Persistent storage

Foundry does not charge for ingress, egress, or network bandwidth

While each instance comes with its own ephemeral storage (see details in Instance types & specifications), persistent storage provides a more reliable solution for storing critical, long-lived data and is preferable in cases where:

• You would otherwise pay significant egress costs to consistently stream data from a third-party provider.

• Your workloads would be accelerated by colocating your data.

• You are running training workloads on spot instances and need to checkpoint to mitigate the risk of preemption.

Foundry offers two options for persistent storage:

File shares

File share storage provides you with a preformatted disk for file storage. This option is best for most use cases.

Block storage

Block storage is an advanced option which provides you with a raw disk volume, giving you complete control over the filesystem.
