1TB WD Passport, partitioned 50/50 for Time machine and File storage, hanging out of the back of my Airport Extreme
1TB Seagate drive full of movies, hanging off my WDTV Live media box
1TB Seagate full size drive as cold storage backup of Files on AExtreme storage (also automatically backed up to iDrive and manually to Onedrive)
1TB WD Passport not doing anything right now
250GB Seagate drive currently contains WinClone images of my Bootcamp partition
Honorable mention to various USB sticks in my bag and keyring and around the house for random file transfers etc.
I have just realised I have too much crap....
