Frequently Asked Questions
Everything you need to know about cloud storage economics, encryption, and contract terms.
What is the cheapest cloud storage per TB in 2026? +
As of 2026, the cheapest cloud storage per terabyte is IDrive (often under $1.00/TB/month on introductory plans) and Backblaze B2 ($6.00/TB/month pay-as-you-go). For long-term personal sync storage, pCloud's lifetime plans offer the lowest total cost of ownership after 2.5 to 3 years.
How does CostRatio calculate $/TB/month? +
We divide the monthly price of each plan by its storage volume in gigabytes and multiply by 1,000 to normalize to a standard 1TB benchmark. For annual or multi-year subscriptions, we divide by the contract period to reflect the true monthly cost.
Which cloud storage providers offer zero-knowledge encryption? +
Sync.com, MEGA, Tresorit, and Proton Drive offer native end-to-end zero-knowledge encryption across all plans. pCloud offers zero-knowledge encryption via its Crypto add-on. Mainstream services like Google One, Dropbox, and iCloud encrypt data in transit and at rest, but retain encryption keys on their servers.
What are cloud storage egress fees? +
Egress fees are charges for downloading or transferring data out of an object storage provider. While consumer sync services like Google One include unlimited download bandwidth, object storage services like AWS S3 charge up to $0.09/GB. Services like Wasabi and Cloudflare R2 charge $0 for egress, making them dramatically cheaper for active data workloads.
