not extra bandwidth, actually - the 40 wires are simply doubled (i.e. 
redundant)  so to make data transfer more reliable at higher speeds 
(iirc).  the blue is simply to indicate "this is the master - put the 
important device here!" (i.e. the hard disk).

curiously enough, i didn't realize this myself until recently, and ran 
my  udma disk off an old 40pin  cable, thus turning it in to an old 
slow disk :-(
