The Seagate Backup Plus 5TB portable USB 3.0 external hard drive is down to $90.50 on Amazon. At this price, it's actually less expensive than the 4TB version. The 5TB drive has never dropped this low before. It was most recently selling for around $130 and more regularly sells around $120.
The Seagate Backup Plus is one of the best hard drives out there despite having been around for a couple years now. In fact, it's still an Editor's Choice top pick at PC Mag because it's fast, simple, and easy to use. Five terabytes is also the largest iteration of this hard drive series. That's a lot of space to mess around with, and the drive works with both Mac and Windows computers without needing to reformat. It's covered by a two-year warranty.
A purchase of this drive also comes with two free months of Adobe's Creative Cloud Photography plan giving you unrestricted access to Photoshop and Lightroom.
