So i had look through lots of forum and review about these 2 SSD(Crucial M4 and Vertex 3) I read a lot about that people getting frequently BSOD, freeze, hang etc. with Vertex 3. Crucial M4 i heard lot of good review, but the Vertex 3 has a much faster speed. I want a SSD upgrade with stability with no BSOD, freeze, hang all those stuff. Please give me some advice and share me your experience. System: MacBook Pro 15" i7 2.0GHz (2011 October) 4GB RAM(Ordered 8GB to install) 500GB HDD 5400 RPM Mac OS X Lion 10.7.2 Thank You.
