10 Best Backup Drives 2026 in the United States

The G-Technology 18TB G-DRIVE USB-C is a large-capacity desktop external hard drive that offers plenty of space for backing up huge amounts of data, making it ideal for users who need reliable, long-term storage. Its 18TB capacity means you can store thousands of photos, videos, and documents without worrying about running out of space. It connects via USB-C with USB 3.1 Gen 1, providing good data transfer speeds suitable for everyday backup tasks, though it’s not the fastest drive available if you need very high-speed transfers.

The drive’s all-aluminum enclosure gives it a sturdy and durable feel, protecting your data from everyday bumps. While it’s classified as portable, keep in mind it’s a desktop-sized 3.5-inch drive and weighs over 4 pounds, so it’s not as easy to carry around as smaller portable drives. The device supports USB Power Delivery, which can charge compatible laptops while you back up files—this is a convenient feature if you use it with a laptop.

It’s also Apple Time Machine ready, meaning Mac users can set up automatic backups easily. If you want a simple, high-capacity backup solution primarily for desktop use and especially if you use a Mac, this drive fits well. For those needing more portable or faster options, or built-in cross-platform backup software, other drives could be worth considering.
