At this point, you're well aware of the "design flaw" affecting Intel's 6-series chipsets for Sandy Bridge. And if you've been keeping up with our related FAQ, you know that SATA ports 0/1 are unaffected by the bug. On Gigabyte boards, these are the two white SATA ports, which are both SATA 3.0. One way to figure out your SATA configuration is to tear off the side panel and take a peek inside, or you can download Gigabyte's new 6 Series SATA Check utility.
"To help our customers optimize SATA performance on their 6 series motherboards, Gigabyte has created an easy-to-use utility called the Gigabyte 6 Series SATA Check that tells you if the SATA ports that you are using are in fact the affected Intel PCH SATA 2.0 ports," Gigabyte said. "It also recommends that you change your SATA devices to the white SATA 3.0 ports. The utility is a simple program that will work on any 6 series chipset based motherboard, and has 3 possible scenarios that offer different advice for users to configure their SATA devices."
Gigabyte's giving off a bit of mixed signal here. The company claims its utility works with any 6-series chipset, though there's a bold disclaimer that reads "For Gigabyte motherboards only." Assuming it does work with all Sandy Bridge boards (and it should), this would be a handy utility to drop on your USB key when making housecalls -- there's no installation required, just fire it up for a software level glance at the SATA port configuration without diving inside the chassis.
