Reveeen Posted March 3, 2008 Share Posted March 3, 2008 USB devices do not have UDMA, UDMA is "Ultra Direct Memory Access", in reference to how a IDE hardrive "talks to" an IDE controller over a 80 conductor ribbon cable. The "thing" that is controlling your external hardrive speed is how it "talks" to your USB controller: how the two devices get along, the quality and length of the connecting cable, and the USB driver, all play a part. I do not have a clue about Nvidia chipset implimentation of USB, the drivers, and if it works well using Mac OS. Link to comment Share on other sites More sharing options...
