Hi seeing as I not have 3 x ATA 100 drives in my QS 2001 (2 on the ATA66 and 1 on the ATA33 Busses), I was thinking of adding an PCI ATA 133 card to speed things up a bit.

Is this going to make much difference to my overall system speed and if it does which cards are recommended? (my system disk is a Western Digital 120Gb with 8Mb Buffer)

BTW what is the difference between RAID and non-RAID cards

I really only want to spend about $100.
