Just to be clear, the connectors on 1.5, 3, and 6Gb/s SATA cables (sometimes called SATA 1, 2 and 3) are all physically the same. The controller electronics on the motherboard are different.
Whether a there's any difference between a cable from the 1.5Gb SATA days and the current "SATA 3" cable, I have no idea. I use ones that promise 6Gb, and I haven't experimented with ones that don't.
6Gb SATA SSDs are supposed to be backwards compatible with 3Gb. You shouldn't avoid buying a 6Gb drive if you only have 3Gb controllers.
