From PC World: We've seen glimmers on the horizon for some time now, but the Serial ATA International Organization (SATA-IO) has finally made official the third iteration of the serial ATA specification. SATA Revision 3.0 doubles the existing SATA 3Gb/s bandwidth to 6Gb/s, or roughly 600 MB/s, using a connector that's fully backwards-compatible with the older specification. Device manufacturers (especially motherboards) won't have to reinvent the wheel connection-wise, which should help the new specification reach full market acceptance in a short time frame.
Other features that come with the new specification include:
* A new Native Command Queuing (NCQ) streaming command to enable isochronous data transfers for bandwidth-hungry environments
