What do you do with your computer?
The Asus ROG Raidr is an older PCI-e 2.0 x 2 ssd. Technical reviews were disappointing.
The OCZ RevoDrive 350 is an older PCI-e 2.0 x 8 ssd. It came with a quad controller with 4 ssd's. Think if it as something similar to a RAID array.
The OCZ Z Series ssd's were business enterprise drives that are no longer in production.
I maintain the ssd database listed in a sticky at the very top of this forum section. Here is the link:

Scroll down to the brands and models you are interested in and follow the links to technical reviews in English and other languages. The Asus ROG Raidr and the OCZ RevoDrive 350 are listed in the database and there are many links to reviews of those two drives.
