Do you mean not to mention SATA3? I meant in my original post that any SATA cable can supports 6Gbps transfer speed.

All the other wires are just ground connections. Shielding between the TX and RX pairs is part of the spec, but common sense says that thanks to differential shielding this is largely unnecessary given the voltages, physical tolerances and layout of a SATA cable.
The SATA spec currently lists no difference in cable between SATA1 and SATA3. In theory, even a very cheap 1 meter (max length) cable ought to be capable of connecting two supporting devices at the full 6.0Gb/s SATA3 speed.
