Any USB drive works with a Dell laptop — there’s no proprietary lock-in — so the real choice is HDD vs. SSD and how much capacity you need per dollar. Spinning HDDs (Seagate, WD) still win on cost-per-terabyte for pure backup; portable SSDs (Samsung, SanDisk, Crucial) cost more per gigabyte but are faster and far more shock-resistant for a drive that travels with the laptop.

- Small enough to carry alongside the laptop daily
- Higher cost per GB than a spinning HDD
SanDisk Extreme Portable SSD

- Compact, lightweight body
- Carabiner loop attachment point
- Rugged rating protects against travel accidents
- Very compact and light to carry

- Password protection and hardware encryption
- Available in large capacities (up to 5TB+)

- USB 3.2 Gen 1
- Plug-and-play, no software required

- Includes 2-year Adobe Creative Cloud Photography Plan
- Simple drag-and-drop setup

- Bundled Adobe subscription adds real value for creative work

Crucial X6 Portable SSD
A budget-friendly portable SSD that undercuts the Samsung T7 and SanDisk Extreme on price while still beating any spinning HDD on speed and durability — good value for someone upgrading from an HDD without paying flagship SSD prices.
- USB 3.2 Gen 2 interface
- Compact, lightweight design
- Available in multiple capacities
- Best price-to-performance ratio among the SSDs here
- Solid-state durability at a near-HDD price point

Buying tips
- If the drive mostly sits at a desk for backups, a spinning HDD (WD Elements, Seagate Backup Plus) gives far more storage per dollar than any SSD.
- If the drive travels in a bag with the laptop daily, a portable SSD (Samsung T7, SanDisk Extreme, Crucial X6) is worth the premium — no moving parts means no data loss risk from drops.
- Check your Dell laptop’s USB ports before buying — USB 3.2 Gen 2 drives (Samsung T7) only hit their rated speeds on a matching Gen 2 port; older Dell models may cap out at Gen 1 speeds regardless of the drive.
- Whatever you buy, follow the 3-2-1 rule for anything irreplaceable — this drive is one backup, not the only backup.
