You can never have enough hard drive space, especially when it’s this cheap. This Black Friday only, Amazon’s discounting a wide array of Seagate internal and external hard drives to great low prices.
You’ll want to head over to Amazon to see them all, but I suspect that the most popular items will be a 2TB portable drive for $60 (there are several colors available), or the 2TB FireCuda, which can speed up your PS4's loading times with a small amount of built-in flash storage.
