Pleasant small! Have to be ordered a Hama-extension, because the connection cable for a PC application with back-installed USB 3.o controller is of course too short. The Hama cable transmits properly and is secure. Now the object itself: For the read and write rates I used a 1.5GB file, faced with a Transcend USB Card Reader USB 2.0 for comparison. were tested 2 cards: 1 Sony Memory Stick Pro HG Duo 16GB Sandisk Extreme III and with 2 GB. The writing on the card with this product works with 20 Mbit / s, then this is probably the limit of the card; the USB stick 2.0 there were 20% less. When reading the file to the USB flash drive I arrived at max. 30 Mbit / s. At two cards, with this project were the memory stick about 45 Mbit / s and recorded on the SD card fabled 520 Mbit / s Now you can make sure his judgment itself: faster definitely than USB 2.0, but also depending on the medium.
