MORE INFORMATION

Ultra DMA (also known as Ultra DMA/33 or ATA/33) is an extension of the ATA hard disk interface that theoretically allows burst data transfer rates of 33.3 megabytes (MB) per second. This is double the ATA-2/ATA-3 standard of 16.6 MB per second. Using Ultra DMA can result in a 40 percent increase in performance over the ATA-2/ATA-3 standard. The performance improvement is a result of the improved data rate of the drive itself.
