I have a X-Drive Pro (vp-3310), which is a handy external laptop Hard drive enclosure. It has USB connectivity and 5 in 1 card reader. I have an 80gig(75gig) hard drive in it. Search for it on NewEgg.com, very reasonable for what you get out of it $210.00.
It can even function as a MP3 player but it doesn't have an in song fast forward/rewind.
I bought this so that when I am out and about taking pictures I can download them off the memory card, but it does qualify in the group. The other disadvantage of this config is that has the harddrive platters spinning around in it, so jarring and dropping
is a strict no-no.
