Seagate Demos 6Gbs Hard-Drive Transfer Speed

It looks like Seagate and AMD are already planning for the future for SATA drives by showing off their first tech demo of Serial ATA Revision 3.0. That is pretty much a fancy name for SATA 3. The new SATA 3 cables will feature a new transfer rate of six gigabits per second (589.09 MB/s) which is double to the speed of the current generation SATA 2 cables (288.55 MB/s).

Before you get excited though you should know that this will not double the transfer rate of data for your hard drive. Currently no Hard Drive, even the SSDs, have broke the SATA 2 288.55 MB/s data transfer cab, but some are getting close, the Intel X-25M is currently the highest at 250MB/s.

So why bother you may ask, Seagate commented by saying that usually the SATA cable technology always improves a couple of years in advance of the Hard Drives. Also the new spec also includes greater support for streaming operations in its Native Command Queue, so you can do streaming reads/writes without grinding all the rest of your operations to a halt. Even better news is the SATA 3 cables will be fully compatible with all SATA 2 products and will be out by the end of the year.
