SATA 3.0 released

New version unveiled

The Serial ATA International Organisation has released the SATA Revision 3.0 specification, which doubles data transfer speeds from 3Gbit/s to 6Gbit/s.

The specification was introduced last August, but has been in a comment stage. Vendors are now free to implement the specification in products, including hard-disk drives and solid-state disk storage devices.

The new specification, which is backward compatible with earlier SATA implementations, also includes a new native command queuing streaming command for isochronous data transfers between audio and video applications, and the Low Insertion Force connector for more compact 1.8-inch storage devices. It also supports connectors designed to accommodate 7mm optical disk drives, to allow for thinner and lighter notebooks.
