Business cloud storage and sharing

There isn’t one universal “best,” but for most businesses I’d narrow it to Microsoft SharePoint/OneDrive, Google Drive, Dropbox, and Box.

My practical recommendation

If your company already pays for Microsoft 365, use SharePoint + OneDrive. It avoids buying another platform and gives you sophisticated control over internal and external sharing. Microsoft supports organization/site-level sharing controls, guest access, domain restrictions, expiration, and authenticated external sharing.Microsoft Learn+1

If you're primarily a Google Workspace company, Google Drive is the natural choice.

If your main requirement is simply “make it extremely easy for employees and clients to exchange large numbers of files,” Dropbox Business is worth considering. Dropbox provides granular file/folder permissions, password-protected links, expiration dates, and encryption at rest and in transit.Dropbox+1

One important distinction: file storage/collaboration and secure client file exchange aren't always the same problem. If you're sharing sensitive documents with customers, vendors, or outside counsel, I'd evaluate authentication, link expiration, download controls, audit logs, retention, and compliance—not just storage capacity.

If you tell me (1) company size, (2) Microsoft 365 vs Google Workspace, (3) approximate storage needed, and (4) whether you're sharing files with clients externally, I can give you a much more specific comparison, including current pricing.

For most teams, I’d narrow it to Google Drive, Microsoft OneDrive/SharePoint, Dropbox, and Box. The right choice depends heavily on the apps your team already uses.

My practical recommendation

• Already using Google Workspace → Google Drive
• Already using Microsoft 365 → OneDrive + SharePoint
• Want the simplest dedicated file-sharing experience → Dropbox
• Need sophisticated enterprise security/content management → Box

One important distinction: OneDrive isn't really the Microsoft equivalent of a shared team drive by itself. Microsoft recommends using SharePoint team sites for files that several people regularly collaborate on, while OneDrive is primarily for an individual's work files.Microsoft Learn

If you tell me team size, approximate storage needed, whether you use Google or Microsoft 365, and your budget, I can give you a much more specific comparison of the plans and costs.
