Cross post from the Xbox One X OT, for anyone looking for a cheap external drive to have more storage for all that 4K goodness:
"Headsup GermanERA: The Western Digital store has recertified My Passport Ultra external hard drives for sale. They pop up every now and then in different storage (1 to 4 TB) and different colors.
The cherry red and the white one with 1TB are currently available for 27€ with free shipping (I at least didn't have to pay for shipping despite the store saying free shipping only starts with items 50€+). The black one is 33€. The 2 TB white drive is also up for 52€. If you don't like what's on offer right now, just bookmark the page and check back every now and then. The blue 2 TB is 35€ once on sale, unreal price.

I went with the 27€ cherry red 1TB myself, that should be more than enough for now. Btw these drives of course are recertified and you get 6 months warranty on them. Considering losing only installed game data wouldn't be as bad as losing private data due to a hardware failure, I personally don't have a problem getting a "used" external drive for my One X. Probably wouldn't do it for my PC, but in this case it should be fine.
Edit: Scratch the German only note! WD has stores in several countries. You can change the website on the top right, just choose your country and search for "recertified", you should quickly find the Passport Ultra ones.

UK link for example. Slightly more expensive at
£27 for the 1TB variant, but still a good price. Other countries all seem to have different availablities and prices, so it might be worth to check it out.
