Hi, a quick question for the experts.

I've gathered the impression that the interface technology (usb, sata, 
pata) for disk drives is really irrelevant - for a single drive - because 
disks can't deliver data fast enough to run into an interface bottleneck.

Maybe that assumption's not correct... anyway, I see an ad for a Seagate 
external 2.5" drive which uses "USB 3.0 Super-speed, up to 10x faster 
than USB 2.0".  While that's likely true about USB 3.0, isn't it 
cynically, unethically misleading about the effect on the drive's 
performance?  Or, why would Seagate supply drives with USB 3.0 technology?

I once did the numbers regarding cylinder, spin-rate, etc, but they say 
that these days those parameters are irrelevant ...
