Hey guys and gals! As I am waiting for my new SSD to arrive I have been doing more and more research about SSD's. I am getting a Crucial 256GB SSD and am wondering if turning on trim is necessary. I read that trim is off by default and needs to be hacked to turn on for SSD's other than Apple's. Is this true? Or is there a setting in OSX Lion where I can turn on trim? I also read that the new Crucial M4 has garbage collection that essentially works like trim. Any suggestions would be great, thanks!
