Storage Comparison
Edge vs Backblaze B2
A detailed comparison of Edge Storage and Backblaze B2 for object storage.
How we compare to Backblaze B2
Backblaze B2 is one of the best-value object stores around. At roughly $6 per TB per month it undercuts almost everyone on raw storage cost, and it's a superb choice for backups, archives, and cold data. Credit where it's due: if you're storing a lot and downloading a little, B2 is very hard to beat.
Edge Storage is built for a different job: hot data that gets served. Egress is free without conditions — B2's free egress is capped at 3x your stored data, after which per-GB charges apply. Reads are always free on Edge, storage is all-NVMe, and edge caching is included rather than routed through partner CDNs.
Both offer S3-compatible APIs, so tooling works either way. Choose based on workload: B2 for cold archives, Edge for data your users actually download. See our pricing and the getting started guide.

An Honest Look at the Pricing
Which is cheaper depends entirely on how your data is used.
B2 wins on cold data
At roughly $0.006/GB stored, B2 is less than half Edge's $0.013/GB. If you're storing backups or archives that are rarely downloaded, B2 will likely cost less overall. We'd rather tell you that than have you find out later.
Edge wins on hot data
Once downloads exceed 3x your stored data, B2 starts charging per GB — and content, media, and app assets routinely blow past that ratio. On Edge, egress is $0 no matter how much you serve, reads are free, and edge caching is built in. The busier your data, the further ahead Edge pulls.
When to Choose Edge
B2 is excellent for archives. Here's when Edge makes more sense.
Your data is downloaded heavily
B2's free egress stops at 3x your stored data — a problem for small datasets served often. Edge egress is free without conditions.
You serve users, not archives
Edge Storage runs on NVMe with integrated edge caching, built for hot data. B2 is optimised for backup and archival workloads.
You want one platform
B2 is storage only. Edge pairs buckets with VMs, a global CDN, and DNS under one account and one bill.
