Learn about CoreWeave Storage options
CoreWeave Cloud Storage Volumes are built on top of Ceph, a software defined scale-out enterprise grade storage platform. Built with triple replication, the CoreWeave Cloud Storage platform is built to provide high-availability, performant storage for your most demanding Cloud-native workloads.
Accessible by both containerized and hypervisor Workloads
Easily resized to add more capacity at any time
Single Storage Volumes can be scaled to the multiple Petabyte level
Easily managed from the CoreWeave Cloud UI or via
May be cloned to instantiate new Virtual Servers from a template
There are certain exceptions to this rule of thumb, which are mainly relevant for shared volumes, such as:
- Batch Workloads where IOPS are not a concern but accessing compute capacity from multiple regions might give scaling benefits
- When data is strictly read during startup of a process, such as when reading a ML model from storage into system and GPU memory for inference
In general, block volumes should always be used in the same region in which they are allocated.

Block Storage Volumes are attached to containerized workloads and Virtual Server instances as high-performance virtual disks.
When served from our all-NVMe storage tier, these virtual disks readily outperform local workstation SSDs, and are scalable to the Petabyte scale. These volumes are presented as generic block devices, so they are treated by the operating system like a typical physically connected storage device.
POSIX-compliant Shared File System Volumes can be attached to both containerized and Virtual Server workloads to provide native shared file systems.
It is possible to attach these Volumes to many instances at the same time. They are great for centralized asset storage, whether for sharing with co-workers in the cloud or as a data source for massively parallel computation.
The All-NVMe CoreWeave Cloud storage tier offers the highest performance in both throughput and IOPS.
Great for hosting the root disk of a Virtual Server, or as the backing store for a transactional database, the All-NVMe tier can provide up to 10 million IOPS per Volume and peak storage throughput into the Tbps range.
The HDD CoreWeave Cloud storage tier offers excellent throughput optimized performance at a lower cost.
Great for large file storage with sequential IOPS access patterns, the HDD tier is backed by an NVMe caching layer to improve performance and scale throughput capacity.
All physical nodes are equipped with SSD or NVMe ephemeral (local) storage. Ephemeral storage available ranges between
2TB, depending on the node type. No Volume Claims are needed to allocate ephemeral storage - simply write anywhere in the container file system.
Storage is billed per gigabyte of allocated (requested) space as an average over a billing month.
