Even though the Falcon 2 has 34nm NAND, it is slower than a Falcon 1 i.e. it is GSkill's version of the OCZ Agility. The "eco" controller it sports is just marketing
PR bollocks. It is just a newer revision of the Barefoot controller (IIRC so that it can handle 34nm NAND). Once agian expect 10 -15% hit to performance.
Vertex/Falcon 1/Torqx vs Intel X25-M gen 2....is like comparing Ford vs Chevy and saying one is better than the other. Each have their own strengths and weakness, but the end result is a kick ass drive. Some will prefer the merits of one over the other. Neither side is wrong (or right) in their choice. BOTH are great choices and you cant go wrong with either.
