Hi all, I've just installed OCZ Vertex+ on my MBP mid 2009 that originally doesn't come with SSD. I managed to 'TRIM' it, but i noticed that my firmware is v3.50. Saw on OCZ website that they have v.3.55, but according to their disclaimer, no firmware update necessary if there are no operation issues with the drive. So, should i update it?My drive works fine, but i don't know what is a suitable app to gauge read/write speed for OS X.
