Intel clarifies Serial ATA speeds

A representative added: "Like many other high-speed serial interfaces, Serial ATA uses an encoding scheme applied to the serial bitstream in order to ensure good properties of the bitstream, such as ensuring there are sufficient transitions to recover the clock from as well as ensure DC balance.

"The applied encoding scheme is referred to as 8b/10b and results in each 8-bit byte being encoded as a 10-bit symbol. The result is that Serial ATA has 10 bits per byte for the serial bistream and therefore the encoded data rate is one tenth of the raw bitrate or 150MB/s for gen-1 or 300MB/s for gen-2."

i always got confused w/ some websites stating 1.5gbps and others stating 15mbps… it all makes sense now
