Hitachi Announces SAS 12 Gbps SSD Capable of 4.8GB/s Performance

HGST DEMONSTRATES INDUSTRY’S FIRST 12GB/S SAS SSD

SAN JOSE, Calif., May 01, 2012 (BUSINESS WIRE) — –HGST is Participating in the SCSI Trade Association Technology Showcase on May 9, 2012

HGST (formerly Hitachi Global Storage Technologies and now a Western Digital company, NYSE:WDC) today announced the storage industry’s first technology demonstration of a 12 gigabit per second (12Gb/s) SAS solid state drive (SSD), representing the next performance step in the evolution of SAS, the preferred interface technology for enterprise servers and storage solutions. HGST is participating in the 12Gb/s SAS demonstration at the SCSI Trade Association Technology Showcase on May 9, 2012, at the Hyatt Hotel in Santa Clara, Calif.

SAS SSDs and hard disk drives (HDDs), with their rich SCSI heritage, continue to be the building blocks of choice for enterprise and cloud storage. Enabling next-generation storage solutions, 12Gb/s SAS is a broadly supported industry standard as it delivers twice the throughput compared to today’s 6Gb/s SAS solutions, while maintaining established enterprise protocols and attributes. It is also backward compatible with 6Gb/s SAS for investment protection in current SAS infrastructures.

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.

“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 product marketing, HGST. “Meeting these interoperability milestones is critical when preparing the industry for the adoption of a new interface standard. We will continue to promote broad industry support for 12Gb/s SAS, including our sponsorship and participation in the SCSI Trade Association Technology Showcase on May 9.”

“Since the inception of SAS, LSI has delivered an industry-leading portfolio of SAS-based products,” said Bill Wuertz, senior vice president and general manager, RAID Storage Division, LSI Corporation. “As the preferred enterprise interface of the future, 12Gb/s SAS will be essential to unleashing the full performance potential of SSD storage solutions to help datacenters and cloud environments contend with massive data growth and accelerate application performance. With our ongoing validation processes and compatibility testing with HGST, we are paving the way for a smooth industry transition and market adoption of 12Gb/s SAS solutions by 2013.”

“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,” said Derek Dicker, vice president of marketing for PMC’s Enterprise Storage Division. “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.”

SCSI Trade Association Technology Showcase Event “Taming the Data Beast”

As the datacenter continues to explode with increasing storage complexities, cutting-edge SAS technology solutions are taking on the challenge of “Taming the Data Beast.” SAS solutions can be seen in action at this year’s SCSI Trade Association (STA) ( http://www.scsita.org ) Technology Showcase. Reservations can be made now for this free event at: http://www.scsita.org/sas-showcase-2012.html .

If I understood are they releasing sata 4?

No, 12Gbps SAS.

I know. but sata 3 is called 6gbps. every time sata number rises its speed doubles. So should this be sata 4=12gbps

SAS is Serial attached SCSI, SATA is Serial ATA. just like SCSI and ATA/IDE weren’t interoperable, neither are SAS and SATA. they are two different standards. it’s like trying to understand Chinese when all you speak is French.

I just don’t understand how they got the 4.8GB/s number. I must have missed something..

they are saying the SSD is capable of 4.8 GB/s throughput. SAS would then be an option, since it offers 12 Gbps, twice that of SATA-III at 6 Gbps. 4 ports @ 12 Gbps = 48 Gbps or 4.8 GB/s since SAS offers port aggregation among other features, including networking. SAS is enterprise level storage, mostly RAID and other server equipment. SATA is the primary standard for consumer level storage. hth

honestly i’m wondering what’s been happening with the bandwidth from all the fibre optics…
