2nd SATA drive - does it matter which SATA port?

[pieman7]

Been using an EP-9NPA+Ultra for about a year now with 1 SATA drive plugged into SATA1 (the first port). I'm leaving the existing drive as the boot drive. I just recently got a 2nd SATA drive to use as a "D" drive. Not using RAID. Wondering if it matters which SATA port to plug 2nd drive into. Is the performance the same no matter what port is used for the 2nd drive? I noticed in the BIOS under "IDE Funtion" the options to enable/disable SATA 3/4 and SATA 1/2.

1) Does this imply that 1/2 is driven by one controller, and 3/4 are on a separate controller? Thus there is better performance using SATA ports 1 & 3?
2) Or, am I better off using SATA ports 1 & 2 and disabling SATA 3 & 4?

Thanks.

No difference providing they're all supplied direct from the motherboard chipset.

Probably same controller, 2 different channels. If you're not running RAID, there should be no performance difference.

Only reason to disable ports 3 &4 might be to free up ROM space if you have a boatload of i/o devices.
