“From a cost of goods sold perspective, AWS pricing wasn’t a great fit. Backblaze was a drop-in API replacement with a much better cost structure—it was just a no-brainer.”

Backblaze focuses on reliable, always-hot object storage for top use cases, not pricey bells and whistles for outlier needs.
Backblaze innovated on commodity hardware with intelligent software for high performance without high cost.
Backblaze plans, buys, codes, and operates our storage cloud for cost efficiencies at exabyte scale.
Backblaze B2 Overdrive is a high-throughput cloud object storage solution, engineered for workloads needing rapid data access. Built on top of Backblaze B2, pricing starts at $15 per TB/month for increased storage and networking throughput, and includes unlimited free egress to facilitate intensive data operations without prohibitive costs.
B2 Overdrive is specifically designed for organizations with demanding, throughput-intensive applications like AI/ML training and inference, high-performance compute (HPC), large-scale data analytics, media processing pipelines, and research compute.
Service is billed monthly, based on the amount of data stored per byte-hour over the last month at a rate of $6/TB/30-day.
Backblaze B2 offers unlimited free egress when downloading to or through partner content delivery networks (CDNs) and compute services, including Fastly, Cloudflare, bunny.net, CacheFly, CoreWeave, Equinix Metal, Vultr, and phoenixNAP. Additionally, B2 Overdrive includes unlimited free egress to any destinations, supporting throughput-intensive workloads.
All Backblaze B2 Cloud Storage users enjoy free data egress (also known as download) up to 3x their average monthly storage amount. The monthly average is determined based on byte hours over the billing cycle, with total egress up to 3x the average provided free.; Egress exceeding this amount is priced at $0.01/GB.
The comparison charts are accurate based on published rates and select assumptions at the time of the publication. Of course, every business’ scenario is a little different so it is wise of you to apply further diligence based on your data set, workflow, and needs.
Both services run on the same highly performant platform. Which is better for you will depend on how you wish to operate. Pay-as-you-go is ideal for flexible scaling, monthly billing, or smaller data needs. B2 Reserve is suited for businesses seeking consistent annual billing and larger storage commitments starting at 20TB, often purchased through resellers or integrators.
Backblaze B2 is built for affordable performance. We focus on delivering always-hot service for top use cases, rather than adding expensive bells and whistles for outlier needs. We marry open source and commodity hardware with our intelligent software for high performance without high cost. And, we operate at exabyte scale for cost efficiencies.
High-performance, S3-compatible cloud storage, purpose built to provide simplicity, reliability, and affordability.
B2 Cloud Storage is the scaleable, proven, secure solution for your data storage needs that is just a fraction the rates of other cloud providers. Let us know how we can help you.
