Google Drive vs Proton Drive——どっちが優秀？
Google Driveを選ぶべき人: Googleエコシステムにいて、Docs・Sheets・Gmailとシームレスに連携するファイルストレージが欲しい人
Proton Driveを選ぶべき人: 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
私たちの見解: Google Drive for simplicity, Proton Drive for power users.

本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
Google Drive stands out with Deep Google Workspace integration and Real-time collaboration on Docs/Sheets/Slides. Proton Drive counters with End-to-end encrypted file storage and sharing and Zero-access encryption — even Proton cannot read your files.
Google Drive's Achilles heel: 15 gb shared across gmail, drive, and photos fills up fast — you’ll be paying within months of heavy use. 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.
結論
If you value deep google workspace integration and googleエコシステムにいて、docs・sheets・gmailとシームレスに連携するファイルストレージが欲しい人, go with Google Drive. If 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 matters more, Proton Drive is your pick. Neither is a bad choice — but one will fit your workflow better.
