Choosing backup storage

HDD for backups, SSD for work. Backups are write-once, read-rarely — an HDD's slower speed never matters, and you get 2TB for the price of a 500GB SSD. Buy 2× your data: versioned backups grow, so a 2TB drive comfortably protects a 1TB laptop. Automate it: a backup you must remember is a backup that won't happen — set File History or Time Machine once. Follow 3-2-1: three copies, two media types, one offsite (cloud or a drive at a relative's house). And don't toss the box — keep the drive somewhere safe, not rattling in a backpack daily.

How we pick. We prioritize proven reliability (failure rates, warranty), real-world transfer speeds, value per terabyte, and portability. Every pick has years of owner data. Commission never influences the ranking.

Frequently asked questions

For backups and media libraries, an HDD gives you far more gigabytes per dollar and speed doesn't matter. For active work — editing video or running projects directly from the drive — an SSD's speed is worth the premium.

2TB covers full-system backups plus a healthy media library for most people. Photographers and videographers should consider 4TB+. When in doubt, buy bigger — running out mid-backup is the worst time to discover you're short.

Yes for most users — a typical laptop holds 256GB–1TB of data. 2TB leaves comfortable headroom for versioned backups over time. Only large local media collections need more.

On Windows, use File History or a free tool like Macrium; on Mac, Time Machine handles it natively. Plug in the drive, set the schedule once, and forget it — the best backup is the one you never have to remember.

The verdict

For backups, buy the Seagate Portable 2TB or WD Elements 2TB — whichever is cheaper today. For speed, the WD Elements SE 2TB SSD is the value pick, and the Samsung T7 Shield is the rugged choice for life on the move.
