Well I have decided to go with the single 512gb ssd. Another question I have is what ssd should I get. The Samsung 830 or the OCZ Vertex 4. I have heard good things about the Vertex 4 and it is cheaper than the Samsung 830 on amazon but I know that OCZ has had many problems in the past and that Samsung has an outstanding track record in reliability. Is the Vertex 4 just as reliable? Is it worth buying over the Samsung 830.
Yes, larger SSD's are a bit faster because they have more underlying nand chips that can be accessed in parallel. Sort of an internal raid-0 if you will.
Today, I recommend Samsung830 series, and Intel 520 or 330 series for reliability.
They make their own nand chips and can do better testing and design control.
All the modern SSD's will perform similarly in actual usage; you would be hard pressed to tell the difference without a synthetic benchmark.
