Which of the following storage solutions provides fast access by connecting directly to a host?

Direct Attached Storage (DAS) is characterized by its direct connection to a host system, typically via USB, SATA, or SCSI interfaces. This configuration allows for high-speed data access because the storage device is directly communicating with the computing device without the need for network protocols or intermediary devices. This can lead to reduced latency and higher throughput compared to solutions that involve network communication.

In contrast, other storage options such as Network Attached Storage (NAS) and Storage Area Networks (SAN) involve network layers that can introduce additional latency due to the protocols used and the need for data to traverse the network. Cloud Storage, similarly, relies on internet connectivity and remote data centers, which can also introduce delays.

By connecting directly to a host, DAS stands out for its speed and efficiency, making it the preferred choice in scenarios where performance is critical and the advantages of direct access are essential.
