I'm reading all over the web that the TRIM feature has finally been added to OS X Lion, which although overdue, is a GREAT addition to this OS. I have a Samsung 256gb SSD and the firmware supports TRIM. I'm running the 10.7 preview, (there's only one build that's currently been released to my knowledge) and when I go into "System Report" and look at the settings for my SSD I see Medium: SSD. TRIM: No. Is there something I have to do to enable this? I have a late 2009 Macbook Pro 2.53ghz Duo Core DDR3. I'd appreciate any help anyone can give on this topic.
