# Ephemeral storage Each instance comes with its own ephemeral storage (outlined in [Instance types & specifications](/compute-and-storage/instance-types-and-specifications.md)), usually with NVMe SSD. This storage will exist until the instance has been terminated or pre-empted. There is no cost to use the ephemeral storage. Ephemeral storage is automatically mounted for you (and re-mounted after preemptions) at `/mnt/local`. When you perform a VM restart, ephemeral storage will be retained. However, should the VM host (i.e., server) restart due to maintenance or support, ephemeral storage is wiped.

Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.mithril.ai/compute-and-storage/ephemeral-storage.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
