So... From what I'm reading, OSX on SSD is somehow immune from needing a trim command to manage re-writing erased data on a 'used' SSD. Is that true? Or... if I 'fill up' my SSD in OSX, would it make sense to format, install Windows 7 and let the trim clean up the SSD? Is that how it works? I don't know much about any of this so, any guidance... I just don't want my air to lose any of its 'airiness' This is my first Mac, so I'm also just expecting things to get bogged down the more I use it... Does that happen with macs also? Sorry, I'll stop changing the subject!
