I would suggest reinstalling your OS, and if you continue to have problems contact the manufacturer to get it replaced.

What I want to know is why it performs 80x faster just because I’ve plugged in an external drive (I’m not using the external drive… just plugging it in).

(just spotted a typo in the question that may have confused things – sorry – I’ll re-ask in a few days).

To be clear…
- Copying from the network to my internal drive… speed is 1 Mbps
- While letting that copy run, I plug in the external USB drive
- Suddenly my copy jumps to 80 Mbps

make sure to disable your Anti Virus/Spyware etc

then repeat test without USB involved

if the speed is good then hunt down the software causing the issue

or boot from a LINUX LIVECD (like knoppix) and try the copy; if the speed is good then its a software issue
