SharePoint, Google Drive or Dropbox: comparing cloud file storage

Start with what you already pay for

If your business runs on Microsoft 365, you already have SharePoint and OneDrive included in most business plans, along with Teams, which stores its files in SharePoint behind the scenes. If you use Google Workspace, Google Drive and shared drives are part of the package. Paying for a separate file service on top is sometimes justified, but it should be a deliberate choice rather than a habit carried over from before you had either suite. Running two file platforms side by side is where confusion starts. Staff are unsure where the latest version lives, files are duplicated, and permissions have to be managed twice. Choosing one main home for company documents is usually more important than which home you choose.

SharePoint and OneDrive

OneDrive is for each person's own working files, and SharePoint holds shared team and company libraries. Their strength is depth: fine-grained permissions, version history, retention and sensitivity labelling in higher plans, and tight links with desktop Word, Excel and Outlook, including several people editing the same document at once. Large organisations use it to run intranets and records management, and those features are available to small businesses too.

The weakness is complexity. Without a planned structure, SharePoint becomes a maze of Teams-created sites with inconsistent permissions. Sync problems can appear when people sync too many libraries or very large folders. A small amount of upfront design, deciding on a few sites with clear owners, avoids most of the pain.

Google Drive

Google Drive works naturally with Docs, Sheets and Slides, which were designed for browser-based, real-time collaboration and remain excellent at it. Shared drives give teams a common space owned by the organisation rather than by individuals, so files are not lost when someone leaves. Search is fast and good at finding content inside documents, and the interface is easy for new staff to pick up.

Offices that depend on desktop Microsoft Office files, complex Excel models or Word templates sometimes find working between formats frustrating. Drive for desktop handles sync, and the admin console offers sharing controls, data protection and retention options depending on the Workspace edition. Make sure files live in shared drives rather than personal My Drive folders.

Dropbox

Dropbox began as a file sync service and remains very good at it, with reliable syncing, simple sharing links and a clean interface that external clients and contractors tend to find easy. It works across Windows, Mac and mobile without favouring one office suite, which suits creative teams, mixed Mac and PC offices and businesses that exchange large files with outsiders.

Business plans add team folders, admin controls, version history and extra security features, depending on the tier. The trade-off for a business already on Microsoft 365 or Google Workspace is an additional cost, another set of accounts to manage and another place to look for files, unless single sign-on and clear rules are in place.

Things to compare whatever you choose

Look at how sharing with outsiders is controlled: can you require links to expire, block downloads or limit sharing to certain domains? Check how permissions are inherited and how easy it is to see who has access to a folder. Compare version history, how long deleted files are recoverable, and whether there is a separate backup option, because sync is not a backup. Consider the practical side too: storage included per user or per organisation, file size limits, how well large folders sync on your devices, and where data is stored. Check current plans and limits with each vendor, because they change.

Think about the people side as well. Ask a few staff from different roles to try the day-to-day tasks on the platform you are leaning towards: saving from the desktop apps, sharing with a client, finding an old file and working offline on a laptop. Their reactions reveal friction that feature lists hide, and they will be more willing to adopt a system they helped test. If you are moving from one platform to another, plan the migration so files keep their folder structure, version history where possible and sensible permissions, rather than dumping everything into one big shared folder.

Making the call

For most offices the answer is the file service that comes with the email and office suite already in use, set up properly. Consider a different platform only for a clear reason: heavy external collaboration, a creative workflow the main suite handles poorly, or a client requirement. Whichever you pick, design the folder structure, set permissions by team, train staff and add an independent backup. Office IT can review an existing setup as part of a health check, but the decisions themselves are straightforward once the business agrees on one home for its files.
