    Get the cheapest.
    No real difference on mechanical drives, maybe burst rate but thats it.
    Sata III is backward compatible and should work on your board.

    The sata III has 64mb buffer, instead of 32mb of sata II. Does that mean that it is faster?

    Only if it needs it. If the HD can keep the amount buffered under 32MB, it will never use the rest.

    From everything I have found *not tested personally but will be soon* SataIII drives on SataIII controllers are actually "SLOWER" than SataII drives on SataII controllers do to overhead and the drives not being any faster to use that extra bandwidth of the port.

    Is it all compatible? Meaning can I use a III drive in a II port board and II drive in a III port board?

    so, if you have two sIII ports, two SSD's, one of which is a crucial sIII, the other a ocz vertex, the crucial will be throttled back to sII speeds? Not talking about raid...

    its on a per-port basis.

    sata III device on SATA III port = sata III speeds.

    sata II device on SATA III port = sata II speeds
