Easy connection via USB but little surprise on arrival taken: no default file present even though the available size is only 698 GB of the 750 so far indicated. Even by displaying hidden files / folders and known extensions, I have found absolutely nothing. Hence, there is still files but in this case, they are super hidden and the question would be: why? Either there are no files / default and in this case, there are "lies" as the size of DD (I bought two identical black-and-pink that mark the same day). Still missing 52 GB on each of these small external HDD! In total 104 GB of lost. I almost back to the Amazon but other important cases have cornered me. Aside from that, I tested these two DD and for now, no problem. Normal speed for the USB 2 or about 4 minutes for a 2.4 GB file, but, oddly, goes a little faster if I copy several files at once! Do not even achieved when the speed of light !!! The cord is exactly 52 cm from one end to the other. No information or instructions for explanation or on SD or on the presence of the second USB socket. Not even the usual precautions for this type of device! At the end of a data transfer, you have to give a very short waiting time for the machine to eject: 1 minute even for ten GB transferred. In the end, this seems to work well (or not confirm the time reliability) but it is very unfortunate that the actual size is so different from the advertised size. A small leaflet, in French, was also desirable.
