Direct Attached Storage
Direct Attached Storage (DAS) is a storage architecture where storage devices, such as hard drives or SSDs, are directly connected to a single server or computer via interfaces like SATA, SAS, or USB, without using a network. It provides dedicated, high-speed access to storage for that specific host, making it simple to deploy and manage. DAS is commonly used in scenarios where low latency and high performance are critical, such as in local databases or media editing workstations.
Developers should learn about DAS when working on applications that require fast, reliable storage access without network overhead, such as high-performance computing, video rendering, or local server setups. It's particularly useful in environments where data does not need to be shared across multiple systems, as it offers cost-effective and straightforward storage solutions compared to networked alternatives. Understanding DAS helps in optimizing storage performance and making informed decisions about infrastructure design.
