Cloud Storage for Business: The 10 Best Solutions in 2026

Someone resigns. Three weeks later you discover the only signed copy of a master services agreement lived in their personal Dropbox, and a public share link from a 2023 project is still open to anyone who has the URL. Storage capacity was never the problem. Control was. That’s what pushes most teams to replace their cloud storage solutions for business, and it’s the axis almost every roundup skips.

So this comparison is organised by who you are rather than by feature count. A Windows shop with Entra ID and a compliance officer needs something different from a video studio moving 200 GB dailies, which needs something different again from a genomics team paying by the terabyte. Ten services below, each one winning a specific buyer. Plus the ones we’d tell you to skip.

Our top picks at a glance

How we evaluated these cloud storage solutions for business

Be clear about what this is. SmartDataCollective has published on data infrastructure and analytics since 2008, and this evaluation draws on documented product capabilities, published pricing models, deployment and residency options, and vendor compliance disclosures. We did not run hands-on trials, benchmark sync speeds or time restores. Where a claim depends on your own environment, we say so instead of pretending a lab result exists.

What we weighted, in rough order:

• Admin depth. Can you see every externally shared file in one view? Can you force link expiry, block downloads by domain, and de-provision a leaver’s access in one action through SCIM?
• Compliance posture. SOC 2 Type II and ISO 27001 are table stakes. The differences show up further out: signed HIPAA BAAs, FedRAMP status, GDPR data residency choices, customer-managed encryption keys, and immutability for regulated retention.
• Recovery, not just storage. Version history depth, retention after deletion, ransomware rollback across a whole team folder. Sync replicates your mistakes at wire speed, which is why a sync tool alone is never a substitute for a real data backup strategy.
• Identity fit. Whatever your IdP is, storage should sit behind it. Anything requiring a separate password list is a liability.
• Cost shape. Per seat, per terabyte, per device, and what egress costs when you leave.
• Data shape. Thousands of small Office files behave nothing like a folder of 40 GB video masters or a CAD assembly with linked references.

Security posture matters more than the marketing copy suggests, and it’s worth reading up on resilience strategies for cloud security issues before you commit a company’s records to any single provider. Vendors increasingly market AI-driven cloud security features such as anomaly detection on downloads; treat those as useful signals, not as a control you can audit.

1. Google Drive — Best overall for collaborative teams

Overview

Drive stopped being a file locker years ago. Inside Google Workspace it’s the storage layer under Docs, Sheets and Gmail attachments, with shared drives holding files at team level so nothing dies with an employee’s account.

What it does well

Real-time co-editing is still the benchmark, and version history reaches back far enough to rescue a document someone flattened on a Friday. Shared drives fix the single biggest ownership problem in small companies: files parked in personal My Drive folders that vanish when the person does. Admin-side, you get SAML SSO, group-based access, context-aware access rules that check device posture before granting a session, DLP scanning that can quarantine files matching a pattern, and Vault for retention and eDiscovery. Search actually works, because Google indexes content rather than filenames alone. Third-party integrations are everywhere, and the API is well documented enough that your ops team can script offboarding audits.

Drawbacks

Governance is tiered. The features you’d want before storing regulated records, including DLP, Vault and client-side encryption, sit on the more expensive Workspace plans, so the sticker price on the entry tier is misleading. Drive for desktop can struggle with very large binary files and with applications that expect a real local filesystem; design and engineering teams often hit this first. Storage is pooled across the org, which is generous until one team’s video archive consumes it. And native Docs formats create export friction if you ever migrate.

Pricing model

Per user, per month, annual or flexible commitment, with pooled storage that increases by tier. Additional storage can be purchased on top.

2. Microsoft OneDrive for Business — Best for Windows and Microsoft 365 shops

Overview

If your identity is in Entra ID and your finance team lives in Excel, OneDrive is less a decision than a default. Underneath, it shares plumbing with SharePoint, which is both its strength and its complexity.

What it does well

Known Folder Move quietly redirects Desktop and Documents into the cloud on managed machines, which solves the “the laptop was stolen with the only copy” problem without asking users to change behaviour. Files On-Demand keeps disks free. Conditional Access lets you block downloads on unmanaged devices while still allowing browser access, an underrated control. Purview brings sensitivity labels that travel with the file, retention policies, and legal hold across mail and files at once, so an eDiscovery request doesn’t turn into a manual scavenger hunt. Co-authoring in desktop Office apps works properly now, including in Excel, which historically was the hard case.

Drawbacks

SharePoint permission inheritance is where good intentions go to die; nested libraries with broken inheritance become unauditable within a year unless someone owns the structure. Sync has documented limits on path length, file counts and certain characters, and teams with deep folder trees inherited from an old file server hit those on day one. The Mac client remains the weaker sibling. Licensing is a maze of E-tiers and add-ons.

Pricing model

Included with most Microsoft 365 business and enterprise seats, or sold standalone per user. Advanced governance features often require a higher tier or a separate Purview licence.

Best for

Windows-managed organisations with an IT function, especially those already paying for Microsoft 365.

3. Dropbox Business — Best for distributed teams and external collaboration

Overview

Dropbox lost the productivity-suite war and responded by getting very good at the thing it started with: moving files between machines reliably.

What it does well

Block-level sync uploads only the changed portion of a file, which is why teams editing large InDesign or video project files keep choosing it over the bundled options. Sharing with outsiders is friction-free for the recipient, and the admin controls around that have matured: link expiry, password protection, view-only defaults, download blocking, and a report of every file shared beyond the team. Rewind restores a whole folder to a point in time, which is the control you want when ransomware encrypts a synced share at 2 a.m. Regional hosting options help with EU data residency requirements, and the platform bundles e-signature and video review tooling that some teams would otherwise buy separately.

Drawbacks

Per-seat cost adds up fast next to storage you’re already paying for in Workspace or Microsoft 365, and paying twice is the most common reason Dropbox gets cut in a renewal review. Team plans carry seat minimums that annoy very small companies. Compliance coverage is solid but not at Box‘s depth for public-sector work. Storage is pooled, and the desktop client has historically been heavier on system resources than rivals.

Pricing model

Per user, per month, billed annually, with seat minimums on team tiers and a limited free personal tier.

Best for

Agencies, studios and remote teams whose daily work involves sending large files to clients who don’t share their stack.

4. Box — Best for enterprise governance and regulated industries

Overview

Box sells content governance and includes storage. That framing explains everything about the product, including the price.

What it does well

Classification drives policy. Label a folder as containing patient data and Box Shield can restrict external sharing, flag anomalous download behaviour, and prevent downloads to unmanaged devices without an admin writing a rule per folder. Retention policies with legal hold survive user deletion. KeySafe lets you hold your own encryption keys in your own KMS and revoke provider access, which is the control that gets a bank’s security review past the finish line. Box holds FedRAMP authorisation for government work, supports HIPAA and FINRA-aligned configurations, and its granular permission model has seven distinct collaborator roles rather than the usual view-or-edit binary. Box Relay handles approval workflows, and Box Sign covers signatures without another vendor.

Drawbacks

It’s expensive once you add governance and key management, and those are the reasons you’d buy it. The desktop sync experience has improved with Box Drive but still lags Dropbox for very large working files. Upload size caps vary by plan. And for a team of twelve with no compliance obligations, most of what you’re paying for sits unused.

Pricing model

Per user, per month with unlimited storage on business tiers; Shield, KeySafe and Governance priced as add-ons. Enterprise deals are negotiated.

Best for

Healthcare, financial services, legal and public sector organisations where an auditor will eventually ask who accessed what.

5. Egnyte — Best for hybrid environments and compliance-heavy mid-market

Overview

Egnyte is the answer to a specific, unglamorous problem: you have a file server that CAD software, a survey instrument or an accounting package still expects to find over SMB, and you also want cloud access for everyone else.

What it does well

Local caching appliances keep hot files on-site at LAN speed while the authoritative copy lives in the cloud, which matters enormously to construction, architecture and engineering firms pushing multi-gigabyte models over patchy site connections. Its governance tooling is aimed at organisations without a large security team: prebuilt policy templates for HIPAA, GDPR, CMMC and financial regulation, content classification that scans for sensitive data patterns across your existing repositories, permission auditing that surfaces the folder someone opened to the whole company in 2021, and ransomware detection that can cut off an infected user account. Life sciences and government contractors are well served here.

Drawbacks

Pricing is quote-based, so comparison shopping takes calls you didn’t want to make. The admin console rewards learning and punishes casual use. For a team that has no on-prem footprint and no regulator, Egnyte is more machinery than the job needs, and Box or Drive will feel lighter. Consumer-grade polish isn’t the priority.

Pricing model

Per user with storage tiers, sold through sales, typically annual, with platform add-ons for governance and threat detection.

Best for

Mid-market firms with legacy file servers, sector-specific compliance obligations and no appetite for a full Microsoft rollout.

6. IDrive — Best for backup-first protection across devices and servers

Overview

Every other service on this list syncs. IDrive backs up, and the difference is not semantic. Sync propagates a deletion; backup keeps the copy you deleted.

What it does well

One account can protect laptops, desktops, external drives, NAS boxes, Windows Server, SQL, Exchange, VMware and Hyper-V, which is why smaller IT teams like it. Backups are incremental at block level after the first pass, versions are retained, and if your initial upload is measured in terabytes the provider will ship you a drive to seed it physically rather than making you saturate the office line for a fortnight. The endpoint management console shows which machines missed their last job, and that report alone justifies the licence in most small companies. IDrive also runs an S3-compatible object storage service for teams that need programmatic access alongside endpoint protection. If you’re weighing options, our guide on why SMBs need the right data backup solution covers the selection questions.

Drawbacks

The interface looks like it was designed by engineers for engineers, and it was. Introductory pricing renews substantially higher, which surprises people in year two. Restores of very large data sets take as long as physics allows unless you pay for a courier drive. It’s not a collaboration platform and doesn’t pretend to be, so most teams run it alongside Drive or OneDrive rather than instead of them.

Pricing model

Annual capacity-based licence covering unlimited devices per account, with separate plans for endpoint fleets, servers and object storage.

Best for

Small and mid-sized businesses that need proof they can restore, not just proof they can share.

7. pCloud — Best for media libraries and large-file workflows

Overview

pCloud mounts as a virtual drive. Your video archive appears in Finder or Explorer, occupies almost no local disk, and streams on demand.

What it does well

For teams sitting on terabytes of footage, photography or audio, that mounted-drive behaviour changes the working day. Built-in media playback means a client can preview a cut without downloading it first. You choose an EU or US data region at signup, which handles the simpler GDPR conversations. The optional client-side encryption folder gives zero-knowledge protection for the subset of files that need it while leaving everything else searchable and previewable, and that split approach is more practical than encrypting everything. The lifetime purchase option is genuinely unusual and appeals to founders tired of subscription creep.

Drawbacks

Admin tooling is basic next to Box or Egnyte. There’s no retention policy engine, no legal hold, no classification. Business plans start at a small seat minimum, and the compliance documentation available is thinner than a regulated buyer will want. A lifetime plan is only as good as the company’s lifetime, which is a real risk calculation rather than a snarky aside. Treat it as fast, pleasant storage rather than a system of record.

Pricing model

Per user, per month or year on business plans; personal tiers also sold as one-off lifetime licences. Client-side encryption is an add-on.

Best for

Production studios, photographers and marketing teams whose files are big and whose compliance obligations are light.

8. Proton Drive — Best for privacy-first and confidentiality-critical teams

Overview

Proton encrypts files, filenames and folder structure on your device. The company operates from Switzerland and publishes its client code, so the privacy claim is at least inspectable.

What it does well

End-to-end encryption is the default rather than a paid folder, which matters for journalists, activists, litigation teams and anyone holding source material they cannot expose to a subpoena served on a provider. Share links can carry passwords and expiry dates while still preserving the encryption model. Business plans include SSO and centralised user management, and Drive comes bundled with encrypted mail, calendar and VPN, so a small firm can buy its whole confidential stack in one contract.

Drawbacks

Zero knowledge cuts both ways. If the provider can’t read your files, it also can’t run server-side DLP, index full text for search, generate previews at scale, or produce content for eDiscovery. Some compliance regimes require exactly those capabilities, so the most private option can be the wrong regulatory answer. Integration coverage is narrow compared with Drive or Dropbox, desktop clients are younger, and collaborative editing is limited. Encryption also isn’t a substitute for the everyday discipline described in these essential cloud security practices, including MFA enforcement and prompt offboarding.

Pricing model

Per user, per month on business plans, usually as part of a bundle with Proton’s other services.

Best for

Legal, research, advocacy and executive teams where confidentiality outranks convenience.

9. Backblaze B2 — Best for data-heavy companies storing bulk data

Overview

When your storage question is measured in hundreds of terabytes, per-seat pricing stops making sense. B2 is S3-compatible object storage priced per terabyte, and it’s the cheapest sane answer for archives, backups and pipeline output.

What it does well

Anything that speaks the S3 API speaks to B2, which covers Veeam, Rclone, Commvault, MSP backup platforms and most homegrown Python jobs. Object Lock provides write-once immutability, so a compromised admin credential can’t delete your last clean backup. Egress is generously handled relative to the hyperscalers, and CDN partnerships remove transfer charges on some routes, which changes the maths for media delivery. Application keys can be scoped to a single bucket with a prefix, so your CI runner never gets keys to the archive. Analytics teams shipping event data offsite should read our piece on off-site backup methods for big data workloads before designing the retention tiers.

Drawbacks

Nobody in marketing is going to open a bucket in a browser and find it pleasant. There’s no sync client worth giving to end users, no sharing UX, no collaboration. IAM is simpler than AWS, which is a virtue until you need per-department policy boundaries. You’ll also pay attention to class B and C transaction charges if your workload is chatty with small objects.

Pricing model

Per terabyte stored per month, metered downloads with a free allowance tied to how much you store, plus API transaction fees. No seats.

Best for

Data engineering, media and research teams whose bill scales with bytes rather than headcount.

10. Apple iCloud+ — Best for Apple-only micro-teams

Overview

Included with every Mac and iPhone, invisible in daily use, and the reason a lot of small creative shops never formally chose storage at all.

What it does well

Desktop and Documents folder sync works without training, photo libraries offload automatically, and iWork collaboration is competent for teams that don’t need Excel. Apple Business Manager issues Managed Apple Accounts, so a company can own the identity rather than relying on a designer’s personal Apple ID holding client work. Shared albums and iCloud Drive folder sharing cover light collaboration. Combined with device management, it’s a defensible setup for a studio of eight Macs.

Drawbacks

This is where we part company with the roundups that rank iCloud highly for Apple businesses. The admin console is device management with storage attached, not content governance: no retention policies, no legal hold, no DLP, no report of every externally shared file, and limited audit visibility into who opened what. Version history is shallow outside iWork documents. Windows access is a compromise. Encryption options differ between Managed Apple Accounts and personal Apple IDs, so confirm the current position before you make an encryption promise to a client. Fine for convenience. Not fine as your only record of company data.

Pricing model

Per account storage tiers, purchasable in volume for Managed Apple Accounts, with entry-level free storage per Apple ID.

Best for

All-Mac teams under roughly a dozen people with no regulatory exposure, ideally paired with a separate backup service.

Tools we considered and left out

Jottacloud. Frequently listed as the unlimited-storage pick, and for a personal photo archive that’s fair. For business we’d pass. Unlimited plans come with fair-use throttling above a threshold, the admin tooling is slim, and support is oriented to a Nordic consumer base. Unlimited that slows down under load isn’t a capacity plan.

Sync.com and Tresorit. Both are credible zero-knowledge platforms, Tresorit especially so for European enterprises needing E2E plus admin policy. They occupy the same slot as Proton Drive here, and listing three near-identical privacy options would pad the list without helping you decide. If Proton’s integration gaps rule it out, look at Tresorit next.

Amazon S3, Azure Blob and Google Cloud Storage. These are excellent and they’re not what this article is about. They’re developer infrastructure, priced with request tiers, storage classes, retrieval fees and egress that will produce a bill your finance team can’t parse. Choose them when engineers are the users. For everyone else, B2 covers the same need with fewer levers.

Wasabi. Attractive per-terabyte rates, but the minimum storage duration policy and egress conditions mean short-lived or high-churn data can cost more than the headline suggests. Model your actual access pattern first.

Nextcloud and ownCloud. Self-hosted, open source, and genuinely good if you have someone who patches servers on a schedule. You’re not buying storage, you’re buying an application to run. Most SMBs who choose this route end up paying for it in unplanned weekends.

MEGA. Generous free tier, real end-to-end encryption, and a corporate history plus transfer quota model that make it a hard recommendation for company records.

ShareFile remains strong for accounting and legal document exchange. It’s narrower than Box or Egnyte, so it fits a workflow rather than a company.

How to choose the right cloud storage solution for your business

Five questions settle most of it.

1. Where does identity live? If you’re on Entra ID, OneDrive removes an integration project. If you’re on Google Workspace, Drive does. Adding a third platform means another SCIM connector to maintain and another place a leaver’s access can linger. Storage should follow identity, not fight it.

2. What will a regulator or a client’s security questionnaire ask for? Write the list before you shortlist vendors. Signed BAA. Data residency in a named region. Customer-managed keys. Immutable retention for a stated period. Audit logs exportable to your SIEM. Half the market drops out immediately, and that’s the point.

3. Is this a collaboration problem or a recovery problem? They’re solved by different products. A synced folder that replicates an encrypted file to every endpoint has done its job perfectly and ruined your week. Most companies need one of each, and it’s cheaper than discovering the gap during an incident. Our list of things to consider when choosing cloud storage goes deeper on that split.

4. What shape is your data? Ten thousand small Word files stress sync clients in a way that a hundred large video files never will, and vice versa. Path depth, filename characters and total object counts break real deployments. Test with a copy of your worst folder, the one everyone avoids, before you migrate.

5. What does leaving cost? Egress charges, proprietary document formats, permission structures that don’t export, and links embedded in three years of email. Companies that have already moved core systems to the cloud tend to price this in; first-timers rarely do. Ask the vendor how bulk export works and how much it costs. The answer tells you how confident they are.

Frequently asked questions

What is the best cloud storage for a business?

For most businesses, Google Drive within Workspace or OneDrive within Microsoft 365, decided by which productivity suite you already pay for. Buying storage separately from your suite means paying twice for capacity and maintaining two permission models. The exceptions are real, though: regulated organisations get more from Box or Egnyte because retention, legal hold and key management are built in rather than bolted on, and data-heavy teams should be looking at object storage priced per terabyte instead of per seat. There is no single winner, only a match between your identity provider, your compliance obligations and the size of your files.

How much does business cloud storage cost?

Four pricing models dominate. Per user per month with pooled storage, which is how Drive, OneDrive, Dropbox and Box sell. Per terabyte per month with metered egress and API calls, used by object storage like Backblaze B2. Annual capacity licences covering unlimited devices, which is how backup services such as IDrive package endpoint protection. And one-off lifetime purchases, offered by pCloud among a few others. The variable that ruins budgets isn’t the headline seat price, it’s the add-ons: DLP, eDiscovery, customer-managed keys and advanced threat detection are usually separate line items or a tier upgrade. Price the configuration you’ll actually deploy, including egress if you ever plan to leave, and get renewal pricing in writing since introductory rates on backup services commonly rise sharply in year two. Understanding how cloud computing benefits your company financially usually means comparing total cost against hardware refresh cycles rather than against last year’s software bill.

Is Google Drive or Dropbox better for business?

Take Drive if you’re on Gmail and Workspace. You already own the storage, shared drives handle ownership properly, and Vault plus DLP give you governance without another vendor. Take Dropbox if your productivity suite is Microsoft or Apple and your daily pain is moving large files to people outside your company. Its sync engine handles big, frequently modified files more gracefully, external recipients don’t need an account to open a link, and Rewind gives you clean folder-level rollback. Where Dropbox loses is redundancy: paying per seat for storage that duplicates what your Microsoft 365 or Workspace licence includes is the first thing a cost review deletes. Where Drive loses is heavy binary workflows and any team that needs the desktop to behave like a real local disk.

What is the most secure cloud storage for business?

Depends which threat you’re defending against. Against a provider being compelled to hand over your files, end-to-end encrypted options like Proton Drive or Tresorit are the strongest answer, because the provider holds no key. Against an insider, a compromised credential or a regulator’s audit, the strongest answers are Box with customer-managed keys and Shield, or Egnyte with its classification and permission auditing, because those give you evidence and policy enforcement that zero-knowledge platforms structurally cannot. Most breaches involving cloud storage don’t come from broken cryptography anyway. They come from a share link set to “anyone with the link”, an account without MFA, or a departed contractor whose access nobody revoked. Enforce SSO with MFA, review external shares monthly, restrict downloads on unmanaged devices, and pipe audit logs somewhere a human reads. That configuration on an ordinary platform beats a perfectly encrypted one run carelessly.
