Confused by terms like SATA II, SATA Gen 2, and SATA 3Gb/s? You're not alone. With today's release (link in PDF format) of the PHY (physical layer) portion of the forthcoming SATA revision 3.0 specification (details here), SATA-IO, the trade association responsible for defining Serial ATA specifications, is trying hard to stomp out the many misidentifications of SATA specifications and features over the years.
SATA revision 3.0 doubles the speed of the current 3Gb/s version, reaching transfer speeds of 6Gb/s. So, what should you call the newest member of the SATA specifications family? According to the SATA Naming Guidelines, here's what works:

To find out how SATA-IO is also working to clear up confusion for current technologies, join us after the jump.
