I have a Vertex 3 in my 2011 MBP and it's been great for the year I've had it. I have an old 2008 aluminum MB which is basically now our backup/second computer. I am wanting to put an SSD in it, too. Ay reason why a Vertex 3 wouldn't work? It's SATAIII and the MB is SATAII. Anybody had a prblem with that? Thanks!
