Cloud storage is a service that keeps a user's files on servers run by a provider and makes them available from any device through desktop sync clients, mobile apps and a web browser. Consumer services sell storage in tiers measured in gigabytes or terabytes, usually as monthly or annual subscriptions, while business versions add user administration, permissions and compliance controls.
This list covers thirteen general-purpose cloud storage services available in 2026, from the platform providers Google, Microsoft and Apple to listed specialists Dropbox and Box, privacy-focused providers such as Proton Drive, Sync.com, MEGA and Tresorit, and smaller companies selling lifetime plans. Prices are shown in US dollars where the vendor's US page displayed them; some vendors served euro pricing to the reviewer and those figures are marked as EUR.
Entries were ranked on verifiable criteria: free allowance, published price per terabyte, encryption model, platform coverage and the disclosed scale and stability of the company. Online backup services and object storage for developers are adjacent categories and are not ranked here.

What is cloud storage
Cloud storage, in the consumer and small-business sense used here, is a hosted file system: a folder on the user's computer or phone is synchronised to the provider's servers, and the same files can be opened, shared or restored from other devices. The provider manages hardware, replication and availability, and charges for capacity.
It overlaps with several neighbouring categories. Cloud backup services copy a whole computer on a schedule for disaster recovery and are not designed for day-to-day file access. File sharing software focuses on sending files to outside parties, often with links and expiry dates. Document management software adds metadata, workflows, retention rules and version control around documents. Developer-oriented object storage (S3-compatible services) stores data accessed by applications through an API rather than through a sync folder; Dropbox and MEGA both launched such products in 2025-2026.
Within cloud storage itself, the main split is between services where the provider holds the encryption keys (Google Drive, OneDrive, Dropbox, Box, standard iCloud) and end-to-end or zero-knowledge services where only the user can decrypt files (Proton Drive, Sync.com, MEGA, Tresorit, Internxt, and iCloud with Advanced Data Protection).
History and market
Consumer file synchronisation became a mainstream product in the late 2000s. Box was started in 2005 and Dropbox was co-founded in 2007. The platform companies followed by building storage into their operating systems and productivity suites: Google's storage is now sold through Google One and Workspace, Microsoft's through Microsoft 365, and Apple's through iCloud+.
The 2010s added a wave of privacy-oriented providers. Sync.com was founded in Toronto in 2011, and Tresorit, now part of Swiss Post, in the same year; MEGA launched in 2013, pCloud in 2013, Proton in 2014 and Internxt in 2020.
The two listed specialists illustrate where the market stands in 2026. Dropbox reported Q3 2026 revenue of US$637.3 million, up 0.5%, with 18.20 million paying users, and announced a move into object storage for AI applications plus the US$350 million purchase of Tigris Data. Box, which sells mainly to enterprises, reported Q2 fiscal 2027 revenue of US$321.1 million, up 9%. Platform bundles have also been repackaged around AI: Google's largest consumer storage tier is now sold as Google AI Pro, and Microsoft moved its Family plan to 2 TB of shared storage in October 2026. No independent market-size figure was verified for this list.
Key features to compare
Free allowance
Free tiers range from 1 GB (Internxt) and 2 GB (Dropbox) to 10 GB (Box, Icedrive) and 15 GB (Google). Google's and Microsoft's free quotas are shared with email, so they fill faster than the headline suggests.
Encryption model
Provider-managed encryption allows server-side search, previews and account recovery. End-to-end encryption means the provider cannot read files, but forgotten passwords may mean lost data and browser features are narrower. Some services make it optional (iCloud's Advanced Data Protection) or a paid add-on (pCloud Encryption).
Price per terabyte
At around 2 TB, published monthly prices cluster around US$9-10 (Dropbox Plus, iCloud+ 2 TB, Icedrive Pro). Microsoft 365 Personal includes 1 TB and the Office apps for US$69.99 a year.
Version history and recovery
Retention of earlier file versions varies from 30 days on Dropbox Plus to a year on Dropbox Advanced and 10 years on Proton Drive Plus.
File size and transfer limits
Box caps single uploads at 250 MB on its free plan and 500 GB on Enterprise Advanced; Dropbox allows transfers of 50-100 GB; MEGA meters monthly transfer quotas.
Sharing and family plans
iCloud+ plans can be shared with five other people, Microsoft 365 Family with up to six, pCloud's family plan with five.
Data location
pCloud lets customers choose Dallas or Luxembourg at sign-up; Swiss, Canadian, Spanish and Gibraltar-based providers appeal to buyers who want to avoid US jurisdiction.
Collaboration
Real-time co-editing is strongest in Google Drive and OneDrive. Encrypted services increasingly add their own editors, such as Proton Docs and Sheets.
Pricing models
Four pricing models are common. Monthly or annual subscriptions by capacity are the norm: Google One from US$0.89 a month for 30 GB, iCloud+ from US$0.99 for 50 GB, Microsoft 365 Basic at US$1.99 for 100 GB. Bundles tie storage to other software, such as Office apps in Microsoft 365, AI features in Google AI Pro or Mail and VPN in Proton Unlimited. Per-user business pricing applies to Dropbox Standard (US$15) and Advanced (US$24), Egnyte (US$22-48) and Box (from US$5). Lifetime plans, a single payment for permanent capacity, are sold by pCloud, Internxt and, seasonally, Icedrive.
Introductory discounts are widespread. Proton's Drive Plus costs US$29.88 for the first year and renews at US$47.88; Sync.com quotes first-year totals; Icedrive offers 30% off the first year. Buyers comparing costs should use renewal prices. Pay-as-you-grow pricing is rarer: MEGA's Pro Flexi charges €15 a month for a 3 TB base and €3.50 for each further terabyte.
How to choose
By device ecosystem. iPhone and Mac households usually start with iCloud+, whose plans are shareable with family; Windows and Office users get the most from Microsoft 365 Personal or Family; Android and Gmail users from Google One.
By privacy requirement. Where the provider must not be able to read files, Proton Drive, Sync.com, MEGA, Tresorit, Icedrive (paid plans) and Internxt encrypt on the device by default; Apple users can switch on Advanced Data Protection.
By budget model. Users who dislike subscriptions can buy pCloud or Internxt lifetime plans, accepting the risk that the vendor may change or fail. Cost-conscious users needing only 100-200 GB will find Google, Microsoft, Apple and Proton tiers under US$3 a month.
By organisation size. Small teams typically use Google Workspace, Microsoft 365 or Dropbox Standard. Regulated enterprises with governance needs look at Box, Egnyte and Tresorit, which add admin controls, retention and compliance tooling.
By region. EU-based buyers can choose pCloud's Luxembourg region, Internxt in Spain or the Swiss providers Proton and Tresorit.
Methodology
Candidates were general-purpose cloud storage services that sell directly to consumers or small businesses, operate under their current brand in November 2026, and publish plan details on their own website. Pure backup services and API-only object storage were excluded. Each entry was checked against the vendor's own pricing, about and support pages, and for listed companies against results filed with the US Securities and Exchange Commission.
The order reflects five weighted criteria: breadth of platform support and integration (25%), published price per terabyte and availability of a useful free tier (25%), encryption model and published security controls (20%), version history, sharing and collaboration features (15%), and disclosed company scale and stability (15%). Where a vendor did not display prices on the page reviewed, the entry says so and no price is stated. No hands-on performance testing was performed and no user ratings are used.
The list
1
Google's file storage, bundled with Gmail and Photos in a 15 GB free quota
Best for: Android users and teams already on Gmail or Google Workspace
Google Drive is the file-storage service of Google, a subsidiary of Alphabet. For consumers, Drive shares one storage pool with Gmail and Google Photos; every Google account receives up to 15 GB free, and additional space is sold through Google One subscriptions. On the US plans page reviewed for this list, Google offered a 30 GB Lite plan at US$0.89 a month, a 100 GB Basic plan at US$1.99 a month and the Google AI Pro bundle with 5 TB at US$19.99 a month, with annual billing advertised as saving up to 16%. The higher tier is now sold primarily as an AI subscription, so buyers who only need storage pay for bundled AI features.
For organisations, Drive is part of Google Workspace, where storage is pooled across the organisation. The Workspace pricing page fetched for this review (served in euros) listed 30 GB per user on Business Starter, 2 TB on Standard and 5 TB on Plus. Drive's main strength is real-time co-editing in Google Docs, Sheets and Slides without file locking, and its integration with Android. Files are not end-to-end encrypted by default, so Google can technically access stored content; privacy-focused buyers usually look at Proton Drive or Sync.com instead.
Key features
- 15 GB free shared with Gmail and Photos
- Real-time co-editing in Docs, Sheets and Slides
- Google One family sharing
- Pooled storage per organisation in Workspace
- Desktop sync client for Windows and macOS
- Gemini AI features on AI Pro tier
Pricing
Free: up to 15 GB. Lite: 30 GB, US$0.89/month. Basic: 100 GB, US$1.99/month. Google AI Pro: 5 TB, US$19.99/month. Annual billing advertised as saving up to 16%.
Google Workspace (page served in EUR): Business Starter €6.80, Standard €13.60, Plus €21.10 per user/month; Enterprise quote-based.
Ownership and history
Drive is operated by Google LLC, part of Alphabet Inc. Consumer storage upgrades are sold under the Google One brand, and business storage under Google Workspace.

2
Microsoft's cloud drive, sold mainly through Microsoft 365 subscriptions
Best for: Windows users and Microsoft 365 households
OneDrive is Microsoft's file-storage service, built into Windows and the Microsoft 365 apps. A Microsoft account without a subscription gets 5 GB of cloud storage, and that quota covers OneDrive files and photos as well as Outlook.com email attachments. Larger quotas come from Microsoft 365 plans rather than standalone OneDrive plans: Microsoft 365 Basic gives 100 GB for US$1.99 a month or US$19.99 a year, and Microsoft 365 Personal gives 1 TB plus the desktop Office apps for US$6.99 a month or US$69.99 a year (shown as reduced from US$99.99).
The household offer changed in late 2026. Microsoft's quota page states that Family and Premium subscriptions started from 8 October 2026 receive 2 TB of shared storage for up to six people, replacing the earlier 1 TB per person, and that the new Pro plan gives 5 TB shared. The same page warns that users who exceed their cloud quota cannot send or receive Outlook.com email. OneDrive's main advantage is value: 1 TB plus Word, Excel and PowerPoint costs about the same as storage alone from many rivals. Its main limitation is that it is tied to the Microsoft account and the Microsoft 365 subscription model.
Key features
- Built into Windows File Explorer
- Files On-Demand placeholders
- Bundled Word, Excel, PowerPoint on Personal and Family
- Shared family storage up to six people
- Outlook.com attachments count toward quota
Pricing
Free: 5 GB. Microsoft 365 Basic: 100 GB, US$1.99/month or US$19.99/year. Microsoft 365 Personal: 1 TB, US$6.99/month or US$69.99/year. Microsoft 365 Family: US$12.99/month or US$129.99/year; new Family subscriptions from 8 October 2026 carry 2 TB shared storage.
Storage quota change in 2026
Family and Premium plans started before 8 October 2026 keep 1 TB per person; new subscriptions from that date, and renewals from 2 May 2027, move to 2 TB shared. Pro moves to 5 TB shared.

Listed sync pioneer with 18.2 million paying users
Best for: Creative teams and cross-platform file sync
Dropbox, Inc. is a Nasdaq-listed company (ticker DBX) headquartered in San Francisco; its about page states that Drew Houston co-founded it in 2007. In its results for the third quarter of 2026, Dropbox reported revenue of US$637.3 million, up 0.5% year on year, total annual recurring revenue of US$2.555 billion and 18.20 million paying users, and described itself as having more than 700 million registered users across about 180 countries.
The consumer offer is narrow at the low end: the free Basic plan holds 2 GB. Plus gives 2 TB for one person with 30 days of version history and 50 GB transfers; Standard and Advanced add team storage (from 3 TB and 15 TB respectively), 180 days or one year of history and 100 GB transfers. Dropbox is known for reliable cross-platform sync and has expanded into adjacent tools such as Dropbox Dash for search, Replay for video review, file transfer and e-signatures. In November 2026 it introduced DBX Agent Cloud, an S3-compatible object storage business, and agreed to acquire Tigris Data for about US$350 million. Files are not end-to-end encrypted by default.
Key features
- 2 GB free Basic plan
- Version history from 30 days to 1 year
- Large file transfers up to 100 GB
- Dropbox Replay video review
- Dropbox Dash content search
- Computer backup and remote wipe
Pricing

Apple's storage subscription, with optional end-to-end encryption
Best for: iPhone, iPad and Mac households
iCloud+ is Apple's paid tier of iCloud, covering iCloud Drive, Photos and device backups. Every Apple account gets 5 GB free; paid US plans are 50 GB for US$0.99 a month, 200 GB for US$2.99, 2 TB for US$9.99, 6 TB for US$29.99 and 12 TB for US$59.99, and all of them can be shared with up to five other family members. Paid plans also include Private Relay, Hide My Email, custom email domains and HomeKit Secure Video camera support (one camera on 50 GB, five on 200 GB, unlimited from 2 TB).
Security is configurable. Under the default standard data protection, 15 data categories such as Keychain and Health are end-to-end encrypted, but iCloud Drive and Photos are encrypted with keys Apple holds. Turning on Advanced Data Protection extends end-to-end encryption to 25 categories, including iCloud Drive, Photos and iCloud Backup, and requires iOS 16.2, iPadOS 16.2 or macOS 13.1 or later. iCloud is the natural choice inside Apple's ecosystem, but its Windows client is less complete and there is no Android app for iCloud Drive.
Key features
- 5 GB free with every Apple account
- Family Sharing with up to five others
- Advanced Data Protection (opt-in end-to-end encryption)
- Private Relay and Hide My Email
- HomeKit Secure Video storage
- Tiers from 50 GB up to 12 TB

Swiss-registered storage provider known for one-off lifetime plans
Best for: Individuals who prefer a one-time payment over a subscription
pCloud is operated by pCloud International AG, a company registered in Switzerland with its registered office in Baar. Its about page gives 2013 as the founding year and cites a user base of more than 22 million (elsewhere on the same page, over 24 million). Customers choose at sign-up between a US data region in Dallas, Texas and an EU region in Luxembourg.
pCloud is distinctive for selling lifetime plans as one-off purchases alongside annual subscriptions. The pricing page reviewed, which was served in euros during a Black Friday promotion, listed lifetime list prices of €279 for Premium (500 GB), €709 for Premium Plus (2 TB) and €2,799 for Ultra (10 TB), with sale prices of €159, €379 and €1,099 respectively; a 3-in-1 bundle with 3 TB, pCloud Encryption and the pCloud Pass password manager listed at €1,517 (sale €579). A family plan for up to five users is also offered. Client-side encryption (pCloud Encryption) is an extra rather than a default, which means standard folders are not zero-knowledge. A lifetime plan is a bet on the company's long-term survival, which buyers should weigh against the saving.
Key features
- Lifetime one-off purchase plans
- US (Dallas) or EU (Luxembourg) data region
- pCloud Encryption client-side add-on
- Family plan for up to five users
- pCloud Pass password manager in bundle
Pricing
Prices as shown in EUR during a promotion: Premium 500 GB lifetime €279 (sale €159); Premium Plus 2 TB €709 (sale €379); Ultra 10 TB €2,799 (sale €1,099); 3in1 Bundle 3 TB with Encryption and Pass €1,517 (sale €579).

End-to-end encrypted storage from the Swiss maker of Proton Mail
Best for: Privacy-focused users who also want encrypted email and VPN
Proton Drive is made by Proton AG, a Swiss company founded in 2014 and based in Geneva (Plan-les-Ouates), whose primary shareholder is the non-profit Proton Foundation. Files are encrypted on the user's device before upload, so only the account holder holds the keys; Proton states its code is publicly available and that the service is regularly audited by independent experts. Apps exist for Windows, macOS, Android, iOS and the web, with a CLI, and the suite includes Proton Docs and Proton Sheets for encrypted editing.
Pricing in US dollars on 12-month billing starts with a free 5 GB plan, then Drive Plus with 200 GB for US$2.49 a month (US$29.88 for the first year, renewing at US$47.88), Proton Unlimited with 500 GB plus Mail, VPN and Pass for US$6.49, Proton Duo with 2 TB for US$14.99 and Proton Family with 3 TB for US$23.99; Drive Professional for businesses gives 1 TB per user at US$7.99. Drive Plus includes 10 years of version recovery. The trade-off is that introductory prices rise at renewal and the largest personal tier, 3 TB on the family plan, is small next to Google or pCloud.
Key features
- Client-side end-to-end encryption
- Open-source apps
- 10-year version history on Drive Plus
- Proton Docs and Sheets editors
- Apps for Windows, macOS, Android, iOS, web and CLI
Pricing
12-month billing, USD: Free: 5 GB. Drive Plus: 200 GB, US$2.49/month (US$29.88 first year, renews US$47.88). Proton Unlimited: 500 GB + other Proton apps, US$6.49/month. Proton Duo: 2 TB, US$14.99/month. Proton Family: 3 TB, US$23.99/month. Drive Professional: 1 TB/user, US$7.99/user/month.

Toronto-based end-to-end encrypted storage with HIPAA option
Best for: Small businesses and professionals needing encrypted sharing
Sync.com is a Canadian provider founded in 2011 by Thomas Savundra, Suhan Shan and Darius Antia, operated by Sync.com Inc. from Toronto, Ontario; it says more than 2 million individuals and businesses use its products. Its storage is end-to-end encrypted, so that, in the company's words, only the user has access to their files, and it lists SOC 2 Type 1 compliance.
The individual plans are billed annually: Personal 1TB at US$9 a month (US$108 for the first year), Solo 5TB at US$21 a month (US$252) and Personal Unlimited at US$33.75 a month (US$405), each with a 30-day free trial; HIPAA compliance is listed only on the Solo 5TB plan. Sync competes with Proton Drive on privacy but focuses more on file sharing and team workflows than on an email-and-VPN bundle. Because data is encrypted client-side, in-browser previews and collaborative editing are more limited than in Google Drive or OneDrive, and annual billing is required on the plans shown.
Key features
- End-to-end encrypted storage and sharing
- SOC 2 Type 1 compliance
- HIPAA compliance on Solo 5TB
- Unlimited-storage personal tier
- 30-day free trial
Pricing
Billed annually: Personal 1TB: US$9/month (US$108 first year). Solo 5TB: US$21/month (US$252). Personal Unlimited: US$33.75/month (US$405). 30-day free trial.

NYSE-listed enterprise content platform used by 68% of the Fortune 500
Best for: Regulated enterprises needing governance and integrations
Box, Inc. (NYSE: BOX), headquartered in Redwood City, California, was started in 2005 and states that 97,000 companies and 68% of the Fortune 500 are customers. It now describes itself as an Intelligent Content Management platform. For the second quarter of fiscal 2027 (to 31 July 2026) Box reported record revenue of US$321.1 million, up 9%, and remaining performance obligations of US$1.7 billion, attributing growth to its Enterprise Advanced plan.
Box is less a consumer drive than a governed content layer. A free Individual plan gives 10 GB with a 250 MB upload limit, and Personal Pro gives 100 GB with a 5 GB limit. Business plans require at least three users and offer unlimited storage, with single-file upload limits rising from 5 GB on Business to 15 GB on Business Plus, 50 GB on Enterprise, 150 GB on Enterprise Plus and 500 GB on Enterprise Advanced. The pricing page advertises plans from US$5 per user per month but did not display per-plan prices when reviewed. Upload caps on lower tiers and the three-user minimum make Box a poor fit for individuals.
Key features
- Unlimited storage on business plans
- Single-file uploads up to 500 GB (Enterprise Advanced)
- AI agents over stored content
- Admin governance and retention controls
- Free 10 GB Individual plan
Pricing
Individual: free, 10 GB, 250 MB upload limit. Personal Pro: 100 GB, 5 GB upload limit. Business Starter, Business, Business Plus, Enterprise, Enterprise Plus, Enterprise Advanced: 3-user minimum; headline price 'from US$5 per user/month'; Enterprise Plus and Advanced annual billing only. Per-plan prices were not displayed on the page reviewed.

Zero-knowledge storage platform launched in 2013, billed in euros
Best for: Users who want encrypted storage with large transfer quotas
MEGA was released in 2013 after, by the company's account, three months of coding by Mathias Ortmann and Bram van der Kolk; it says one million users registered in the first three days and that it passed 200 million registered users in October 2020. Its about page lists the head office in Csomád, Hungary, with further offices in Auckland, New Zealand and Salamanca, Spain, and reports fewer than 45 million monthly active users in Europe under the EU Digital Services Act.
MEGA applies zero-knowledge encryption, meaning data is encrypted and only the user holds the keys. Its consumer range runs from a free plan through Pro Lite, Pro I and Pro III, with a Business tier for three or more users; paid plans bundle MEGA VPN and the MEGA Pass password manager. All transactions are charged in euros. For heavy users, Pro Flexi has a base of 3 TB storage and 3 TB transfer for €15 a month, with €3.50 per additional terabyte of storage or transfer, whichever is greater. Recent additions include Transfer.it, the S3-compatible MEGA S4 object storage and support for AI agents through MEGA CMD. A drawback is the transfer quota: downloads and shares count against a monthly allowance, which free users notice quickly.
Key features
- Zero-knowledge end-to-end encryption
- Bundled MEGA VPN and MEGA Pass
- Pro Flexi pay-per-TB scaling
- Transfer.it file transfer service
- MEGA S4 S3-compatible object storage

Gibraltar-based storage with 10 GB free and Twofish client-side encryption
Best for: Budget buyers wanting a large free tier
Icedrive is operated by Ice Privacy Ltd, whose site footer gives an address at the World Trade Center in Gibraltar. It offers 10 GB of free storage, one of the larger free allowances in this list. Paid plans include 100 GB, Pro 2 TB, 5 TB and 10 TB tiers; on the page reviewed only the 2 TB Pro tier showed a price, at US$8.99 a month normally, discounted to US$6.29 a month or US$75.52 for the first year under a new-customer offer. The company's FAQ says it supports GBP, USD and EUR as standard currencies.
Encryption is the distinguishing technical choice. Icedrive uses client-side encryption with the Twofish algorithm rather than AES, and states that file and folder names are encrypted on the device and that keys never reach its servers; the free plan is listed without encryption, which is reserved for paid plans. Lifetime plans are promoted seasonally but were not priced on the page reviewed. The company publishes little about its founding, ownership or user numbers, so long-term commitments carry more uncertainty than with listed providers.
Key features
- 10 GB free plan
- Client-side Twofish encryption on paid plans
- Encrypted file and folder names
- Plans from 100 GB to 10 TB
- Seasonal lifetime plans
Pricing
Free: 10 GB, no client-side encryption. Pro 2 TB: US$8.99/month standard; new-customer offer US$6.29/month or US$75.52 for the first year. 100 GB, 5 TB and 10 TB tiers exist; prices not shown on the page reviewed.

Encrypted file storage owned by Swiss Post
Best for: Businesses needing end-to-end encrypted collaboration
Tresorit was founded in 2011 and is now part of Swiss Post, sitting within the postal operator's digital business services; it has offices in Switzerland, Germany and Hungary and says about 11,000 organisations use its product. It is positioned as an end-to-end encrypted alternative to mainstream business drives, aimed at legal, healthcare and other confidentiality-sensitive teams.
Personal plans are Personal Lite (50 GB, 2 GB maximum file size), Personal Essential (1 TB, 10 GB maximum file size) and Personal Pro (4 TB, 10 GB maximum file size), with monthly and yearly billing; any plan can be tried for 14 days without limitations, and there is no permanent free tier listed. Business plans start at three users with 2 TB of encrypted storage per user. The pricing page renders prices with JavaScript in the visitor's local currency and did not display figures when reviewed, so prices are not reproduced here. Compared with Proton Drive and Sync.com, Tresorit is more expensive at the low end and its 2 GB file limit on the entry plan is restrictive, but Swiss Post ownership and a business-first design make it a common shortlist choice for regulated organisations.
Key features
- End-to-end encryption by default
- 14-day free trial on any plan
- Personal plans from 50 GB to 4 TB
- Business plans with 2 TB per user
- Offices in Switzerland, Germany and Hungary

Open-source, zero-knowledge storage from Valencia, Spain
Best for: Users who want open-source, EU-based encrypted storage
Internxt was founded in 2020 by Fran Villalba Segarra and is based in Valencia, Spain; it says it serves more than one million active users. The operating entity named on its site is Internxt Universal Technologies SL. The company describes its software as fully open source and states that its code was verified by the penetration-testing firm Securitum; it also displays a certification badge for Spain's National Security Scheme (ENS) at high category.
Internxt offers 1 GB free and three paid tiers: Essential (1 TB), Premium (2 TB) and Ultimate (5 TB), each sold on annual or lifetime terms. Files are protected with zero-knowledge AES-256 encryption, which the company describes as post-quantum. When the pricing page was reviewed, the lifetime prices displayed as a €0 placeholder and annual prices were not shown, so prices cannot be stated here. The 1 GB free tier is the smallest in this list, and as a young company Internxt has a shorter track record than pCloud or Proton.

Governed file platform for mid-market firms, backed by GI Partners and TA
Best for: Mid-sized firms in construction, life sciences and professional services
Egnyte has offered cloud file sharing to businesses since 2008 and is a portfolio company of the private-equity firms GI Partners and TA Associates; it cites more than 23,000 customers. Rather than competing on consumer storage, it sells a governed content platform combining file sharing, permissions, data-governance and compliance tools, often used alongside on-premises file servers in hybrid deployments.
Published prices are per user per month, paid annually: Business at US$22 (up to 100 users), Enterprise Lite at US$39 and Elite at US$48, with Ultimate quoted on request; the pricing table lists 100 GB on Business and 150 GB on the higher tiers in its file-upload row, and multi-year discounts are available. A free trial is offered, though its length is not stated. Egnyte has no free tier and no single-user plan, which places it outside consumer comparisons, and its per-user cost is several times that of Google Workspace or Dropbox Standard. It is included here because many businesses searching for cloud storage need governance rather than raw capacity.
Key features
- Hybrid cloud and on-premises file access
- Permissions and data governance tools
- Large file uploads up to 150 GB
- Business plan up to 100 users
- Multi-year discounts
Pricing
Paid annually, per user/month: Business: US$22 (max 100 users). Enterprise Lite: US$39. Elite: US$48. Ultimate: quote-based. Free trial available.

Frequently asked questions
What is the best cloud storage overall?
No single service suits every user. Google Drive offers the largest free allowance at 15 GB and cheap upgrades from US$0.89 a month, Microsoft 365 Personal bundles 1 TB with Office for US$69.99 a year, and iCloud+ is the default for Apple users. Buyers who need end-to-end encryption by default usually choose Proton Drive or Sync.com instead.
Which cloud storage gives the most free space?
Among the services listed, Google gives up to 15 GB free, shared with Gmail and Photos, while Box and Icedrive each give 10 GB. Proton Drive and Apple iCloud give 5 GB, as does a Microsoft account without a subscription. Dropbox Basic gives 2 GB and Internxt 1 GB.
Is cloud storage safe for private files?
All major services encrypt data in transit and at rest, but in most mainstream services the provider holds the keys. End-to-end encrypted services such as Proton Drive, Sync.com, MEGA and Tresorit encrypt files on the device so the provider cannot read them. Apple users can enable Advanced Data Protection to extend end-to-end encryption to iCloud Drive and Photos.
How much does 2 TB of cloud storage cost?
Published prices for about 2 TB cluster near US$9-10 a month: Dropbox Plus is US$9.99, iCloud+ 2 TB is US$9.99 and Icedrive Pro 2 TB is US$8.99 before discounts. Proton Duo, which bundles 2 TB with other Proton apps, is US$14.99 a month on annual billing. pCloud sells 2 TB as a one-off lifetime purchase.
Are lifetime cloud storage plans worth it?
Lifetime plans, sold by pCloud, Internxt and occasionally Icedrive, replace subscriptions with one payment. They can be cheaper over several years, but the plan lasts only as long as the company does and terms can change. pCloud's 2 TB lifetime plan had a €709 list price on the page reviewed.
What is the difference between cloud storage and cloud backup?
Cloud storage synchronises chosen folders across devices so files can be opened and shared anywhere; deleting a file usually deletes it everywhere after the retention window. Cloud backup copies a whole computer or server on a schedule, keeps historical snapshots and is designed for recovery after loss or ransomware rather than daily access. Many users combine one of each.
Which cloud storage is best for business?
Small teams typically use the storage built into Google Workspace or Microsoft 365, or Dropbox Standard at US$15 per user a month. Larger and regulated organisations use Box, whose business plans start at three users with unlimited storage, Egnyte from US$22 per user a month, or Tresorit for end-to-end encrypted collaboration.
