What is the difference between “UDMA” & “UATA”?
Ultra DMA (UDMA) allows host computers send and retrieve data faster, removing the bottlenecks associated with data transfers, especially during sequential operations. In addition to speed improvements, Ultra DMA delivers new data integrity capabilities to the EIDE interface. Improved timing margins and the use of CRC (Cyclical Redundancy Check), a data transfer error detection code, help to ensure the integrity of transferred data. Ultra DMA is also recognized as Ultra ATA (UATA) and Fast ATA-2. It is endorsed by the industry’s leading hard drive manufacturers, including Fujitsu, IBM, Maxtor, Quantum, Seagate, Toshiba, and Western Digital.
