Hi, Two days ago, I installed a OCZ Vertex 2 120 GB SSD into my MBP. It's amazingly silent and fast, but there are some issues. Since I got the SSD, my Mac is freezing every now and then. I can't do anything for like 15 seconds (I see the colored rotating ball). This is very annoying and totally defeats the purpose of having a fast SSD. UPDATE: the freezes do not happen when using Windows 7 on Bootcamp. Anyone with similar experiences? 1. Are there any ways to check what the problem is? I already verified the disk with disk utility and the disk was OK. 2. Now the stock firmware is on the SSD. Could a firmware update resolve the problem? Is it possible to do a firmware update from my Windows Bootcamp partition? 3. Also I have only 110,5 GB usable out of the 120 GB. Is this normal? I would be really happy if you can help me out!
