In an attempt to simplify things, the USB Forum has recently changed the nomenclature to indicate throughput speed–Superspeed USB 5Gbps, Superspeed USB 10Gbps, and Superspeed USB 20Gbps–because performance is a priority for most uses. Beyond that simple statement, the story gets confusing-largely because of the plethora of variations: USB 3.0, USB 3.1 Gen 1 (5Gbps, which is basically USB 3.0), USB 3.1 Gen 2 (10Gbps), and USB 3.1 Gen 2×2 (20Gbps), and now USB 3.2 and USB4. The vast majority of external drives today are USB drives. Remember, if you’re storing important data, you need a backup-online, or if the data is copious, on a second drive. Save your pennies and get one, or two of the larger drives. You may also need the extra space eventually.Īs you can see in the chart above, while the $50/1TB is the most affordable initially, it’s by far the worst deal in terms of cost per TB/GB. The 1TB drive may seem like the best deal, but in terms of price per gigabyte, the 4TB and 5TB drives are far better deals. ![]()
