* Proton Drive's free tier caps at 2 GB by default — the full 5 GB requires completing three setup tasks (add a file, create a share link, add a recovery method) within 30 days.
* "Unlimited" is a full Proton bundle (Mail + VPN + Pass + Calendar + Drive), not a Drive-only plan — you're paying for more than storage.
* Proton Drive offers genuine end-to-end (zero-knowledge) encryption, which WarpStash does not have yet.
Where Proton Drive wins
- Zero-knowledge end-to-end encryption — Proton literally cannot read your files. WarpStash currently uses server-side encryption at rest, not E2EE.
- Bundled with Proton's other privacy tools (Mail, Pass, Calendar) if you want a full suite.
Where WarpStash wins
- Meaningfully cheaper per GB — WarpStash Plus (500 GB, $4.92/mo billed annually) costs slightly more per month than Proton's 200GB Drive Plus ($3.99/mo billed annually), but for 2.5x the storage — about half the price per GB.
- Explicit, generous transfer allowances built into every tier, not just storage.
