Yes, they are SATA 3. And as i said, since they switched contollers, OCZ can't be beat. For SSDs. Nothing else they make is very good. SSDs are their forte. I'd never own an OCZ PSU. It's kinda like Sony. They make great TVs, but horrible speakers/amps/radios etc.
Hmmmm....
here you go
EDIT:
OCZ Vertex 3 SSD. The only people who gave it bad customer reviews were people plugging it into SATA2 and expecting SATA3 speeds (durrrr), and a guy switching from WD Caviar Blacks in RAID to a single SSD and expecting some miracle. Caviar Blacks in RAID are difficult to surpass with a SSD, as i'm sure you know

Anyway, Newegg has 7 different OCZ SSD SATA 3's. The Agility series just came out earlier this week so not many reviews there yet.
