Proton Drive review

Proton Drive is cloud storage for files and photos, with end-to-end encryption. Proton says its encryption is designed to prevent access to your data without your permission. The service also supports secure file sharing and access across devices, according to Proton’s homepage.

It is part of Proton’s wider service lineup, rather than a separately priced Drive product in the published pricing information. That distinction matters when comparing costs: the listed plans bundle Drive storage with other Proton services. The Free plan includes up to 5 GB of Drive storage, while paid plans listed in the comparison include 15 GB or 500 GB. All three include end-to-end encrypted Drive, one user, and Proton’s online document editor and spreadsheets.

The short version: Proton Drive is aimed at people who prioritize encrypted storage and file sharing. Whether it works as a full-time replacement for a mainstream everyday drive depends on how much you need from its apps.

Encryption is the clearest reason to consider Proton Drive. Proton says files and photos are stored with end-to-end encryption, and its homepage presents the service as a way to store and share securely. Cross-device access is also part of the offer, according to Proton. For someone who wants encrypted storage within Proton’s services, those are concrete benefits—not just a promise of extra capacity.

The free plan gives basic personal users up to 5 GB, according to the comparison table. Paid options raise that cap while retaining the same listed core Drive features:

• Free: $0 per month, up to 5 GB, one user.
• Mail Plus: $4.99 monthly, or $3.99 per month billed annually ($47.88 per year), with 15 GB and one user.
• Unlimited: $12.99 monthly, or $9.99 per month billed annually ($119.88 per year), with 500 GB and one user.

Each listed plan includes end-to-end encrypted Drive and Proton’s online document editor and spreadsheets. The pricing page does not list a standalone Drive plan, so compare these prices as bundles, not as storage-only rates. The listed tiers make it possible to start free and pay for more storage and Proton services when needed.

Proton’s pricing information does not show a Drive-only subscription. That makes a direct storage-price comparison harder: Mail Plus and Unlimited bundle Drive with Proton services, and the listed prices are not the cost of storage alone. Capacity is also a concrete constraint. Free includes up to 5 GB, Mail Plus includes 15 GB, and Unlimited includes 500 GB, according to the comparison table. The pricing page lists no higher-capacity Drive tier in the published information.

Everyday usability is the bigger concern in user discussions. In one 2026 Reddit thread, users said the mobile app lacked file search; a commenter said the desktop program handled active files and syncing better, while the mobile and web apps were less useful. Those are user reports, not a product specification, but they point to a gap between encrypted storage and a polished daily-work drive. Another Reddit thread about an unofficial Linux client reflects frustration among Linux users waiting for an official client. If you rely on mobile search or Linux access, check current app support before switching.

Proton does not list a standalone Drive price in the published pricing details. Its storage comes in bundles: Free includes up to 5 GB, Mail Plus includes 15 GB, and Unlimited includes 500 GB. Each plan covers one user and includes end-to-end encrypted Drive.

Mail Plus is listed at $4.99 per month, or $3.99 per month when billed annually ($47.88 for the year). Unlimited is $12.99 monthly, or $9.99 per month billed annually ($119.88 yearly). That’s a jump from 15 GB to 500 GB, but you’re paying for a wider Proton bundle, not just extra Drive storage. The free tier includes an online document editor and spreadsheets, too.

Proton Scribe is listed as an add-on with a free trial, but its price is not published. Check the checkout page before committing: the annual rates are monthly equivalents, and the listed yearly totals are paid annually.

The published materials do not explain how to import files, export an account, or migrate folder structures, so we can’t put a reliable time or effort estimate on switching. Before moving a large library, confirm how you can download your files and whether your current folders and sharing arrangements can be preserved. Proton’s homepage says Drive supports secure file sharing and access across devices, but that does not establish how a migration works.

Storage is the clearest switching constraint in the published details: Free tops out at 5 GB, Mail Plus at 15 GB, and Unlimited at 500 GB. The review brief also flags mobile file search and the maturity of the official Linux client as concerns, so check those against your everyday workflow before moving.

No Reddit posts or comments were supplied, so we can’t attribute specific reasons for leaving to Reddit users. Standalone Drive pricing is also not published, which makes a direct cost comparison harder.
