Weaknees Roamio 4 tb extern upgrade

Ok, yes, I know all the comments on using the external drive, extra point of failures, why you need this much space, etc.



I am interested to hear from anyone did the 3TB internal upgrade along with the Weaknees 4TB external drive to give a 7TB total storage. Any problems encountered? How much have you used and notice and slowness issues...



Thanks!
