I just was assembling my new computer. I purchased an EVGA nForce 750i SLI FTW Motherboard, and a Western Digital Raptor-X 150GB hard drive. My question is, can I connect the hard drive (sata1 correct?) into the SATA2 ports on the mobo? It appears it only has 4 x sata2 ports, and no sata1 ports. I wasnt aware there was a such thing as sata2 till i read through manual while assembling.
This is why the terms "SATA 1" and "SATA 2" are incorrect -- there is no such thing. Saying it as "1" and "2" implies that there are two separate standards. There are not. SATA is one standard..
ALL SATA devices are compatible with each other, by definition.
The only (rare) exception is that there are some older SATA controllers that do not support the 150/300 MB/sec autonegotiation process. For these controllers, there is a jumper on your hard drive that can be installed that forces the hard drive to operate at 150 MB/sec and skip the negotiation process.
Otherwise, if you have a SATA controller and a SATA hard drive, plug it in and it will work.
