Hello, I ordered this product as having an old Bouzin just equipped with USB 2.0 ports, I wanted to transfer my files faster. The delivery was also longer than expected (but I was not therefore in no hurry to reproach) As to product performance I see a clear difference if I compare it to my USB 2.0 system transfer rate of about 50MB read (it probably comes from the fact that my equipment is not new) and in addition to 110MB write !!! The thing is that at the end of the transfer the estimated time remains at "5 seconds" for a while ??? (Tests performed with removable media USB 3.0 of course) If the + is the handy front Hub (ultimately I did not need the rear ports) I was careful to feed the card with the card adequate power supply present on my power supply. Overall this corresponds to my expectations. Should be tested with a USB3.0 hard disk more efficient ... Hope this helps you in your choice. Amazon
