All-in-one storage solution The latest addition to the Hitachi portfolio combines ultimate performance with high capacity in the same drive. The Ultrastar™ 15K600 can store 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 & 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 15K600 is designed for Hitachi reliability. The 6 Gb/s Serial Attached SCSI (SAS) & 4 Gb/s Fibre Channel Arbitrated Loop (FCAL) interfaces support the reliability required in the most demanding enterprise computing environments like on-line transaction processing, intensive data analysis, multi-user applications & data warehousing. Friends of the earth Compared to its predecessor, power usage is reduced by up to 31% to help reduce the cooling requirements in data centers. In addition, Advanced Power Management feature enables multiple idle modes in order to optimize power usage & save even more on energy costs. The 15K600 also saves money because the larger capacity enables higher data storage density in the current footprint without further expansion of the data center. These eco-friendly features qualify the 15K600 for the Eco Trac classification. Compromise nothing The Ultrastar 15K600 self-encrypting models conform to the Trusted Computing Group’s Enterprise A Security Subsystem Class encryption

The Ultrastar A7K2000 provides twice the data storage capacity of the prior generation Ultrastar A7K1000 drive, & does so using fewer watts. Operating at 7200 RPM, the Hitachi Ultrastar A7K2000 offers better overall performance than slower-RPM, capacity-oriented drives at impressively low power-consumption rates. When compared to the previous generation Ultrastar A7K1000, the A7K2000 offers up to a 155% improvement in sustained data transfer rate, & a 120% improvement in watts-per-GB. With five Advanced Power Management modes, a 36% reduction in watts during low-RPM idle mode, & using less than 1W during standby/sleep mode, the Ultrastar A7K2000 can help data centers achieve lower AC power & HVAC requirements, freeing up precious headroom for growing enterprise needs. With a robust fourth-generation mechanical design, Ultrastar A7K2000 is specifically built & tested for the enterprise. The Ultrastar SATA drive family features Hitachi-patented Rotational Vibration Safeguard (RVS) sensor technology, which optimizes drive reliability in multi-drive RAID arrays & rack-mounted systems. The Ultrastar A7K2000 demonstrates Hitachi ecological leadership with its halogen-free design & power-efficient operation. Both these features serve to qualify the drive for the Hitachi Eco Trac classification, which identifies products that minimize environmental impact in the areas of product design, manufacturing, operation & disposal. ...
