Does Whole-Disk Encryption Slow Your PC? ⚛️

About this video

⚛️ Does whole-disk encryption slow your computer? You might be surprised. The bigger risk is losing access to your data if you’re not careful with your encryption keys and backups.

⚛️ Whole-disk encryption speed
Whole-disk encryption barely slows modern computers. It works imperceptibly when reading or writing files, and today’s fast CPUs and SSDs make any speed difference negligible. The real danger isn’t speed, it’s losing access. Always back up your encryption key, remember your password, and keep unencrypted backups of your files safe.
