The Card Reader is used to process high quality and fits perfectly with the rest of LianLi housing. He is also very fast. Had I bought it because of the USB 3.0 connection and was not disappointed. Could compete with my Sandisk UHS-1 card about 65MB / s transfer rates. Whether that is the limit of the reader or the card I can not say unfortunately, because I lack another comparison. The USB 3.0 port also works fine, but is also only looped through. Can any of a high quality card reader for internal USB 3.0 connector looks for this only warmly recommend. Would buy it back at any time.
