The ATA specification allows the drive to connect directly to the ISA bus on the computer. ATA transfer rate then had been developed to 133MHz/Sec and would come out with fastest rate later (please refer to Serial ATA). DMA, data transfer rate is 16.6MHz/s. Ultra DMA, data transfer rate is 16.6MHz x 2 = 33MB/s. ATA/66, data transfer rate is 16.6MHz x 4 = 66MB/s.
