The card works fine. CPU load low. Speed as expected.
We use the USB 3.0 interface for data backup large amounts of data to external USB drives.
Very nice to be accompanied by appropriate cable. The corresponding Y ESATA cable had to be purchased separately as not. Only an appropriate extension cord.
No cheap product and a support, which in the "reconnaissance phase" immediately competently responded by email. This is not usual in such products. 1a. There are 5 stars
