How to choose
If your team exceeds 5 GB per user, avoid OneDrive's standalone free tier (5 GB) and Dropbox's free tier (2 GB); consider Google Drive's 15 GB free tier or paid plans starting at $1.99/month for 100 GB.
Choose Box if you require specific certifications like HIPAA or FedRAMP; note that Box requires a three-user minimum and annual billing for listed prices starting at $5/user/month.
For seamless Word/PowerPoint integration without app-switching, OneDrive is superior as it is included with Microsoft 365 Business Basic ($5.40/user/month).
Select Peony if you need branded sharing rooms and page-level analytics; note that its Business plan costs $30/admin/month, which is higher than per-user models.
Our verdict
Microsoft OneDrive is the top pick for most Microsoft 365 users due to its native integration and inclusion in Business Basic plans at $5.40/user/month, while Box is the best alternative for regulated industries needing HIPAA/FedRAMP compliance.
