Understanding Direct-Attached Storage (DAS) Direct-Attached Storage (DAS) is a digital storage solution directly connected to a computer or server without a network interface in between. Unlike network-attached storage (NAS) or storage area networks (SAN), DAS is dedicated to a single device, offering high-speed access and simplicity. It's ideal for users needing fast, local storage for applications like video editing or gaming. However, its scalability and sharing capabilities are limited compared to other storage options. DAS is a practical choice for straightforward storage needs where performance and direct access are priorities. read more here: https://www.lenovo.com/jp/ja/c/servers-storage/storage/das/
