I have been having a problem with the intel 320 SSD. I had one setup as the boot drive and after a while it started to have problem such as slowdown so bad that I had to restart from. I wrote if off to a corrupt OS and did not do anything about it as I was about to get a second SSD and make a RAID 0 out of them and reformat then. Got the RAID 0 setup and right away the same problems with spinning beach balls and severe slowdowns. All the firmware is the latest. I will try to break the RAID and install the OS on the new drive and see how it does. Maybe its the older SSD having a hardware problem. I will also try to secure erase the drives with SSD Toolbox and a Windows XP Live CD. Any other ideas? I know some other people were having issues with Intel SSD RAID 0 but this started with one drive. Also I did not do a Time machine restore but a complete fresh install to eliminate corrupt files as the culprit.
