Sync.com

6.8 / 10

Sep 5, 2026

End-to-end encryption as the default, not an add-on

1 TB of end-to-end encrypted storage for $6 a month with 90 days of file history.

Holds up
  • + End-to-end encryption applies to every personal plan rather than being sold as an add-on
  • + File history runs to 90 days on the 1 TB plan and 180 days on 5 TB
  • + Annual totals are printed alongside the monthly figure ($42, $72, $168)
Weigh up
  • − Neither the pricing page nor the privacy policy names the country where files are stored
  • − The word "zero-knowledge" is not used, only that the customer alone can decrypt content
  • − Sync can still see IP address and access-time metadata

pCloud

6.3 / 10

6 source documents

Sep 5, 2026

Swiss provider with a user-chosen data region

500 GB for $49.99 a year with a choice of European or US data region and an optional zero-knowledge layer.

Holds up
  • + The data region is a customer choice between Europe and the USA, stated up front
  • + $49.99 a year for 500 GB is the cheapest published per-account annual price of the consumer plans here
  • + Client-side, zero-knowledge encryption is available as an explicit add-on
Weigh up
  • − Zero-knowledge encryption is not part of the base plans and its price is not published on the page
  • − Download-link traffic is capped, and the 10 TB plan still only carries 2 TB of it
  • − The 14-day refund window is the shortest here

IDrive Personal

5.5 / 10

5 source documents

Sep 5, 2026

Backup-oriented storage at the lowest price per terabyte

5 TB for $6.99 in the first year against a $9.99 regular price — the cheapest terabyte here.

Holds up
  • + The lowest price per terabyte in this category: 5 TB for $6.99 a month in the first year
  • + The regular price is printed next to the promotional one on every tier
  • + Capacities run to 100 TB without moving to a business contract
Weigh up
  • − The pricing page states no version-history length
  • − Private-key encryption is not stated on this page, so end-to-end protection is unverified
  • − No money-back guarantee is published

Proton Drive

Proton Drive document editor supplied in its official media kit
5.2 / 10

7 source documents

Sep 5, 2026

The strongest published privacy model in the category

End-to-end encrypted storage — including file names — from a Swiss provider with audited, open-source apps.

Holds up
  • + File names as well as file contents are encrypted on the device before upload
  • + The apps are open source and independently audited, so the encryption claim can be checked
  • + Swiss jurisdiction, explicitly outside US and UK reach
Weigh up
  • − No price is present on the pricing page: the figures load from a pricing component
  • − The free tier is 5 GB, smaller than Koofr's 10 GB
  • − The cheapest paid tier is 200 GB, so there is no small, cheap step

Koofr

5.0 / 10

7 source documents

Sep 5, 2026

Small European provider with a genuinely useful free tier

A 10 GB free tier and yearly-only paid plans that start at €2 a month for 100 GB.

Holds up
  • + A 10 GB free tier, larger than most free tiers here
  • + Prices already include VAT, so the figure shown is the figure paid in the EU
  • + Connections to external clouds (9 to 30 by plan) let one account front several services
Weigh up
  • − Only yearly subscriptions are available, with no month-to-month option
  • − The pricing page names neither the data-centre location nor a jurisdiction
  • − Encryption is limited to Vault safe boxes rather than the whole account

Post-quantum encryption claim with a named auditor

Zero-knowledge and post-quantum encryption from a GDPR-based provider, audited by Securitum.

Holds up
  • + Zero-knowledge encryption is the default on every plan, not an add-on
  • + The auditor is named (Securitum), so the claim can be checked
  • + Linux, Windows, macOS, Android, iOS and web clients
Weigh up
  • − No price is present on the pricing page: every figure renders as a €0 placeholder
  • − The free tier is only 1 GB
  • − No version-history length is published

Dropbox Plus

4.2 / 10

5 source documents

Sep 5, 2026

The default sync client, with compliance paperwork rivals do not publish

2 TB with 30 days of file recovery and published SOC and GDPR compliance, at $9.99 a month.

Holds up
  • + Publishes SOC 1/2/3, GDPR and HIPAA support, which most consumer rivals here do not
  • + Dropbox Rewind can roll an entire folder or account back after a ransomware event
  • + Transfers up to 50 GB and unlimited linked devices
Weigh up
  • − No client-side encryption: Dropbox holds the keys to the files at rest
  • − $9.99 a month for 2 TB is roughly double the per-terabyte price of the cheapest providers here
  • − No yearly price is published on the plans page, so the annual discount is unknown
End-to-end encryption
No

Backblaze Personal Backup

3.8 / 10

6 source documents

Sep 5, 2026

Unlimited capacity, priced per computer instead of per terabyte

Unlimited backup for one computer at $99 a year, with a free mailed hard-drive restore.

Holds up
  • + Capacity is unlimited, so a large photo or video library costs the same as a small one
  • + A private encryption key is offered, which makes the account effectively zero-knowledge
  • + Free mailed hard-drive restore, which matters when recovering terabytes
Weigh up
  • − Priced per computer, so a household with three machines pays three times
  • − Only Windows and macOS clients; no Linux, Android or iOS backup
  • − The standard version-retention length is not stated; "forever" costs extra

Microsoft 365 Personal (OneDrive)

3.4 / 10

6 source documents

Sep 5, 2026

Storage bundled with the Office applications

1 TB of OneDrive plus the desktop Office apps for $99.99 a year — or 6 TB across six people for $129.99.

Holds up
  • + The Family plan divides to about $21.67 per person per year for 1 TB each, the cheapest per-person terabyte here
  • + The desktop Office applications are included, so the storage is effectively a by-product
  • + Both monthly and yearly prices are published for every tier
Weigh up
  • − Storage cannot be bought without the application bundle
  • − The comparison page states no encryption model, version history or data region
  • − 1 TB per person is a hard ceiling; there is no larger consumer tier

Sep 5, 2026

Consumer entry point to an enterprise content platform

100 GB with a 5 GB file-size limit and built-in Microsoft 365 and Google Workspace integration.

Holds up
  • + A 10 GB free tier with two-factor authentication included
  • + Microsoft 365 and Google Workspace integrations are built in rather than bolted on
  • + The 5 GB upload limit on Personal Pro suits large design and video files
Weigh up
  • − The Personal Pro price is not present in the pricing page as served
  • − 100 GB is small next to rivals charging similar money for terabytes
  • − The page states no encryption model, data region or money-back policy

Methodology

How We Chose

Scores are calculated from the facts published on each provider's own plan or security page, using the same checklist for every product:

  • Price transparency (0-2) — is a price published on the plan page at all, and is the unit (per account, per person, per computer) clear? A provider whose figures render only in a store component scores lowest.
  • Capacity for the money (0-1.5) — storage per dollar at the compared tier, or unlimited capacity.
  • Encryption model (0-2.5) — end-to-end or zero-knowledge encryption by default scores highest, an optional client-side layer next, server-side encryption alone lowest. Encrypting file names as well as contents scores above encrypting contents alone.
  • Independent verification (0-1) — a named auditor, a published certification (SOC, ISO) or an open-source client.
  • Version history and recovery (0-1.5) — how far back a file can be restored, and whether a bulk restore path exists.
  • Jurisdiction and data region (0-1) — whether the provider states where files are stored and under which law.
  • Refund window (0-0.5) — the money-back period the provider states.

Points are lost for facts a provider does not publish. We did not measure upload or download speed: this is a documentation-based comparison of what you can verify before you pay, and every claim links to the page it came from.
