Pick Cubbit if

- Too light for anyone who wants listed integrations, as none are named
How we grade them
| 2.0GPABackblaze B2Fair | 1.8GPACubbitWeak | |
|---|---|---|
| Value for money | C$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. | C€4.99 a TB a month for 3 to 10 TB, which is cheap per terabyte, but the free and low rates are for Composer, where you run the nodes yourself. Hosted DS3 Cloud has no published price. |
| Free plan and trial | CThe first 10 GB is always free, with free egress up to 3 times what you store, and you'll pass 10 GB quickly. | CComposer is free up to 3 TB, but you need your own Linux machine for it. The hosted cloud gets a 30-day, 1 TB demo and no credit card is needed. |
| Features | CStorage through an S3-compatible API with lifecycle and partner integrations, but the page shows no consumer sync app. It does its narrow job fully. | CS3 compatibility, geo-redundancy and a flat rate with no egress or API fees. It's an object store for IT teams, not a file sharing or sync tool. |
| Ease of use | DIt needs an API, keys and tooling, so it's a developer service. No store rating on record. | DComposer nodes need a Linux machine with at least 1 vCore and 2 GB of RAM per drive. No rating on record. |
| Platforms and integrations | BThe vendor lists 8 integrations and an S3 API, but it is web only, with no apps. | CWeb console and an S3 API only. The listing names no integrations and no apps. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
