Built upon proven technology
Hitachi’s next-generation 3.5-inch 15,000 RPM hard drive delivers the performance and
reliability required for mission-critical enterprise computing environments. Leveraging the
proven system architecture and electronics of the previous generation, the Ultrastar™ 15K300
provides up to 300GB capacity, 16MB cache and Ultra320 SCSI, 3Gb/s Serial Attached
SCSI (SAS) and 4Gb/s Fibre Channel interfaces. These features make the Ultrastar 15K300
the ideal solution for demanding enterprise computing environments like online transaction
processing, intensive data analysis and other multi-user applications. The mature design of
the Ultrastar 15K300 helps to ensure shorter qualifi cation times.
Demonstrated reliability
Key reliablility features have been built into the Ultrastar 15K300. Rotational Vibration Safeguard
(RVS) technology ensures drive performance in multi-drive systems where rotational
vibration is likely to occur. Hitachi’s Thermal Fly-height Control (TFC) capability maintains
a consistent fl y-height during the read/write process ensuring a better soft error rate and
end-to-end data protection enhances error detection for optimal data integrity. Finally, Hitachi
offers the only enterprise-class hard drive utilizing a head load/unload ramp to help minimize
drive failures as a result of handling during integration.
