What is the primary difference between NAS and DAS?

The primary distinction between NAS (Network-Attached Storage) and DAS (Direct-Attached Storage) lies in how the storage is accessed and connected within a network.

DAS is directly connected to a single computer, making it local and primarily used by that one device. It operates without a network layer, meaning that the storage is not available to other machines over a network. This localized access is why stating that DAS does not connect to networked storage devices is accurate. It emphasizes that DAS is intended for single-user access rather than multi-user environments.

On the other hand, NAS is specifically designed for sharing storage across multiple devices over a network. It connects directly to the network and is accessed by various users and devices, which enhances collaboration and accessibility.

This fundamental difference in connectivity and intended use is crucial in understanding the functions of storage solutions in different environments.
