The Real Difference
Both offer free tiers, so the real question is what you get when you start paying.
OneDrive stands out with Deep Microsoft 365 integration and Personal Vault for sensitive files. Proton Drive counters with End-to-end encrypted file storage and sharing and Zero-access encryption — even Proton cannot read your files.
OneDrive's Achilles heel: sync client can be flaky — conflict files and mysterious sync failures still plague power users. Proton Drive's: storage amounts are small for the price — 200gb for $4/mo when google gives you 100gb for $2/mo. Pick whichever weakness you can live with.
