  • Number of devices: Unlimited
  • Encryption: In transit and at rest


  • Fast file uploads and downloads
  • Backed by the power of the Microsoft ecosystem
  • Very user-friendly web interface


  • Average security tools

Post-Windows 10, OneDrive has been the main Microsoft cloud storage solution, as it's integrated into the file explorer for immediate access. Via Android and iOS apps, as well as a macOS app, OneDrive for Business is interlinked with Microsoft 365, to boost productivity with its many collaborative features.

The best of these include selective syncing, multi-page scanning, access anywhere from any device, 1TB per person on the cheapest plan, and the aforementioned interaction with Microsoft Office apps via 365.

What is cloud storage for business?

Cloud storage works by storing data on a physical drive, before making the data accessible via an online software platform to users whenever and wherever they want to view it.

Many business cloud storage providers rank among the best apps to share files as a result, and fall into one of two camps: self-hosted, utilizing on-premises (on-prem) infrastructure; or storage as a service (StaaS), using externally managed, third-party infrastructure. A combination is known as hybrid cloud storage.

StaaS providers achieve economies of scale by managing advanced, expansive data centers, and thus can provide large, affordable levels of storage. In comparison to self-hosted services, StaaS providers are always more affordable per TB, and are known as storage and syncing platforms because they're designed for collaboration.

They provide the ability to seamlessly upload and access data, as well as edit or share it, from any connected device. Cloud sync technology meanwhile encompasses link sharing and file versioning, allowing for simple sharing of documents within and across businesses.

Users can track document changes and incorporate colleague edits, allowing StaaS products to provide a cohesive and integrated digital environment.

How to choose the best cloud storage for business

When looking for the best cloud storage for business, you must ensure that the provider you choose offers stable, highly secure storage, and is able to protect company data - often both sensitive and important - at all times.

Look for services offering end-to-end encryption and zero-knowledge architecture. Both security elements are integral, with the former meaning providers are almost hack-proof, but the latter is particularly significant, because your cloud storage service is unable to access your data, even if law enforcement authorities compel them to.

Many services offer in-transit and at-rest encryption, so data is totally indecipherable even if a cybercriminal intercepted it. Both your data and the infrastructure housing it are protected, with StaaS organizations housing servers in highly secure data centers with 24/7 security, biometric authorization for entry, and frequent security auditing.

These safeguards are particularly crucial for enterprise and business cloud storage, especially if you're operating in privacy or data-sensitive industries. It's non-negotiable at this level to invest in cloud storage providing the very best security, especially if you're planning on going cloud-native.

Data center locations are key too, as different countries have different privacy laws, so you'll need to ensure data is stored in a country that complies with the data privacy obligations of your business. This is where the best web hosting services cross over with cloud, specifically the best cloud hosting providers, because regional cloud hosting is affected in the same way.

As well as security, administrator controls for businesses using StaaS providers (which covers most business cloud storage services) enable managers and IT staff to oversee access and system usage. Elements such as 2FA, roles-based permissions, access management, and auditing are just some of the controls available, and StaaS providers also utilize cloud sync technology to offer collaborative functionality as well as seamless digital workflows.
