Quick take

Both are consumer zero-access clouds. Proton Drive wins this pairing if you want Mail, VPN, and Pass in the same company. Sync.com wins this pairing if you want a storage specialist with a long encrypted-sharing reputation. Confirm current GB and prices. This page does not rank pCloud, MEGA, or Google.

Why people put these two in the same sentence

Once you decide the host should not hold keys, the shortlist is small. Proton Drive and Sync.com are the names that show up. Both encrypt on the device. Both offer sharing that fits that model. The fork is ecosystem vs specialist, plus price for the GB you actually need. This article ranks only these two.

Not a site-wide encrypted-cloud trophy. Other vendors are not scored here.

  1. 1

    Proton Drive

    4.7

    Wins this pairing when you already want Proton Mail/VPN/Pass, Swiss jurisdiction as a story, and Docs/Sheets in the same login.

  2. 2

    Sync.com

    4.6

    Wins this pairing when you want a Canada-based encrypted-storage specialist and you will not use Proton's other apps.

    Drive-first E2E storage

What both get right

Client-side encryption, a modest free tier (both commonly 5 GB), paid personal plans, sharing with controls, and a story aimed at people who left Google. Neither makes you anonymous. Neither survives a bad password. Both beat a random 'lifetime 90% off' disk that has no audit trail.

Where they split

Proton is a suite company: Drive plus Mail, VPN, Calendar, Pass, with Swiss jurisdiction and open-source clients Proton emphasizes. Sync.com is a storage company: encrypted sync and sharing as the whole product, with its own plan ladder (often cited around a few dollars more per month at similar GB — confirm live). If you will never touch Proton Mail, you might be paying Proton for a brand you wanted, not a feature you use — unless Drive Plus is the SKU, which is storage-first.

Collaboration: Proton has Docs and Sheets. Sync.com has been the 'encrypted Dropbox' analog for longer in many reviews. Desktop and mobile exist on both; check the OS you actually run. GUIDEORA will not invent a speed-test winner; encryption overhead and your ISP dominate anecdotes.

How to choose in this pairing

If Proton is already your email or VPN, Drive is the consistent next room — Plus or Unlimited depending on GB. If you only need an encrypted disk in the sky, price Sync.com's current personal plan next to Drive Plus and pick the checkout that matches OS and sharing.

Editor take

Suite vs specialist

Want one privacy vendor: Proton Drive (especially Unlimited). Want a drive-first encrypted product: price Sync.com's current personal plans next to Drive Plus.
