OK, I've got the 240GB SSD installed in my 2011 MBA now. I thought I'd post the comparison shots of performance that some of you have asked for. Interestingly, the OWC SSD (which is driven with a SandForce chipset) doesn't support TRIM. Most say it's not needed - I'm wondering if I should enable it or not. For the time being, it's off. Also interestingly, the write speed is not really different - it's the read speed that really shot up due to it being a SATA3 device. Before: Read: 259.8 MB/s Write: 244.5 MB/s After: Read: 484.6 MB/s Write: 263.6 MB/s Don't notice a huge difference in performance (they were both fast to begin with). But now I have the space to put in a 50-60GB Boot Camp partition, which is a big deal to me. Not sure yet on battery drain, but it does seem a bit warmer than before. Hope that helps. Question: Has anyone ENABLED TRIM for an OWC SSD, and has it made a difference in any way?
