the SATA drives are all backwards compatible with SATA150(aka SATA I)

SATA II drives are more expensive per/Mb which is evident in your post

The sata1 drive are about $60 for a 160GB hard drive and the sata2 drives are $42 for a 80GB hard drive.

get whatever drives you want, they will be compatible with the card you get. You'll just get the fastest speed the slowest connecting item is.


i.e. You have SATA II hard drives and you get a SATA/SATA150 card. Everything will go SATA/SATA150 speed.

the $60 maybe more expensive but you get more hard drive space for your money....albeit at a slower speed.
