* 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.
* WarpStash's Vault mode (opt-in, per account) encrypts file names, folder names, and contents; Proton Drive's E2EE is on by default and covers the same ground, but can't be turned off even for files you don't need it on.
Where Proton Drive wins
- End-to-end encryption on by default, with no setup step; WarpStash's Vault is opt-in, so you choose which buckets get it.
- 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 (1TB/$4.92/mo billed annually) costs less than Proton's 200GB Drive Plus plan while offering 5x the storage.
- Explicit, generous transfer allowances built into every tier, not just storage.
- Free Vault mode (names, folders, and contents encrypted) on every plan, not locked behind a pricier bundle, and optional rather than all-or-nothing.
