USB3 USB2 interface ... but ... the speed SATA chip must be interfaced USB2 or something like that because despite USB3 interface flow are not in the evidence in picture: [...]
(From left to right: internal SATAII, okay rates; with 2588us3 ORICO; with another case USB3: IcyBox IB-273StU3; Test made with the same hard drive on the same USB3 port with the same cable!)
In short it is a pity and I will return it to Amazon immediately.
May look satisfactory for most customers, who probably do not account its real slow.
Very good case if it had been sold as USB2.
