True, but the USB drives with more flash modules heat up slower as they spread the load.

The new smaller (but larger capacity) one's are typically 1 module or 2, thus they heat up faster.

I actually would like to see this as well, not only for squashing network congestion on poorly configured networks, but old networks.

I have also discovered another use, Newer, Smaller (as in physical size) USB drives! I have 5 different brands, that all transfer at their max speed for the first min or less, then drop to 7-15MBps depending on the USB itself, but when using a 3rd party copier that I wont mention that HAS a rate limiting feature, I was able to keep it steady at 30-45MBps depending on which USB stick it was and the copy completed much faster then burst then overheat throttle (and it is overheating, man these things get hot to the touch!)

Please CodeSector, Add the ability to limit transfer speed (rate) to TeraCopy, I once again have 2 Copy utilities and I want to go back to 1!!!
