Shutdown operation can help clear the cache, memory and other resources of the NAS system and applications to avoid unstable or malfunctioning applications. At the same time, shutting down the system also ensures that the NAS hardware is rested and reduces the chance of hardware failure.

Speed: Heavy use of a NAS system can cause significant network congestion and lower transfer speed. Scalability: NAS devices are not easily scalable due to the limitations of the hardware. Quotas: System admins must enforce user quotas to prevent overutilization of shared space.
