"The two extra bits arent for error correction. They are part of the encoding algorithm that insures that a) the link is DC balanced and b) that there are signal transitions to keep the PLL in sync. Imagine
transferring a string of "00"'s.. No transitions are occuring and the PLL has no reference to stay in sync. "
Sorry my bad. Would "flow control" or "signaling bits" be a better statement?

"Well, I'm not an expert, but...isn't there a new ATA-133 standard coming out to increase the now-standard ATA-100? So really we will only be going from 133 to 150 MB/sec. Also, aren't the max sustained data transfer rates not even really reaching the ATA-66? If this is the case why do we keep increasing the pipe if we haven't even been filling the one we have? Seems like they need to start figuring out how to get the hard drives to transfer data more quickly. Am I right? "
Yes ATA133 standard was just released/implemented. Yes the max sustained transfer rate of the best IDE drive on the market is only 37.5MB/Sec (barely above ATA33, barely giving a reason for ATA66). However with ParallelATA (ATA33 to ATA133) only one drive is using that bandwidth at a time. With SerialATA multiple drives can be using that 150MB/Sec at the same time.
