Do SATA port numbers matter?

[vespers_]

Hi,

I have a motherboard with 4 SATA connectors, numbered 1 through 4. I only have an HDD and optical drive to plug in. ports 1 and 2 are right under the VGA card fan and the other two ports (3and4) are above the VGA card.

Does the port number matter? I currently have the HDD and optical drive in 1 and 2, but would it make a different to have them in 3 and 4? it would clean everything up nicely to have them above the card as opposed to underneath it.

thanks!

some computers have a problem if the main drive is not connected to the first SATA port.
