Ultra ATA cables When installing a second device on either the primary or secondary controller, you must use an industry standard 80-conductor Ultra ATA cable for optimal performance. These cables have a maximum length of 18 inches and a maximum distance of six inches between the two devices for a two-drive cable. Drives operating at speeds faster than those of the Ultra ATA-33 devices require industry-standard 40pin, 80-conductor cables to maintain the highest data transfer rates possible with the improved technology. When using Ultra ATA-133, -100, -66, and -33 drives in the same system, each drive will operate at its appropriate data transfer rate. ENWW Ultra ATA cables 149
