本当の違い
Proton Drive offers a free tier while Tresorit doesn't — that matters if you're bootstrapping.
Proton Drive stands out with Zero-access encryption — even Proton cannot read your files and Built-in photo backup from mobile. Tresorit counters with Swiss privacy jurisdiction and Secure file sharing with expiry.
Proton Drive's Achilles heel: storage amounts are small for the price — 200gb for $4/mo when google gives you 100gb for $2/mo. Tresorit's: no free plan and premium pricing — you’re paying a serious tax for the privacy features. 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 スイスグレードの暗号化とeuデータ保管保証が必要な機密データを扱う企業 matters more, Tresorit is your pick. Neither is a bad choice — but one will fit your workflow better.
