I do not know how in the description comes to 480 Mbit / s, for USB2? But certainly not for reading SD cards. All my over 2GB big SD cards can only partially read 10-20 images, it depends. Since the larger SD cards to my knowledge only need faster readers and not another electronic / protocol etc. This adapter is therefore only up to 2GB SD card safely used. More is not promised here too, so 4Sterne and this Notice. Meanwhile, yes, the price dropped accordingly, who already have purchased tickets so small! My Sandisk 8GB class10 for only 9-EUR today from the MM, it unfortunately does not read.
