With Hi-Speed SD Card (for example SanDisk Extreme III) of the card reader comes on about 20 MB / sec. Read and 19! MB / sec. . Write
In CF it reaches for me incredible 31MB / s read and 22MB / sec. Write!
The idea of bulk "packaging", ie, without cable and sales package, I find absolutely brilliant! A few suitable cable I already had from the camera and the old card readers (HAMA 35in1 and 1000in1). And the sales package I throw away anyway.
Hab just in case still ordered a few cables to it (here are very, very cheap!) And can only say this: which are black and also work with external hard drives well.
Good on the history of bulk packing, I find especially that the shipper (at the same time the manufacturer!) The saved shipping also passes here and calculated in my opinion fair.
All in all a very successful purchase! From me an absolute buy recommendation for one of the best (chönsten us, but that's a matter of taste) the card reader there are to buy!
He is sensational for the price !!!!
