Well, I'm not very familiar with Time Machine and the impact it may have to the other work when using "only" USB 2.
another thought: once you've got your initial full backup completed, the big impact from Time Machine is not usually the transfer to the backup drive, but the analysis it does of your files to decide what needs to be backed up; in my case, even in the middle of the night every hour it finds 2-3000 files that have changed and takes 1.5 minutes, daytime it's often 4-5 minutes (spinning 750GB drive, quad i7 MBP, USB2 backup drive)
the bigger/slower your drive and the more files, and perhaps the slower the processor or the fewer cores, the more this can bog down the user experience while Time Machine does its work
(it's dumbfounding to me that the OS & services create so many file changes per hour)
