Direct Attached Storage (DAS) Explained

Direct Attached Storage (DAS) Explained

Direct Attached Storage (DAS) is a type of storage system that connects directly to a computer or server without relying on a network. This means the storage device is physically attached to the device it serves, offering a direct pathway for data access.

Examples of DAS include internal hard drives, external hard drives, and Solid-State Drives (SSDs) connected via cables like SATA, SAS, or USB. These devices provide high-speed data transfer rates due to the direct connection, making them suitable for applications demanding rapid data access, such as video editing or database management.

However, DAS also has limitations. Data is isolated to the specific device, hindering data sharing and management across multiple systems. Additionally, scalability can be challenging as storage needs grow, often requiring physical expansion.

While DAS remains a viable option for certain workloads, alternatives like Network Attached Storage (NAS) and Storage Area Networks (SAN) offer increased flexibility, scalability, and centralised management for more complex storage environments.
