The Extreme card uses Ultra DMA technology to achieve read and write speeds that are double the speed of an Ultra card. Ultra cards read and write at a maximum of 30 MB per second, except for the 2GB version which only has a 15 MB per second maximum. Extreme cards read and write at a maximum of 60 MB per second.
