This Discounted 4TB External Drive Doesn't Need a Power Cord

It wasn't long ago that portable, USB-powered external hard drives maxed out at 2TB, but Seagate's new Backup Plus manages to double that, and you can pick one up for an all-time low $120 today. That price even includes 200GB of Microsoft OneDrive storage for two years, which is a $96 value on its own.
