Get maximum performance from your UDMA IDE drive by using our Ultra ATA 80-conductor ribbon cable. A high-speed UDMA interface allows host computers to send and retrieve data faster by removing bottlenecks associated with system performance. This 40-pin, 80-conductor Ultra ATA133 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.Use with Ultra 66/100/133 drives; 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. Type-B cable type; connector layout has the blue connector for system, the gray connector for slave, and the black connector for master. Connector Spacing: 0-12-18in.Connector 1: One 80-conductor/40-pin IDC FemaleConnector 2: Two 80-conductor/40-pin IDC FemalePlease Note: Your burst rates may vary due to cable length, type of drive and controller used.
