Performance and reliability are key requirements for enterprise-class hard drives. The mature design of the Ultrastar 15K147 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 15K147 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.
- 15,000 RPM enables as much as 33 percent more I/Os per second over 10,000 RPM products
- Large 16MB cache size minimizes command overhead
- Choice of Ultra320 SCSI, 4Gb/s and 2Gb/s Fibre Channel and Serial Attached SCSI (SAS) interfaces for configuration flexibility
