I have the EX58 UD-4P, and I notice that there are SATA and SATA2 ports. I have one HD (640GB WD) and I'm wondering if I should plug it into the regular SATA or the SATA2 port? Is the Gigabyte SATA2 port faster for any reason?
i dont think any motherboards made since the SATA II spec was released even have SATA150 ports on it. and since you have an X58 board, i'd say there's a 100% chance that all the ports are indeed SATA II
it's just confusing nomenclature, and it's pretty much the same on all GB MOBOs: they're all electrically SATAII ports; the SATA ports are to the ICHxR; The SATA2, SATAII, or GSATAs are run by the jMicron secondary interface; they are pretty much the same, except that, if you intend to use RAID, you want to use the ICH - you'll see 10-15% better throughput.
