For starters, TRIM is a command sent by the OS to a disk which tells what data are no longer in use and can be wiped internally. It’s a very important feature on a SSD. Without TRIM, a solid state drive is affected by a a not-so-small performance drop over time. And you don’t want this to happen.
That being said, all the recent SSDs feature idle garbage collection and can recovery the original performance automatically. Anyway, TRIM helps this process.
You know, I’m a hardware geek. One of my PCs is a Mac Pro equipped with a Crucial M4 256GB, a really fast drive. Mac OS X doesn’t let me enable TRIM on non-Apple disks. That’s disturbing. The solution? TRIM Enabler!
This software, developed by groths, modify the Mac OS’s storage kext – kernel extension – to enable TRIM on all SSDs. The latest version, 2.0, adds full support to Lion and that’s a good news for people like me and the hackintosh community.
You can download the software from here.
I haven’t tried the program yet but the feedback is quite good.
