Scenario 1: The drive is brand new and was just installed in Synology NAS.This status can occur in the following scenarios and we recommend doing the following: The system partition, DSM, and the storage pool on this drive were removed as the result of a drive/hardware failure or human error.This drive is not assigned to a storage pool.This drive contains no system partition, and DSM is not installed on it.The swap partition is mainly used as a temporary memory resource, especially when the system needs more memory resources and the RAM is full.The data partition consists of storage pools and volumes, which are mainly used for storing the user’s data and all the installed packages’ configuration.Since the system partition uses the mirroring technique (i.e., RAID 1), an identical set of system partition data will be saved on every drive in a Synology NAS. The system partition is mainly used for storing the DSM operating system, user’s settings, and system logs.Synology NAS formats drives into the following three types of partitions:
