The InterNational Committee for Information Technology Standards said it had approved the SAS, or Serial Attached SCSI (pronounced "skuzzy"), technology for the next generation of high-end hard drives. It also gave the thumbs-up to a faster version of the Fibre Channel standard for storage networks that can transfer data at a speed of 10 gigabits per second.
SAS transfers data using a smaller number of faster wire connections compared with the current version of SCSI. It's one of a host of suchthat are replacing the older "parallel" design, which runs into speed limits because of difficulties synchronizing electrical signals across a large number of wires.
"In terms of increases in speed and performance, SAS has a longer life than parallel SCSI," John Lohmeyer, chairman of the INCITS committee that developed the SAS standard, said in a statement. "Unlike parallel SCSI, data rates can be pushed higher and higher," he said.
The SAS interface could find its way into servers and storage devices allowing for faster information retrieval.
, a lower-end but increasingly powerful interface with roots in ordinary desktop computers. The SAS interface can transfer data at 3 gigabits per second, while the current Serial ATA standard allows for 1.5 gigabits per second. Upgrades are planned for both standards.
In addition, the SAS standard can allow a computer to communicate with a Serial ATA storage device.
The Fibre Channel networking standard also got a boost with a new version called 10GFC. Fibre Channel technology is used to connect high-end data storage devices to servers.
Fibre Channel currently sends data at a top speed of 2 gigabits per second. ANSI now has approved a 10gbps standard, INCITS said.
