As I got a dual mobo off ebuyer, the board only supports DMA-66. So I thought, hmm get a controller card. So I did, I got an Ultra ATA-133 card. So my Maxtor should be making the most of it. However wouldn't the throughput be less than if it was on the IDE channel of a ATA-133 capable motherboard, because it has to go through the PCI bus instead?
Just wondered. It does seem a bit quicker though than when I had it on the mobo!
