I have a 2.2 15 inch early 2011 MacBook pro with 500gb 7500rpm HHD. I've come round and decided I want an SSD to take full advantage of the fast graphics, processor and ram etc. so far I'm looking at: OCZ vertex 4 512gb OCZ Vertex 3 480gb Samsung 830 series 512gb I'd like to go for the vertex 4 because it's the upgrade to the 3 but I'm reading a lot about firmware updates and all that lark but I just want to get an SSD and never have to worry about it again. Does that mean the 3 is best for me right now? The Samsung is only in there because I've heard good reliability reviews on it. Thoughts?
