If I were to guess, you are asking if these two parts are compatible. They appear to be.
I already got a WD my passport and I am very happy about it
Now I am planning to buy a second drive to make a "backup of the backup" and so hopefully I should reduce the risk of loosing all the data in the main backup I have on the WD my passport
This time I would like to get case + drive. Also because an integrated solution like WD my passport could make it difficult to remove the case from the drive in some cases of disc recovery, so this should be a relatively safer option. 3.5 inches (instead of smaller) 7200
