I read something about after enabling trim, the system does its magic when sitting powered on and idle over night... At least with Windows systems, but is that the same for LION when you enable TRIM? I'm new to this whole SSD thing. My Agility 3 in my 15 inch 2011 MBP has been flawless, but I wanted to show off the performance graphs to a coworker and I was STUNNED to see my read performance dropped to 100-170mbps in the DiskSpeedTest app, and write is under 100 (around 90-100mbps). When I first had the drive, I was running around 300-400 on both sides of the house.. Personally, I haven't noticed much of a slow down in speed, this is the fastest computer I ever owned, and even with a mechanical drive, I would probably still be saying that, the i7 Macbook Pros are just amazing. However, I'd like to know when I'm converting video in Handbrake, or saving a 4 hour DJ mix as a WAV file (about 3 gigs) that I'm getting the best performance. Anyway, I'm rambling now... Do I need to do anything after turning TRIM on to get it to re-condition my hard drive back to normal speeds?
