Proton Drive or kDrive: which should you choose?

Proton Drive for maximum privacy: end-to-end encryption, nobody but you reads your files. kDrive for volume and comfort: 15 GB free, 3 TB at a low price, built-in office suite. Two Swiss clouds, two philosophies, a choice based on your priorities. The full step-by-step method is in chapter 6 of my book, Vivre sans Google.

It’s the same duel as for email: Proton versus Infomaniak, maximum encryption versus Swiss comfort. You may have read the Proton Mail vs Infomaniak Mail episode; on the cloud side, the roles don’t change. Proton Drive locks your files end to end, kDrive offers much more space for less money, with a built-in office suite. So, a safe or a big house?

What Proton Drive does better

Privacy, unconditionally. Encryption happens client-side: your files leave your machine already locked, and nobody but you can open them, not even Proton. For tax notices, ID scans or a medical file, it’s the strongest guarantee there is. kDrive protects your files with Swiss law, but without end-to-end encryption.

Integration plays too. If your emails are already at Proton, storage lands in the same account, with the same subscription and the same logic. One more brick in an already encrypted ecosystem.

What kDrive does better

Volume, clearly. Count 15 GB free versus 5 at Proton, and above all 3 TB at €4.99/month where Drive Plus stops at 200 GB for €3.99/month. For a family that stores a lot, the difference shows on the bill fast.

Then office work. kDrive includes an Office-compatible suite, where Proton has no full equivalent to Google Docs yet. Do you regularly work with others on documents? kDrive comes closest, with a logic very close to Google’s. My formula for deciding: Proton protects the content, Infomaniak protects the context.

The real cost of switching

The method is the same either way: export your files from Google Drive, then upload them to the new one. At Proton, there is no automatic import for now; plan for time if your archives are heavy. I emptied my Google Drive in two weeks, one folder per evening. The pace matters little, the direction is what counts. The detailed steps are in the guide to leaving Google Drive.

Verdict

Choose Proton Drive if your sensitive documents come first. Client-side encryption is non-negotiable, and it’s the replacement I recommend over Google Drive.

Choose kDrive if you’re after space, an office suite and a familiar feel, all under Swiss law. You already gain the essential: getting your files out of the advertising economy.

This topic is chapter 6 of my book

It answers these questions, among others:

  • how do you move out cleanly, whether you pick Proton Drive or kDrive?
  • why are Google Docs the real trap of the move?
  • and what do you gain by adding a NAS at home?

Frequently asked questions

Are Proton Drive and kDrive free?

Yes. Proton Drive offers 5 GB free, then 200 GB at €3.99/month with Drive Plus billed annually. kDrive gives 15 GB free with my kSuite, and the Solo plan goes up to 3 TB for €4.99/month billed annually.

Is kDrive end-to-end encrypted?

No. Files are hosted in Switzerland and protected by Swiss law, but without end-to-end encryption: that's the big difference with Proton Drive, which encrypts client-side before upload. In exchange, kDrive offers a built-in, Office-compatible office suite.

Can you work together on documents with these clouds?

kDrive includes an Office-compatible office suite, which makes it the better fit for working together. Proton Drive has no full equivalent to Google Docs yet: it excels at private storage, less at collaborative editing.
