HGST Ultrastar 15K600 600GB 15K RPM SAS 6Gb/s 64MB 3.5" HDD All-in-one Storage Solution HGST 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 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 and the 15K600 is designed for HGST reliability. The 6Gb/s Serial Attached SCSI (SAS) and 4Gb/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 and 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 and 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 ecofriendly features qualify the 15K600 for the EcoTrac classification. Compromise Nothing The Ultrastar 15K600 self-encrypting models conform to the Trusted Computing Group’s Enterprise A Security Subsystem Class encryption specification. Now, customers can reduce costs associated with drive retirement and extend drive life by enabling repurposing of drives.
