no, & SATA3 will be 6Gb/s but it will transfer data at a constant rate & not the theoretical maximum rate (unlike SATA1)

don't know & don't care, I just call them P / S ATA

it means the data transfer rate is the theoretical maximum that could be achieved in ideal circumstances (perfect world) & only SATA1 was restricted by the burst rate with SATA2 & 3 they are the actual transfer rates achieved (3Gb/s & 6Gb/s)

Edit: anything else, just ask
