I bought the OWC 120GB Pro version for my MacBook Pro and I love it. Best upgrade I have made! Now, I want to replace the boot drive in my 2006 Mac Pro with one. I have all my data on separate drives from my OS/Applications drive, so that should be easy. My question is whether or not I need the RE version with the 28% Over Provisioning or will the Pro version with the 7% Over Provisioning be just fine? I'm not going to do a RAID, so does this make any difference? Any additional advantage to this, and is it worth the extra cost? Thanks!
