Yes they are but if it is plugged into a USB 2 it won't make use of USB 3 speeds.

USB3 is backwards compatible with both USB2 and USB1. As BK_123 pointed out, you need a USB3 device plugged into a USB3 port to achieve USB3 speeds.

From what i can tell a USB3 external HDD basically just has two micro usb plugs that transfer into one fullsize USB so i would guess yes

Quite right my friend, Infact its a Type A & B connector. Toms Hardware has some good useful info on it here USB 3.0 Basics And Connectors - Three External (And Fast) USB 3.0 Drives Compared

Newegg has many different USB 3 cards for various prices. All of the brands are excellent however I have heard that Star Tech and Rosewill are among the better brands. Here is a link to their results page Newegg.com - usb 3 card . I would buy one of those for optimum performance.
