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 UltrastarTM 15K300
300, 147 and 73 GB | 15,000 RPM provides up to 300 GB capacity, 16 MB cache and Ultra320 SCSI, 3 Gb/s Serial Attached
Ultra320 SCSI, 3 Gb/s SAS SCSI (SAS) and 4 Gb/s Fibre Channel interfaces. These features make the Ultrastar 15K300
and 4 Gb/s FCAL 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 qualification times.
Demonstrated reliability
Key reliablility features have been built into the Ultrastar 15K300. Rotational Vibration Safe-
guard (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 fly-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.
