Publisher review
Wasabi Fire is a high-performance cloud object storage class introduced by Wasabi in late 2025, built on NVMe SSD media to deliver single-digit millisecond response times for compute-intensive AI and ML training workloads. It targets organizations that need faster data access than standard cloud storage, such as those training large language models or running real-time inference pipelines. Wasabi Fire is priced at $19.99 per TB per month with no egress fees, offering a flat-rate alternative to AWS S3 Express One Zone or other high-speed tiers. The service is designed for users who require both high throughput and low latency without the complexity of provisioning dedicated infrastructure.
Wasabi Fire leverages NVMe flash storage to achieve read and write speeds approximately five times faster than Wasabi's standard Hot Cloud Storage class, which uses HDD-based media. It maintains S3 API compatibility, allowing existing applications and tools to connect without modification. The storage class provides 11 nines (99.999999999%) data durability through erasure coding and replication across multiple availability zones. Wasabi Fire supports AI workloads with consistent sub-10-millisecond latency, making it suitable for checkpointing, dataset loading, and model serving. The service includes Wasabi's flat-rate pricing model, meaning there are no charges for data retrieval or egress, only storage and API request costs.
Wasabi competes directly with AWS S3 Express One Zone, Google Cloud Storage's high-performance tiers, and Azure Blob Storage premium offerings. Wasabi Fire is priced at $19.99 per TB per month, which is roughly 60% less than AWS S3 Express One Zone's $0.16 per GB per month ($163.84 per TB per month) for comparable NVMe-based performance. Unlike Backblaze B2, which focuses on backup and archive use cases with lower performance, Wasabi Fire targets active AI and ML workloads. Wasabi's standard Hot Cloud Storage class at $5.99 per TB per month competes with AWS S3 Standard and Backblaze B2 on price, but Fire is positioned as a premium tier for latency-sensitive applications.
The primary trade-off with Wasabi Fire is its higher per-TB cost compared to Wasabi's Hot Cloud Storage ($5.99/TB/month), making it less economical for cold data or archival storage. Users must manage encryption keys separately for advanced encryption, as Wasabi does not provide integrated key management. Some community reports indicate reliability concerns compared to AWS S3, though Wasabi's durability claims are high. Wasabi Fire also lacks backup-specific features like versioning or lifecycle policies that Backblaze B2 offers, so it is best suited for performance-critical workloads rather than general backup.
How it works

Provides 99.999999999% data durability through erasure coding and multi-zone replication, matching enterprise-grade standards.
-
No egress fees
Charges no fees for data retrieval or transfer out, simplifying cost management for active workloads.
-
Five times faster than Hot
Delivers approximately 5x higher throughput compared to Wasabi's standard Hot Cloud Storage class, which uses HDDs.
-
Flat-rate pricing
Priced at $19.99 per TB per month with no hidden costs for API requests or data access, unlike tiered competitors.
-
Purpose-built for AI
Designed for compute-intensive tasks like model training and inference, with consistent sub-10-millisecond latency.
Strengths and trade-offs
Strengths
- Priced at $19.99 per TB per month, Wasabi Fire costs roughly 60% less than AWS S3 Express One Zone's $163.84 per TB per month for comparable NVMe performance.
- No egress fees eliminate surprise costs for data retrieval, a significant advantage over AWS S3 which charges $0.09 per GB for data transfer out.
- Achieves single-digit millisecond response times, making it suitable for latency-sensitive AI training and inference workloads.
- Provides 11 nines (99.999999999%) data durability through erasure coding, matching or exceeding the durability of AWS S3 Standard.
Trade-offs
- At $19.99 per TB per month, Wasabi Fire is over three times more expensive than Wasabi's own Hot Cloud Storage at $5.99 per TB per month for less demanding workloads.
- Does not include built-in encryption key management, requiring users to handle key rotation and storage separately for advanced security.
- Lacks backup-specific features such as versioning, lifecycle policies, and object lock, which are available in Backblaze B2 and AWS S3.
- Some Reddit community reports cite reliability concerns compared to AWS S3, though Wasabi's published durability claims are high.
Pricing context
Wasabi Fire: $19.99 per TB per month with no egress fees. Wasabi Hot Cloud Storage: $5.99 per TB per month with no egress fees. Both tiers charge no retrieval or API request fees.
Getting started with Fire
-
Sign up for Wasabi Fire
Go to the Wasabi website and create an account. During sign-up, select the Wasabi Fire storage class as your default tier. Provide your payment information and verify your email to activate the account.
-
Connect your S3-compatible tools
Use your Wasabi access key and secret key to configure any S3-compatible client, such as AWS CLI or boto3. Set the endpoint URL to Wasabi's S3 endpoint for your region. No code changes are needed.
-
Configure a bucket for Fire
Create a new bucket in the Wasabi console or via API. Explicitly set the storage class to "Wasabi Fire" to ensure all objects use NVMe-based storage. Enable encryption if required, managing keys externally.
-
Upload AI training datasets
Use your S3 client to upload large datasets, such as model training files or checkpoint data, to the Fire bucket. Expect single-digit millisecond latency and throughput five times faster than standard Wasabi storage.
-
Monitor performance and costs
Track your storage usage and API request counts in the Wasabi console. Since there are no egress fees, your monthly cost is simply $19.99 per TB stored plus request costs. Adjust bucket settings as needed.
