Perhaps I should clarify, they're cheap and I'm sticking it into a Macbook Pro, so I'm going to be speed throttled no matter what... but reviews online seem to either be "we've bought 1000 of these and they all work great" or "died two days after I bought it, second one shot my dog, third one ran away with my wife."
Basically I'm just wondering if anyone has had a legit super-terrible experience with their drives.
I've almost exclusively bought OCZ and they have all been excellent. Not a single problem. The Vertex 4 is very likely the best SSD on the market right now since it doesn't use sandforce anymore.
What year MBP are you going to be putting it in? I recently bought a late 2008 MBP for my girlfriend and put in a spare Vertex 3 I had, and the Nvidia chipset of the MBP didn't play completely nice with the controller in the Vertex 3. Basically it saw that the SSD supported SATA III, and then downgraded the actual speed it would use down to SATA I for some reason. There is a fix for it though that worked for me. You can download a bootable linux utility that will fake the Vertex 3 as being a SATA II drive, and then the MBP utilized it to the full potential with no issues. That mouthful is probably hard to understand, but if you browse around the OCZ forums, there are a few people that complained about that issue. Overall, it was a really simple fix that took all of 5 minutes.
