I am having a hard time trying to decide between the Crucial M4 and the OCZ Vertex 3, i've read some poor reviews about the Vertex but that is has good speed. And that the M4 is reliable but is slower. I was wondering if i could get your opinion on the differences if there is any.
Are you concerned about synthetic benchmarks or real world performance? I hope you are concerned with real world performance. If that is so, then there is very little performance difference between modern ssd's.
The synthetic benchmarks are called synthetic for a reason. They are not real. They do not accurately reflect real world performance. Instead they are used to grossly exaggerate minor differences that could not normally be observed.
If I could only choose between the two, then I would choose the Crucial m4.
^yep. You'll never be able to tell the difference, and the M4's historically more reliable. The Samsung 830's also a great choice.
