Storage price-per-terabyte rankings

This is every product we track, in one sortable table, ranked by the only number that lets you compare a 100 GB memory card against an 18 TB tape on equal terms: real cost per terabyte. Click any column heading to re-sort, filter by category or condition, and search for a specific model. The cheapest terabyte on the entire site sits at the top by default.

Cost per terabyte is simply a product’s price divided by its capacity in terabytes. It cuts straight through headline pricing and marketing — a larger drive with a scarier sticker price is often far cheaper storage than a small one. Every row links directly to a current retail offer. For the reasoning behind the ranking and how the figures are calculated, see how we test.
