24IN CBL ATA133 EIDE FLAT RIB 2DV Get the performance you expect from your UDMA IDE drives by using the Ultra ATA 80-conductor ribbon cables. The high-speed UDMA interface allows host computers to send and retrieve data faster removing bottlenecks associated with system performance. You will need the next generation of IDE cable to connect the UDMA hard drives. This 40-pin, 80-conductor cable permits higher data transmission rates, reduces crosstalk, and improves signal integrity by providing 40 additional ground lines between the 40-pin IDE signal and the ground lines. Ultra ATA EIDE ribbon cables are designed for use with Ultra 133/100 and Ultra 66 drives, and backwards compatible with Ultra33, IDE/ATAPI hard drives, CD-ROMs, CD-R/CD-RWs, tape drives, zip drives, LS-120s and other IDE/ATAPI devices.
