Cool of GBT to clearly indicate what ports we can use. Just like any other sane enthusiast, I'm keeping my board because I'm only one a single SATA port to bench.The numbering of SATA ports on a motherboard can be confusing, but once it has been explained to you it makes perfect sense. The 1st SATA port on a P67 chipset mobo is called SATA3_0 where SATA3 refers to Serial ATA 3.0 that runs at 6Gbps. If it were to read SATA2 then it refers to Serial ATA 2.0 that runs at 3Gbps. The number following the underscore (_) refers the SATA port number.
