I installed a 240 GB OCZ Agility 2 - A SandForce 1200 Controller Drive - a month ago.
Although the program I used (Carbon Copy Cloner) failed to write to the drive successfully, causing some frustration, I eventually used Disk Utility to image.
After that no problems. Don't worry about no TRIM support in OS X, the drive is fine. Do:
- turn "noatime" on
- never use any defragmenting software
- turn off "safe sleep"
It's taken my drive performance from a stock 5400 rpm HDD from 62 MB/sec to ~270 MB/sec.
Access time for everything is better. Virtual machines run way smoother. Applications launch within 3 seconds.
The drives may not last at this level more than a couple years but I'm stoked so far. You can't go back to platter drives and moving parts after this.
