External storage is cheap insurance against losing years of photos, documents, and projects. Choosing the right type comes down to balancing speed, durability, and capacity for your actual use case.
HDD vs. SSD for Backup
Traditional hard drives offer more storage per dollar, making them well-suited for large, infrequently accessed backups.
External SSDs are faster and more durable against drops, which matters if you’re carrying the drive around regularly.
- HDDs: more storage per dollar, better for archival backup
- SSDs: faster and more shock-resistant for portable use
- Look for at least USB 3.0 or higher for reasonable transfer speeds
- Consider drives with hardware encryption for sensitive files
Quick Buying Tips
- Follow the 3-2-1 backup rule: three copies, two media types, one offsite
- Test your backups periodically instead of assuming they’re working
- Label and date external drives if you use multiple for rotation
Frequently Asked Questions
How long do external hard drives last?
Typically 3-5 years of regular use, though this varies with handling and usage patterns.
Is cloud backup enough on its own?
It’s a great complement, but a local backup adds protection against account issues or connectivity problems.
