本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
Proton Drive stands out with Zero-access encryption — even Proton cannot read your files and Built-in photo backup from mobile. Sync.com counters with Zero-knowledge privacy and HIPAA and GDPR compliant.
Proton Drive's Achilles heel: storage amounts are small for the price — 200gb for $4/mo when google gives you 100gb for $2/mo. Sync.com's: no native document editing — you have to download files, edit locally, and re-sync every time. Pick whichever weakness you can live with.
結論
If you value zero-access encryption — even proton cannot read your files and proton mailを信頼済みで、同じzero-knowledgeアプローチでファイルも暗号化したいプライバシー第一のユーザー, go with Proton Drive. If 追加料金なしでデフォルトのzero-knowledge encryptionが欲しいプライバシー第一のチーム matters more, Sync.com is your pick. Neither is a bad choice — but one will fit your workflow better.
