When preparing for our Prime Day Portable HDD deal page, I researched all the portable hard disk drive on Amazon to look for the best value-for-money one.
There are no cheaper portable HDD, on a per GB basis, at Amazon at the time of writing. This 5TB Seagate Expansion Portable sells for a mere $103.86, bringing it tantalizing close to the $20 barrier*. You won’t find a brand new, cheaper 5TB model from a recognized vendor.
