A customer requires a solution for external storage to efficiently share files between systems. What type of storage should they use?

The most suitable solution for efficiently sharing files between systems in this scenario is Network Attached Storage (NAS). NAS is designed to allow multiple users and devices to access files over a network, making it ideal for environments where collaboration and file sharing are essential. It provides a centralized location for data that users can access using standard networking protocols, enabling seamless file sharing without the need for users to directly connect their systems to storage devices.

NAS systems often come with user-friendly interfaces, making it simpler for customers to manage permissions and access rights, thus enhancing the efficiency of file sharing among multiple users. The scalability of NAS solutions also allows customers to expand their storage needs as their data grows, maintaining their collaborative capabilities over time.

In contrast, Direct Attached Storage (DAS) connects storage devices directly to a single computer or server, which would limit file sharing capabilities since it does not provide network access to multiple systems. Software-Defined Storage (SDS) focuses on abstracting storage resources and can be complex to implement without a specific need. Storage Area Networks (SAN) are typically used for block-level storage and are more suited for environments requiring high performance and availability, such as databases, rather than straightforward file sharing. Thus, for simple and efficient file sharing across systems, NAS
