Parted Magic has been able to SE every drive I've used it with except for one. That one drive was an ES drive and it was later fixed in development so you are good with Parted Magic. Also, every SSD will show as frozen if it's attached when you boot. Parted Magic will ask you to enter a sleep mode, just do it and hit your space bar to wake the system up. Go through the procedure for SE again and you are good. The longest it has ever taken to SE an SSD is about 1 minute and that was a thrashed 480GB.

As for the Barefoot 3 comment, yeah that one will be exciting as well. Hopefully OCZ has the money to spin their own silicon.
