OK, sort of a weird question. I just got a new laptop but it only has one USB 3.0 port. I'm a pretty hardcore desktop user so I really only use the laptop when I'm travelling. When I travel I also like to take photos. But, with my camera, depending on how I have it set-up, one photo can be anywhere 7-30 MB of data, generally in the low 20s. Because I'm also a belt and suspenders kind of guy, I like to back my photos up while still on the road. So, I carry a card reader and external hard drive. Both of these happen to be USB 3.0. In the past, both were plugged into USB 2.0 ports and I just dealt with the slow transfer speeds.
Now, finally to the question, since the new laptop has a 3.0 port, would it be worthwhile buying a 3.0 hub and connecting both card reader and HD to that? Will I get faster-than-2.0 transfer speeds? Or will the bus bog down with all the I/O on the one port? Would I just be better off connecting one device to the 3.0 port and the other to a 2.0 port?
