Actually not bad .... 1 2

... But can be on my laptop with USB3 just do not operate properly.
A mirror of the internal hard drive to an SSD (in the ICY BOX inserted) was not possible !!!!
Through recurring Abkoppelungen the USB connection by the computer mirroring broke again with an error message.

Whether the error on the ICY-Box is located, or on the Dell laptop or on the fact that the USBs provide enough power, I do not know.

But: With another hard drive enclosure with an additional power supply through mains plug (USB 3.0 too), it then has to work without hesitation!
