We have the bag - like Amazon Deals - bought in a bundle with the WD MyPassport Studio. Theoretically, both match (if you purely the dimensions compares) The bag is but worked quite stable and is specified with external dimensions. The key, however, internal mass are not specified and are considerably lower. So is only suitable for panels that do not exceed 9 x 11.5 x just under 2 cm - above all, if one cable is purely :-)
