This is my second USB 3.0 hub (my first was from Startech.com). This one seems more consistent than the one I had previously. It also seems to work better with a native USB 3.0 connection than with an ExpressCard plugged into your laptop. Everything I use with it has its own power supply, so I can't speak to its ability to power portable hard drives. Based on what I've seen so far I would recommend this product to a friend.
