Intel 520, even beats the OCZ Vertex 3 MaxIOPS. But these are 120GB models. Intel does make a 60GB, but 120GB performs better, even still are 256GB.
Of the 3, Crucial (1st time I've said that!). Asychronous NAND is the slowest.
Don't go cheap, and don't go small, but get what you can afford. You won't be disappointed.
