I have a workstation I built that is based upon the INTEL INTEL D975XBX2 Extreme Motherboard with an INTEL Core 2 X6800 CPU running @2.93GHz, 8GB of RAM with Windows 7 Ultimate 64 bit OS. I want to replace my current SATA-II Hard Disks due to capacity and age. Will my current motherboard recognize the SATA-III drives and allow the maximum data transfer advertized for the SATA III Drives? Or, do I need to buy a SATA III controller card to make use of the increased transfer speed supported by new SATA -III drives?
It should treat SATA 600MM/s drives as SATA 300MB/s drives just fine without a major performance loss. The hard drives can't even reach 300MB/s anyway, only the cache can do that and I don't think that it will make much of a difference. I've never noticed much of a difference between running my SATA 600MB/s drives on SATA 600MB/s controllers and SATA 3000MB/s controllers.
