It wasn’t long ago that portable, USB-powered external hard drives maxed out at 2TB, but this Seagate Backup Plus manages to double that, and you can pick one up for $104 today, within $4 of an all-time low.

We’re not sure how long this deal will last, so if you need to keep a lot of storage in your travel bag, or plugged into your game console, I’d grab this quickly.
