Since I also wanted to have a USB flash drive for addition to the connections for two external USB3 disks a port, I realized this product on of Goobay.
A simple front panel with two ports and the card with two ports at the back was perfect for my requirements.
In the product description should be as noted by some reviewers, informed that you need a four-pin power connector (à la FDD).
Mount board and panel, connect the cables, turn on the computer, Mini CD (provided) in, start Setup completed. So that is.
The transfer rate with external SSD or NAS I can not judge, but I'm with my 4TB Seagate at max. 100MB / s and with my Kingston DT G2 USB flash drive at max. 125MB / s (in each case depending on what you copy).
My rating:
++ Functionality, installation, driver involvement
++ Threaded nuts on the front panel (screws can be easily and precisely screw)
++ Workmanship (aperture on the card is fully seated, supply and USB jacks mounted very neat and soldered)
++ Value
+ Transfer Rate tidy
I am happy top - thumbs up and 5 stars
