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 Powerful search across files and Shared drives for teams. OneDrive counters with Personal Vault for sensitive files and Ransomware detection and recovery.
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. OneDrive's: sync client can be flaky — conflict files and mysterious sync failures still plague power users. Pick whichever weakness you can live with.
結論
If you value powerful search across files 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 word・excel・outlookとシームレスに動くクラウドストレージが欲しいmicrosoft 365ユーザー matters more, OneDrive is your pick. Neither is a bad choice — but one will fit your workflow better.
