Our verdict

com wins if you only want storage and Proton Drive wins if you want the rest of the suite with it. com Solo Basic gives 2 TB at $8 a month, $96 a year, and scores 4.5. Proton Unlimited is $9.99 a month, $119.88 a year, and scores 4.4.

That is $23.88 a year more at Proton, and the storage it buys is smaller. The reason to pay it is that Proton Unlimited is not a storage plan: it includes Proton Mail, VPN, calendar and password manager under the same subscription.

If you were going to pay for any two of those separately, the maths flips immediately. Both are zero knowledge, meaning the provider cannot read your files, and both have free tiers to try first.

com is the ecosystem: it does storage and sharing well and nothing else, and the desktop app is plainer than the competition. The honest downside of Proton Drive is that the storage component is the youngest part of the suite and still behind on features like selective sync and third party integrations.

com, and save $23.88 a year. You already pay for a VPN or a private mailbox: Proton Unlimited, and cancel the other subscription.

The encrypted all-rounder: zero-knowledge by default, generous versioning, fair prices, and none of the usual privacy tax on usability. For most people who want their files private without thinking about it, this is the one.Editorial team, on Sync.com
The privacy ecosystem play: zero-knowledge encryption by default, Swiss jurisdiction, and it comes bundled with the best private email and a top-tier VPN. Still younger and leaner on features than the veterans, but maturing fast.Editorial team, on Proton Drive

Frequently asked questions

Which is cheaper, Sync.com or Proton Drive?

Sync.com. Solo Basic is $8 a month, $96 a year for 2 TB, against $9.99 a month, $119.88 a year for Proton Unlimited, a difference of $23.88. Proton bundles mail, VPN, calendar and a password manager into that price, so compare it against what you already pay for those.

Can either provider read my files?

No. Both use zero knowledge encryption, which means the keys stay on your side and the provider stores data it cannot open. The practical consequence is the same at both: lose your password and the recovery options are limited, because there is no back door for support to use either.

Can I try them before paying?

Yes, both have a free tier. That is the sensible way to settle this, because the difference people actually notice is the desktop app and how sync behaves with the folders they really use. A week of ordinary work tells you more than any feature table.
