Q15: What’s the real-world data transfer rate of SATA 6Gb/s?
A15: The realizable transfer rate across a 6Gb/s SATA link depends on the efficiency of the
controller design on both the host and device sides of the interconnect. The SATA 6Gb/s
interface transmits information at 600MB/s, however not all 600MB/s are realized as the user
data payload because the protocol includes other data and handshaking communications
between the host and device. In general, the SATA interface is very efficient. Realized transfer
rates are typically very close to the theoretical maximum, which is one of the primary benefits of
SATA technology for mass storage devices.
以上取自sataorg的FAQ，也可以去看SATA-IO Overview Brochure
給我的感覺SATA Revision 3.0或稱SATA 6Gb/s 應該是10bit的

一開頭介紹的(1Gigabit per second = 100 Megabytes per second)也就是理論值
SATA Rev.1 1.5G=150MB/s
SATA Rev.2 3.0G=300MB/s
SATA Rev.3 6.0G=600MB/s

老闆，我要張君雅五香海苔一包
