Hitachi Global Storage to Demo First 12Gb/s SAS SSD

Hitachi Global Storage Technology (HGST), which was recently acquired by Western Digital, claims to be first with a demonstration of the first 12Gb/s SAS SSD. The company will be unveiling the device at the SCSI Trade Association Technology Showcase, which take place in Santa Clara on May 9.

As the name indicates, the drive is theoretically capable of transferring data at 12 Gb/s - twice the rate of current 6 Gb/s drives - which translates to a total bandwidth of 4.8 GB/s.

“We have successfully achieved interoperability between our 12Gb/s SAS drive and 12Gb/s SAS HBAs and expanders from both LSI and PMC-Sierra,” said Brendan Collins, vice president of HGST product marketing, in a prepared statement. “Meeting these interoperability milestones is critical when preparing the industry for the adoption of a new interface standard."

HGST said that it expects market adoption of 12 Gb SAS drives in 2013.

    Isn't SATA 6Gb/s 600MB/s maximum and SAS 6Gb/s equal to SATA 6Gb/s in bandwidth? So shouldn't SAS and SATA 12Gb/s be 1.2GB/s per port? It should take four such ports to hit 4.8GB/s as a theoretical maximum.

    are we talking sata 4?

    Since when does 12 Gb/s equal a total bandwidth of 4.8 GB/s? My math must be off (or someone who wrote this piece).
