Does SATA and SATA2 always operate on 'different channels'

[jonisaksson]

Hello

This is something I have been wondering about, not so much because I have a problem but more out of general interest.

Basically before SATA, I always made sure I had 2 hard drives both on different IDE channels and kept the OS on one and the swap file on the other harddrive to maximize performance.

Now I have got 2 SATA2 drives and I am doing the same, but my mobo has got 4 SATA2 and 4 SATA connectors, and it made me wonder if all of those 8 connectors are really on different channels?

Does anyone know how it works?

In my particular case my mobo is a DFI Lanparty UT nF4 SLI-DR Export board. But as I said I don’t see it is an issue but just hungry for more knowledge

Cheers
Jon

SATA is a point to point interconnect and all the ports are different "channels". The SATA and SATA2 are on different controllers most likely, so it would make some minuscle sense to put one drive on SATA and the other on SATA2.

I doubt that you will see any preformance difference between any combination.
