Our AI customers have rigorously tested B2. In their own words: “B2 was literally the only technical thing we used in training these models that didn’t crash the first time we tried it.” - Decart
B2 makes object storage pricing easy to understand and predict to help avoid surprise charges. Pricing includes 3x free egress. Update datasets in real time without upload or early deletion fees.
Unlock terabit speed at exabyte scale for performance-critical AI applications that require dedicated storage vaults and networking resources–plus all-inclusive free egress and API transactions.
Skip ticket queues and endless escalations. Backblaze’s human-powered support team of storage specialists provide technical expertise when you need it most.









Backblaze B2 offers high-performance, S3-compatible cloud storage designed for machine learning and high-performance computing (HPC) workflows. It keeps training sets, model checkpoints, and inference data always accessible, helping you iterate faster without spiraling costs.
Yes. With Backblaze B2, you’re free to pair your data with any HPC or GPU provider that meets your needs. Thanks to our egress-friendly model, shifting workloads between different compute environments won’t lead to unexpected fees.
Absolutely. B2 Cloud Storage is built for substantial datasets in AI, ML, and HPC contexts—ideal for hosting your training data, versioned models, and archival datasets. While compute-intensive training typically runs on dedicated GPU clusters, Backblaze B2 reliably stores the inputs and outputs that power them.
Yes. Our Technology Partners ensure seamless integration with popular ML and HPC tools. And, with full S3 API compatibility, you can plug Backblaze B2 into your current pipelines with minimal setup.
We employ industry-standard security measures, including two-factor authentication and server-side encryption (SSE), plus SOC-2 compliant data centers offering 11 nines of durability. You retain full control over your data—encryption keys remain yours, and no one else can access your stored information.
Backblaze B2 excels in diverse scenarios like e-commerce, gaming, large-scale enterprise apps, and AI/ML workloads. Whether you’re training neural networks or running a high-throughput HPC pipeline, its scalable and cost-efficient architecture fits a range of performance needs.
B2 Overdrive is built on the foundation of B2, but with additional networking capacity that can reach up to 1Tbps throughput. B2 Overdrive has designated storage and networking resources walled off from other Backblaze infrastructure to support maximum performance for performance-sensitive workloads.
