Poor performance when data needs to be shared is a disadvantage of which storage type?

Direct attached storage (DAS) refers to a storage device that is directly connected to a computer or server, such as a hard drive installed in a server or an external drive connected via USB. One of the primary disadvantages of DAS is that it does not easily facilitate data sharing among multiple users or systems. When data is stored on a directly attached device, it typically remains isolated from other systems, making it challenging to share files or collaborate efficiently.

This limited accessibility can lead to performance bottlenecks if multiple users need to access the same data simultaneously, as they would not be able to share the storage device effectively. In contrast, storage types such as file, block, and object are designed with networking capabilities that support sharing and access by multiple users or applications, improving performance in scenarios where data collaboration is required.

Thus, poor performance due to challenges in data sharing is a key disadvantage associated with direct attached storage.
