I am building my first computer and i have 2 20gig maxtor hd that i bought in an office depot deal. i just noticed that they arent the same dirves and i checked the serial # and one turned out to be the new ATA133 20gig hd and the other is a ATA100 20gig hd. My Soyo dragon plus doesnt support ATA 133 so i cannot get any benefit in speed from the ATA133 drive, but would i still be able to run raid 0? I have heard that you shouldnt run it with 2 drives unless they are identical?
