Hitachi delivers its highest-performing hard drive ever with the introduction of the Ultrastar. With average seek times as fast as 3.3 ms, average latency of 2 ms, and as much as 33 percent more in I/Os per second than its rivals, customers can access their data more quickly and efficiently. These performance characteristics of the Ultrastar make it the ideal solution for mission-critical enterprise computing environments like online transaction processing, data analysis, and other multi-user applications. Performance and reliability are key requirements for enterprise-class hard drives. The mature design of the Ultrastar ensures greater reliability, which helps enable shorter qualification times. Several key technologies are designed into Ultrastar drives to ensure high reliability, enhance performance and protect customer data. The Ultrastar incorporates Rotational Vibration Safeguard (RVS) technology to maintain drive performance in multi-drive systems where rotational vibration is likely to occur. Fluid dynamic bearing (FDB) motors deliver quieter drives with improved data integrity. Hitachi offers the only enterprise-class hard drive utilizing a head load/unload ramp which helps minimize drive failures caused by handling damage during integration.Technical Spec : Dimensions & Weight: Depth 14.6 Height 2.5 Weight 0.7 Width 10.2 Header: Compatibility PC Manufacturer IBM Server Packaged Quantity 1 Product Line Hitachi Ultrastar Storage Hard Drive Capacity Upto 147GB Connector 80 pin Centronics (SCA-2) Data Transfer Rate 320 Form Factor 3.5" x 1/3H Hard Drive Type Internal hard drive Interface Type Ultra320 SCSI Spindle Speed 10000-15000 Features : High Performance 80 PIN Centronics (SCA-2) Ultra 320 SCSI Interface Rotational Vibration Safeguard (RVS) technology Fluid dynamic bearing (FDB) motors System Requirements : 80 PIN Centronics (SCA-2) Connector Ultra320 SCSI Interface.
