イチオシ
1

Google Drive

Free 15GB / $7/user/mo 30GB

The default file sharing layer for remote-first companies

おすすめの理由

Real-time co-editing in Docs, Sheets, and Slides makes Google Drive the operating system of remote work

注意点

15GB free per user fills fast and Google Docs formatting breaks in Word-centric industries

2

Dropbox Business

$15/user/mo

Reliable sync with Dropbox Paper for team documentation

おすすめの理由

Smart Sync keeps files accessible without eating local storage — ideal for remote workers on laptops with limited SSDs

注意点

Expensive per-user and Dropbox Paper is inferior to Notion/Google Docs

3

OneDrive

$6/user/mo 1TB

Seamless for remote teams already running Microsoft 365

おすすめの理由

Deep SharePoint integration and real-time co-authoring in Word/Excel/PowerPoint serve enterprise-adjacent remote teams

注意点

Sync client has a history of conflicts and the UI is less intuitive than Google Drive

4

Box

$15/user/mo

Enterprise-grade cloud storage with granular security controls

おすすめの理由

Watermarking, classification labels, and detailed audit logs serve regulated remote teams in healthcare, finance, and legal

注意点

No built-in document editing — you need separate Office or Google licenses

5

Nextcloud

Free (self-hosted) / $4/user/mo managed

Self-hosted cloud storage for teams that won't trust third parties with their data

おすすめの理由

Full control over data location and zero vendor lock-in — remote teams with compliance requirements love it

注意点

Self-hosting requires DevOps knowledge and ongoing maintenance

評価基準

  • Docs、Sheets、Slidesがライブカーソル、コメント、提案モードによる同時編集をサポート。非同期コラボレーションの極致
  • ファイルはMac、Windows、Linux、iOS、Androidで即座に同期。デバイス間の互換性問題なし
  • 共有設定は「リンクを知っている全員」からドメイン制限付きアクセスまで、ファイルごとに閲覧/コメント/編集の粒度で設定可能

おすすめしないもの

iCloud DriveApple ecosystem only — useless for remote teams on mixed OS
MegaGenerous free storage but no team management, permissions, or collaboration features
