What characterizes the direct attached storage environment?

Direct attached storage (DAS) is defined by its direct connection to a single server or computer, typically through interfaces such as USB, SATA, or SCSI. This configuration allows for high-speed data access since the storage media is directly linked to the computing resource, resulting in minimal latency compared to networked storage solutions. In this environment, the storage is dedicated to the server it is connected to, which is an important characteristic that differentiates it from other storage types like network-attached storage (NAS) or storage area networks (SAN), where storage is shared among multiple servers.

While shared storage environments are useful in contexts where multiple servers need to access the same data, direct attached storage is specifically designed for use with singular systems, often leading to simpler setups and potentially lower costs. The other options presented do not accurately represent the characteristics of direct attached storage.
