Meeting the Need for Speed: Ultra ATA
Breaking bottlenecks is our business. With CPU performance doubling every year and high-speed 32-bit bus architectures delivering bandwidths of up to 132 megabytes per second, the current ATA disk interfaces just couldn't keep up. A new standard in data transfer was needed.


Quantum met the challenge with the new Ultra ATA interface, which enables the Ultra DMA/33 protocol. Developed in conjunction with Intel Corporation, this new protocol doubles the current burst data transfer rate to 33 megabytes per secondùall without the need for termination devices, different cabling, or other hardware changes. As a result, Ultra ATA can be implemented in virtually any new system or existing PC at little or no extra cost.

With its blazingly fast data transfer rates, Ultra ATA is perfect for the new generation of advanced operating systems, real-time video, multimedia, and any Internet-based applications. In everyday applications, Ultra ATA lets users boot up their PCs and open applications in record time. It also delivers improved data integrity through improved timing margins and Cyclical Redundancy Check (CRC) data protection verification.

With support from major chipset vendors, BIOS vendors, host adapter vendors, and hard disk drive manufacturers, Ultra ATA will become the new industry standard.
