There are 40-wire PATA cables and 80-wire PATA cables, but they both have 40 pins on each connector. Why are there 80-wire PATA cables if there are only 40 pins connectors?
A) The 80-wire cables can also be used for SATA drives
B) The 80-wire cables are more durable
C) The 80-wire cables have reduced crosstalk between the signal wires
D) The 80-wire cables can support twice as many drives than a 40-wire cable
E) Twice the wires make all of the data twice as useful!
The answer: C) The 80-wire cables have reduced crosstalk between the signal wires
The extra wires in an 80-wire cable aren’t used to pass traffic, but they can reduce the amount of crosstalk between the signal wires. This becomes especially important as the speed increases.
