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. Sync.com counters with End-to-end encryption by default and Zero-knowledge privacy.
Dropbox's Achilles heel: only 2 gb free is laughable in 2026 — google gives 15 gb and most competitors give 5–10 gb. Sync.com's: no native document editing — you have to download files, edit locally, and re-sync every time. 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 追加料金なしでデフォルトのzero-knowledge encryptionが欲しいプライバシー第一のチーム matters more, Sync.com is your pick. Neither is a bad choice — but one will fit your workflow better.
