Three private surfaces. Same zero-knowledge architecture.
Comparison
| Criterion | Google Drive | Zero-knowledge storage |
|---|---|---|
| Where files are encrypted | On the provider's servers | On your device, before upload |
| Who holds the key | The provider | You |
| Provider can read files | Technically yes | No |
| Full-text search | Server-side, excellent | Blind indexes computed on device |
| Previews and thumbnails | Server-generated, universal | Rendered client-side |
| Real-time co-editing | Mature | Limited by design |
| Sharing links | Provider-managed, long-lived by default | Key in URL fragment, passphrase, enforced expiry |
| Password reset restores data | Yes | No — recovery kit required |
| Breach of provider exposes | Readable content | Ciphertext |
| Legal request to provider yields | Content | Metadata |
Why the trade-offs are real, not marketing Every convenience in the left column is downstream of one fact: the server can read the file. You cannot keep the conveniences and remove the fact. Vendors that claim both are usually encrypting *some* fields, or holding keys "on your behalf".
Choosing by data type - **Public and low-sensitivity material:** the mainstream suite is genuinely better. - **Confidential client and business data:** zero-knowledge, without hesitation. - **Regulated personal data:** zero-knowledge, plus documented access controls and audit logging. - **Archive and long-term retention:** zero-knowledge with independent encrypted backups.
What a good zero-knowledge product still gives you Fast uploads that resume after a crash; client-side previews for common formats; galleries for photos; encrypted ZIP downloads for bulk retrieval; search that finds a file by name and tags without a server seeing either; team folders whose keys are sealed per member; and short-lived external links.
Where DRIVUNO sits Argon2id key derivation on device, X25519 per-member key wrapping, XChaCha20-Poly1305 payload encryption, HMAC blind-index search, resumable verified chunked uploads, per-member sealed Team Drive folder keys with rotation on removal, a maximum 24-hour lifetime on every public link, and hourly encrypted snapshots to independent immutable storage.
The decision in one sentence If losing control of a file would cost you a client, a case or a contract, choose the option where losing control is not technically available to anyone.
