SATA vs SATA-II cabling and motherboard interface issues

Recently purchased MSI motherbaords (865PE - Neo2-P). These support SATA drives. I've read alot recently about SATA (150 mb/s) vs "SATA-II" (300 mb/s) and the improved performance, etc, etc of the SATA-II. My question is whether an SATA & SATA-II connection cables are the same, and, if not the same are they at least compatible. That is, if I am using the motherboard noted above, will I be able to plug a SATA-II drive into that motherboard with existing cables (ie, that shipped with the motherboard "SATA")? Or, will this work at all?

Although your MOBO supports SATA drives, it does not have available a SATA-II controller.  Thus, the cables are the least of your problems.  To use the SATA-II drives to full performance (if at all) you will have to add an add-in controller for the SATA-II support.  The difference will only be seen with multiple drives, but I'm sure you've read that already.

Hope this answers your question.

If you want to look at comparison reviews, look at this:

The cables are compatable although the drive would be of no benefit unless the controller is also SATA II.  So everything is also backward compatable - ie.  SATA II drive works fine with SATA controller.

If you want to read up on SATA here is a link to the standards body for it,
  http://www.sata-io.org/index.asp

Also the jump from SATA to SATA II is not very earth shattering.  The speed change is only one part of what SATA II is about - even though the drive/controller manufacturers make it sound huge.  I think I already covered some of the other stuff in the link that huntersvcs posted - hot swap, NCQ etc.

When I said NO, I meant it won't work as a SATA-II.  Congrats, kode99 - just a misinterpretation of the answer.  Basically, we meant the same thing.
