Hi

I am up grading my system following a lightning strike. My HDDs survived the strike so will be used in the new system. The upgrade includes a new SB Gigabyte MB that has 2 x Sata3 and 4 x Sata2 ports. My question is this. Will there be any advantage in connecting my 2 x Seagate 7200.12 HDDs to the Sata3 ports in RAID0 rather than the Sata2 ports?

Thanks

Dave

Short answer: no. If they can't pump data out faster than the effective limit of Sata2, they won't benefit from the wider pipe. It's like putting an SSD in a USB 2.0 enclosure.

Note that you will have to install drivers to use the Sata3 ports - they are probably on a separate controller chip. You didn't specify which mobo, so I couldn't look it up.

The MB is a Gigabyte GA-P67A-UD4.

Then the SATA3 ports are controlled by a Marvell chip, and will require drivers that are probably on the CD that came with the motherboard. If'n you're going to install the OS on drives attaches to the Sata3 ports, you will need to load those drivers during installation.
