I got 2 of the Lexar USB3.0 card readers (1 for my PC, one for my laptop) after purchasing the Lexar 1000x CF card, because Lexar confirmed that their USB 2.0 card readers wouldn't read UDMA7 cards. I've been very impressed with the USB3.0 card reader - my laptop has USB3.0 capability but my PC doesn't, but to be quite honest I haven't seen a lot of difference in performance - the USB3.0 card reader is much faster than my old USB2.0 reader (which my husband now uses as he shoots exclusively JPEGS mainly for Ebay and for an online car club where he buys and sells lots of car stuff). I'd recommend the Lexar reader if you're having trouble with your old reader.

It ain't so much the things we don't know that get us in trouble. It's the things we know that just ain't so.
Why is this thus? What is the reason of this thusness?
