Persistent storage is a data storage within a device that retains the data even when the device is offline.
Persistent storage is typically used for preserving data for a long period of time. Examples of persistent storage is HDD, SSD, cloud storage, and USB drives. Often, persistent storage is used for data security as it can act as a backup system in case of power failure or system crash.
The notebook persistent storage is where long-term preserved data is stored for a notebook. It is typically located in the
/storage directory. For notebooks, persistent storage is ideal for storing images, datasets, or model checkpoints for machine learning.
Even if the Notebook session is over or the kernel restarts, the Notebook’s persistent storage preserves the data, code, and outputs within the Notebook environment.
