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-userapplications. 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. Key reliablility features have been built into the Ultrastar 15K300. 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.


The Hitachi 0B20876 / HUS151414VLS300 is compatible with any server that accepts 3.5" LFF SAS Hard Drives.

Condition Levels Explained

The product has been built, rebuilt or repaired at the original manufacturer's factory (Note we NEVER sell 3rd party repaired items, as we do not find them to be reliable enough). Often these products are extremely close to new in condition, except that they contain at least one recycled or repaired component. Failure rates are often lower on these devices since they have been far more thoroughly tested than new items.
