Cloud storage is where most of us keep our real digital lives now, yet people often pick a service by accident (whatever came with the phone) and overpay or lose privacy without realising. We compared the big five on the numbers that matter, and flag one dangerous misconception at the end.
The contenders and what they cost
| Service | Free tier | Paid (2026, ~) | Best for |
|---|---|---|---|
| Google Drive | 15 GB | 100 GB ~$2/mo, 2 TB ~$10/mo | Docs, sharing, Android |
| iCloud | 5 GB | 50 GB ~$1/mo, 2 TB ~$10/mo | Apple devices, photos |
| Microsoft OneDrive | 5 GB | 1 TB with Microsoft 365 ~$70/yr | Office users, Windows |
| Dropbox | 2 GB | 2 TB ~$12/mo | Fast sync, cross-platform teams |
| pCloud | Up to 10 GB | Lifetime plans; optional zero-knowledge | Privacy, one-time payment |
Price per terabyte, honestly
Once you need real space, the market clusters around 2 TB for roughly $10 a month (Google, iCloud, Dropbox). The value outlier is OneDrive: a Microsoft 365 subscription bundles 1 TB with the full Office suite for about $70 a year, which is hard to beat if you use Word and Excel anyway. If you dislike subscriptions entirely, pCloud’s lifetime plans are a genuine alternative.
Privacy: the part people skip
Most mainstream services can technically read your files (they hold the keys), which is fine for holiday photos and awkward for sensitive documents. If privacy is a priority, look for zero-knowledge (end-to-end) encryption, where only you hold the key. pCloud offers it as an add-on, and Proton Drive and Sync.com build their whole product around it. The trade-off is fewer collaboration features — the provider genuinely cannot help you if you lose the key.
The misconception that costs people their files
The most important thing in this article: cloud sync is not a backup. Services like Drive and Dropbox mirror your files — so if you (or ransomware) delete or corrupt a file, that deletion syncs everywhere within seconds. A real backup keeps independent, versioned copies you can roll back to. Use cloud storage for access and sharing, but keep a separate proper backup as well — the two jobs are different, and confusing them is how people lose years of photos.
Frequently asked questions
Is cloud storage the same as a backup?
No. Sync services mirror changes instantly, so a deletion or corruption spreads everywhere. A real backup keeps independent, versioned copies you can restore from.
What is the cheapest way to get 1 TB or more?
A Microsoft 365 subscription bundles 1 TB of OneDrive with Office for about $70/year. For 2 TB, Google, iCloud and Dropbox sit around $10/month.
Which cloud storage is most private?
Look for zero-knowledge encryption where only you hold the key — Proton Drive, Sync.com, or pCloud's encrypted add-on. Mainstream services can technically read your files.
How much free cloud storage can I get?
Google Drive offers 15 GB free, the most among the big services; iCloud and OneDrive give 5 GB, Dropbox 2 GB.
