Dropbox vs Google Drive——どっちが優秀？
Dropboxを選ぶべき人: 信頼できるファイル同期・共有・大容量ファイル転送が必要なフリーランサーや小規模チーム

本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
Dropbox stands out with Smart Sync for disk space management and Paper for collaborative docs. Google Drive counters with Deep Google Workspace integration and Real-time collaboration on Docs/Sheets/Slides.
Dropbox's Achilles heel: only 2 gb free is laughable in 2026 — google gives 15 gb and most competitors give 5–10 gb. Google Drive's: 15 gb shared across gmail, drive, and photos fills up fast — you’ll be paying within months of heavy use. Pick whichever weakness you can live with.
結論
If you value smart sync for disk space management and 信頼できるファイル同期・共有・大容量ファイル転送が必要なフリーランサーや小規模チーム, go with Dropbox. If 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 matters more, Google Drive is your pick. Neither is a bad choice — but one will fit your workflow better.
