Motherboards - [Answered] Difference between 40 and 80 wire ide cables. posted in the Hardware forums; Hi,
Is there really any difference between 40 and 80 wire ide cables apart from the master and slave position.
Regards, biltho...
There is a difference, the more wires allows for more speed. The 40-wire IDE cable supports a transfer speed of up to 33MB/sec, whilst the 80-wire IDE cable supports up to 100MB/sec.
