Easing migration to small form factor enterprise-class hard disk drives, Toshiba offers 2.5-inch SAS drive technology mounted in a 3.5-inch bracket. Toshiba developed the 3.5- inch bracket to enable small form factor drives to be used in legacy based 3.5-inch servers and storage enclosures.
By incorporating the MBF series 2.5-inch drive, the MBF2- LRC option features a 10,025 RPM spin speed, 6 Gb/ sec SAS interface, and the power consumption benefits normally found with small form factor drive technology. With a top storage capacity of 600GB1, the MBF2-LRC series drive matches the highest capacity point currently available within the entire 2.5 and 3.5-inch enterprise-class segments, while consuming 70 percent less power at idle and approximately one-half the active power compared to traditional 3.5-inch enterprise-class drives. In addition to the low power consumption design, the MBF2-LRC series features an enhanced power condition state technology enabling lower RPM spin speeds when not in use. The MBF2-LRC series drive is designed for storage solutions where reliability, high capacity, and performance are required, particularly mission-critical, power-conscious and data-intensive storage applications such as mid-range volume servers, mainstream storage arrays, blade, and rackmount servers
