 2.0 interface and operates at 6-gb/s transfer rates. sas 2.0 provides the next generation of signal and data integrity features, making sas ideally suited for use in high-end network storage applications. the sas 2.0 feature set and 6-gb/s transfer rate support larger topologies by connecting more expanders, host bus adapters and raid controllers within or across more storage arrays; by communicating over longer distances with high signal integrity; and by moving data two times faster, thereby doubling data throughput. the savvio 15k.2 drive with powertrim technology uses 70 percent less power than a 3.5-inch 15k drive for the lowest power profile of any high performance 15k mission-critical, tier-1 drive. it is 70 percent smaller than comparable 3.5-inch drives, which contributes to its lower power profile. this enables more system airflow, which results in lower cooling costs. the 2.5-inch drive advantages translate into reduced total cost of ownership to it organizations and administrators who want to optimize their data center power and performance efficiency.
