Esata to usb3 cable and mirrored drives?

I would like to connect Mybook studio II by esata to my PC on USB3 .

I see there are esat to USB3 cables I can buy to do this but they say they only connect to one drive in a rack. Will it be OK  to use this type pf cable with  my mirrored drive?



This type of adapter is not supported by Western Digital, since the My Book Studio has not been tested under that configuration. Maybe some of the other users can let you know if it is possible to use it.
