Unfortunately, I am having a similar problem with my USB 2.0 drive. Unlike what everyone else is experiencing, I am getting very good rates (13.5MB/s, Elyssa) but they are slowly dropping.
For example, I am currently copying over a drive image from NTFS formatted external USB 250G "SimpleDrive" to my 1TB WD Black in my computer.. It is ~111GB. At the start of the transfer, the rate was 13.5MB/s and the ETA was 2-3 hours. Slowly, though, the transfer speed has dropped. I started this transfer 9-10 hours ago and it's still saying there is 8 hours remaining, at a speed of (1.7MB/sec).
A while ago, I also posted an issue I seem to have with transfer rates in Synaptic (I can't find it at the moment). Basically, the transfer speed would throttle itself down from 300-350kb/s to 17-50kb/s, and bounce back up every once in a while. I have DSL, and don't have this problem with ANYTHING else.
Could the two be connected? Is there some sort of resource manager that is designed to adjust to allow more system resources to be available?
