Connect two Ultra66/100/133 devices to your motherboard or host controller

A high speed UDMA interface enables host computers to send and retrieve data faster. The 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. Plus, this compact cable enables better airflow to reduce overheating, and minimizes clutter to save internal space within the CPU unit for easy movement when adding or removing hard drives, PCI cards or other adapters.Use this Ultra ATA EIDE ribbon cable with Ultra 133/100 and Ultra 66 drives; it is also 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.Connector 1: One 80-wire/40-pin IDC FemaleConnector 2: Two 80-wire/40-pin IDC FemalePlease Note: Your burst rates may vary due to cable length, type of drive and controller used.
