Why Backblaze B2 gets a 2.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for money$6.95 per TB a month matches the category's middle price. This is a different kind of product from consumer storage, billed by the terabyte.
- CFree plan and trialThe first 10 GB is always free, with free egress up to 3 times what you store, and you'll pass 10 GB quickly.
- CFeaturesStorage through an S3-compatible API with lifecycle and partner integrations, but the page shows no consumer sync app. It does its narrow job fully.
- DEase of useIt needs an API, keys and tooling, so it's a developer service. No store rating on record.
- BPlatforms and integrationsThe vendor lists 8 integrations and an S3 API, but it is web only, with no apps.
