That's pretty interesting. But I couldn't find anything aboutreading speed of USB (in German) even wikipedia has only this I found everywhere:
480MBit/s USB2.0 (60MB/s reading)
1,5 Gbut/s SATA
3,0 Gbit/s SATAII/eSATAII (I'm currently Running eSATAII, Windows and everything had no Issues)

Could someone give me a site with "reading speed" comparison or confirm that it's faster? Would also cost less Power, I would get me 3x 32GB sticks if it works xD

Just found something that might help me to Understand more ?!
SataII
RPM 7.200 ~ 60 MB/s reading
RPM 10.000 ~75MB/s reading
RPM 15.000 ~80MB/s reading (I guess that's a bit low for 5.000 RPM more than 10.000?)
