CoreWeave launches S3-compatible Object Storage at $0.03 per GB per month
CoreWeave has introduced CoreWeave Object Storage, an S3-compatible service priced at $0.03 per GB per month with no access or transfer fees. According to the company, the service is available in all CoreWeave data center regions and is currently in beta.
- CoreWeave Object Storage costs $0.03 per GB per month, with no operation or egress fees.
- The service is S3 compatible and includes encryption at rest (SSE).
- An optional NVMe accelerated cache supports multiple terabits per second of throughput.
- It is available in all CoreWeave data center regions and is currently in beta.
- CoreWeave compares the price with $0.04 per GB per month for HDD block and shared file system storage.
What CoreWeave is offering
CoreWeave Object Storage is designed for clients who want to store and retrieve large volumes of unstructured data. The company says it is meant for asset data, static files, metadata and other files that do not fit well into block or shared file systems. Customers pay only for what they store, and no resizing is needed.
The service is S3 compatible, which CoreWeave says means it follows the S3 standard and works with existing S3 client libraries and SDKs. Data is accessed over HTTPS, either through any S3 compatible SDK or with simple tools such as curl. The API includes encryption at rest (SSE).
CoreWeave also says the service integrates with existing AI/ML applications and data storage products, naming LucidLink and Weka. It positions the offering as simpler access for users who do not want or need a shared file system.
The company points to two example uses. VFX studios can keep static assets and metadata in cloud native production pipelines, and Pixel Streaming customers can store game data and other items needed when they spin up new clients.
Regional design and the accelerated cache
CoreWeave contrasts its approach with AWS, which it says imposes a global uniqueness constraint on bucket names. CoreWeave Object Storage instead uses independent clusters, so users can create identical buckets in each region and may use any regional endpoint.
An optional NVMe accelerated cache is aimed at performance. According to CoreWeave, the Accelerated Cache for Object Storage improves read throughput, latency and overall application performance, and supports multiple terabits per second of throughput with auto scaling. The company says NVMe-backed regional caches allow fast data pulls from any CoreWeave data center region.
As a result, clients do not need to deploy in the same region where their data is stored. CoreWeave credits its HPC networking for giving them instant, scalable access from any region.
Pricing and availability
The headline price is $0.03 per GB per month. CoreWeave compares this with $0.04 per GB per month for its HDD block and shared file system storage. The company says it does not charge for access to the service, only for stored data, with no operation fees and no egress fees.
CoreWeave summarizes the benefits as scalability without limits, faster data retrieval and more flexibility, and lower storage costs with no hidden fees. The service is currently in beta. Interested customers can consult the Object Storage Documentation or contact the CoreWeave team to get started.
For teams already running AI, HPC or enterprise workloads on CoreWeave Cloud, the offering adds a lower-cost storage tier that avoids transfer charges. Since it is a beta product, the details described in the announcement may still change.
