Hitachi Global Storage Technologies Demos World's First SAS-12Gb/s SSD

From X-bit Labs: Hitachi Global Storage Technologies, a wholly-owned subsidiary of Western Digital company, on Tuesday announced the storage industry’s first technology demonstration of a solid-state drive that uses Serial Attached SCSI interface with 12 gigabit per second (12Gb/s) transfer speed. SAS-12Gb/s is the next performance step in the evolution of interface technology for enterprise servers and storage solutions.

One of the enterprise features of today's SAS drives is a second interface port that provides additional bandwidth to the drive. With 12Gb/s SAS on each of these ports, the drive can transmit and receive data at a rate of 12Gb/s, resulting in a total available interface bandwidth of 4.8GB/s per drive. With this speed, enterprise and cloud datacenters will be able to reduce latency by harnessing the ultra-high performance of SSDs or by improving the performance of large-scale HDD infrastructures.

HGST did not reveal any additional details about its SAS-12Gb/s solid-state drive for enterprise systems, but said that the device has passed interoperability tests with host bus adapters and expanders from both leading providers: LSI and PMC-Sierra.

“PMC’s 12Gb/s SAS protocol controllers, RAID-on-chip (RoC) controllers and expanders enable breakthrough performance and scalability for next-generation server and networked storage systems. We have been working closely with HGST on interoperability testing, and the high-performance benefits of our 12Gb/s SAS solutions, coupled with HGST’s 12Gb/s SAS drives, will enable a new generation of cutting-edge, scalable tiered storage for corporate and cloud datacenters,” said Derek Dicker, vice president of marketing for PMC’s enterprise storage division.

The demonstration of HGST's SSDs with SAS-12Gb/s interface will take place at the SCSI trade association technology showcase on May 9, 2012, in Santa Clara, California. Commercial adoption of SAS-12Gb/s will begin in 2013.
