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.
