# In-memory storage driver (Testing Only)

For purely tests purposes, you can use the `inmemory` storage driver. This
driver is an implementation of the `storagedriver.StorageDriver` interface which
uses local memory for object storage. If you would like to run a registry from
volatile memory, use the [`filesystem` driver](filesystem.md) on a ramdisk.

**IMPORTANT**: This storage driver *does not* persist data across runs. This is why it is only suitable for testing. *Never* use this driver in production.
