I am trying to install CentOS 6.3 on new server that has 2xSSD and 1xHDD drives connected to mainboard's SATA ports by following order:

SSD1 -> SATA1
SSD2 -> SATA2
HDD1 -> SATA3

On the installation process CentOS shows me hard drives by this order:

/sda -> that is actually SSD2
/sdb -> HDD1
/sdc -> SSD1

It looks like CentOS assigns it randomly rather by the SATA connection order.

My question is: What the order of drives /sd* depending on? And how can I change it to be by the order it connected to SATA? Thank you in advance!
