CoreWeave signs a $335M storage agreement with Backblaze. Its Alpha Score (19/100, Weak) raises questions about execution and single-vendor dependency. The multi-exabyte deal locks in HDD storage for five years.

CoreWeave signed a $335 million, five-year agreement with Backblaze to store multi-exabytes of data on Backblaze's HDD-based cloud storage. The deal covers portions of CoreWeave's managed storage infrastructure, freeing up high-performance resources for AI workloads.
Backblaze will provide the slower, cheaper HDD tier for CoreWeave's AI Object Storage. Customers using CoreWeave's LOTA distributed cache get access to the new tiers without code changes. For CoreWeave, the agreement locks in a single storage vendor for a key piece of its infrastructure.
The company's Alpha Score, a proprietary AlphaScala measure of fundamental and technical health, stands at 19 out of 100, the Weak category. That score points to financial or operational strain. Tying a multi-exabyte storage pipeline to a single provider adds concentration risk.
CoreWeave could mitigate that risk by maintaining parallel storage options or structuring the contract with early exit clauses. The press release did not mention either. If Backblaze experiences outages or performance issues, CoreWeave's AI customers could see delays. The deal's five-year lock-in could become a liability if storage needs shift or if Backblaze's pricing changes.
Backblaze, with more than 100,000 customers, has a track record of large-scale HDD storage. The company went public in 2021 and has been expanding enterprise features. Its revenue growth has been steady but not explosive. The agreement is effective immediately. No timeline was given for full deployment.
"Backblaze has built a reputation for making complex, HDD-based storage infrastructure reliable and easy-to-consume at scale," said Nick Hoover, a CoreWeave vice president. The deal was announced in a press release. CoreWeave's stock page shows its current AlphaScala metrics.
