The super fast SATA 3.0

Speed is power and this is what SATA 3.0 delivers. With a wooping 6Gbit/s, it doubled the speed of the previous 2.0 specification. This will provide faster transfer rate and reading of files. The new specification will also pave the way of smaller storage devices in laptops. It also needs less power and adaptation for use in Ipod's is possible in the future.

SATA accounts 98% of the hard disk market and the current standard of hard disk drives. With this, motherboard manufacturers like Intel will most likely release SATA 3.0 capable motherboard soon. There is also no compatibility issue of the new specification as it is backward compatible with previous SATA versions.

Additional SATA 3.0 features:

  • SATA 3.0 also brings some other features to the table, including:
    An isochronous transfer mode (precisely analogous to the USB Isochronous mode) which uses NCQ to prioritize transfers for streaming applications like audio and video transmission
  • More NCQ management features
  • A pair of new connectors designed for 1.8" hard drives, and optical drives as thin as 7mm

There are also plan to increase the speed in the next SATA specifications to 12Gbits/s in the next 4 - 5 years.
