Hitachi 450GB 15K600 SAS Hard Drive - 0B23662

The Hitachi Ultrastar 15K600 combines ultimate performance with high capacity in a single drive, storing up to 600GB of data while spinning at 15,000 RPM. That amounts to a capacity growth of 33% over its predecessor to keep pace with digital data growth and improve space efficiency in today’s data centers. At the same time, sequential performance increased by 23% compared to prior generation to keep data moving faster. The 64MB cache buffer is the largest in the industry in its class. The 6Gb/s Serial Attached SCSI (SAS) interface supports the reliability required in the most demanding enterprise computing environments like on-line transaction processing, intensive data analysis, multi-user applications and data warehousing.

Highlights

• 64 MB cache buffer -- optimizes read/write response times.
• 6Gb/s SAS -- Fast and reliable interfaces for enterprise-classapplications.
• Advanced Power Management -- lowers power consumption and saves cooling cost.
• Rotational Vibration Safeguard (RVS) -- Maintains drive performance in high rotational vibration environments and multi-drive systems.
