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. Here is a typical SATA port layout as seen on the GIGABYTE P67A-UD3P:
In the picture above the white ports are the two SATA3 ports (SATA3_0 and SATA3_1) that are not affected by Intel’s recent announcement. The black ports (SATA2_2 through SATA2_5) carry the risk of performance degradation over time.
The following chart shows which 6 series mobo SATA ports are risk free. There is a key below the chart that explains some of the abbreviations.
Key:
ESATA: External SATA port
GSATA: Additional SATA3 ports (GIGABYTE SATA ports)
09 Feb Update: The chart has been updated to include the GA-P67A-UD3R, as well as adding an additional SATA2 port to the GA_P65A-UD3 row.
