Which of the following is NOT a characteristic of Network-Attached Storage?

Network-Attached Storage (NAS) systems are designed to provide data storage that is accessible over a network, making them highly efficient for multiple users and applications. One of the critical characteristics of NAS is its flexibility and scale-out capability, allowing organizations to easily add more storage as needed without significant reconfiguration or downtime.

Furthermore, NAS systems are often considered less expensive compared to other storage solutions like Storage Area Networks (SANs) because they typically use standard network protocols and are built on commodity hardware. They also serve the purpose of providing on-premises data storage with many benefits similar to those of a public cloud, like easy accessibility and data sharing among users, albeit localized.

High power consumption, however, does not align with the general characteristics of NAS. Most modern NAS devices are designed to be energy-efficient, particularly in comparison to some traditional server storage solutions that might consume much more power. Therefore, characterizing NAS as having high power consumption does not accurately reflect its typical usage and design ethos.

This understanding clarifies why high power consumption stands out as an anomaly among the recognized traits of Network-Attached Storage systems.
