Last year I bought a used 90GB Kingston V200 used off Craigslist. I am running my Linux installation right now off of it. At first I treated it with kid gloves and tweaked everything I knew how to tweak to reduce writes, including turned off swapping entirely-- with 16GB RAM I never touched the swapfile anyway-- reduced the swappiness system variable, etc. When I went from Mint 13 to 15 I only turned off the swapfile and it's still running like a champ, but a part of me still just doesn't trust the little darling. I decided to get a larger one to run my W7 installation on and bought an Intel 520-series 180GB one. It too has been rock solid reliable. I trust Intel more than Kingston and probably will take W7 off it and put on Linux the next time I upgrade my OS. Anyway, the gist of what I'm saying is, they've both done very well for me. I have no personal experience with OCZ but everything I've read says stay away. Samsung makes the drives that go in Macbooks, though I don't know if the 840 you can buy at retail is the exact same one as in the Apples. For anyone thinking of taking the SSD plunge, I say go ahead. I highly recommend Intel, but then I really don't boot to Windows that often these days so the the 520 gets *much* less use than my little Kingston. It's been a workhorse.
