Hey all.
I was doing some backing up today and noticed that an external USB drive I regularly use was slower than usual. I was thinking about it while several GBs were being transferred and realized that today I had plugged the USB through the LED Cinema Display from Apple while I usually have it always plugged in directly to the Mini.

So decided to run BlackMagic Speedtest and look at the difference, is this some kind of design flaw? I don't think I should expect a ~40% speed drop in writing and a ~20% drop in reading…

Could anyone try this out?
