Dropbox vs iCloud——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
iCloudを選ぶべき人: Apple全投入なら考えずに使えるバックアップとSyncが欲しいAppleユーザー
私たちの見解: Dropbox for simplicity, iCloud for power users.

|---|---|---|

| 学習コスト | 簡単 | 簡単 |
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. iCloud counters with Seamless sync across iPhone, iPad, and Mac and iCloud Drive with Finder and Files app integration.
Dropbox's Achilles heel: only 2 gb free is laughable in 2026 — google gives 15 gb and most competitors give 5–10 gb. iCloud's: terrible experience on windows and android — and 5gb free in 2026 is embarrassingly stingy. 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 apple全投入なら考えずに使えるバックアップとsyncが欲しいappleユーザー matters more, iCloud is your pick. Neither is a bad choice — but one will fit your workflow better.
