we keep ours on a 1 TB portable usb hard drive. we keep this in our safe and plug it into to our blu ray players, depending on which room we want to have fun in. The porn is sorted into many categories so we can easily find the right episode.
All is backed up to my laptop hard drive.
I think it is time to get a larger one though.
We get all of our porn downloaded from the net. Sex and Submission is my wife,s favorite, I get most of mine from housewife kelly or xhamster.
