There are cheaper drives with the same amount of storage, but Seagate is hoping the drive’s form factor and design will help make up the difference. Seagate’s new Ultra Slim line shows just how dense data storage can be, and does so at a reasonable price - a mere $100 for 2TB, and $70 for 1TB. And they’ve become small enough to fit in your pocket. A decade ago, most people had never heard of a terabyte. It is staggering how fast hard drive storage is evolving.
