Why can't it? In benchmarks for the most part the OCZ Vertex 2 does beat an Intel G2.
In actual use you probably won't notice a difference.
As a few here have stated, Intel drives are pretty bulletproof. Basically if you are the "not sure" kind, then get the Intel because you won't stay up at night worrying whether you made the right SSD purchasing choice.
😀 LOL, I'm not sure anyone actually does that, but funny to think about since it seems as if many people posting in forums totally AGONIZE over their purchases. I don't know why? :\ It's an SSD (or CPU, or graphics card, etc.). It isn't a life or death situation and unless you crank up benchmarks, you likely won't notice a difference between one decent SSD and another, or one decent graphics card and another of the same level, or an Intel hex core versus an AMD hex core, or Corsair RAM versus G.Skill RAM... or a bunch of other choices people can't seem to make, or make out to be more than they are.
The C300 is also a good drive, but I've heard it is picky about the controller you hook it up to, plus it only works well with Windows 7 (with an OS that has Trim).
