Blocks are typically read more quickly than files on a storage device and are typically better suited to high-performance applications. NAS is not typically as fast as storage area networks because SANs are block-based storage. NAS is dependent on the local area network to which it’s connected. Employees access files from the NAS like they do any other file on the network. NAS devices may provide other features, too, like integrations with backup software or creative tools. The device contains a number of replaceable drives-either solid state drives or hard drives-as well as a processor and often a built-in operating system. It typically uses Network File System (NFS) or Common Internet File System (CIFS) protocols, although other choices like HTTP are available. NAS is a file-level data storage device attached to a TCP/IP network, usually Ethernet. While NAS and SAN technologies both allow teams to share data remotely over a network, they’re set up differently and vary in transfer speed. Deployment often requires making physical changes to the data center.Requires more administration time than NAS devices.Offers a simplified management interface.Also have security features, which cost more money to implement and maintain.Generally less expensive to purchase and maintain.Network architecture enables admins to scale performance and capacity.Scalability is a major driver for purchasing a SAN.High-end NAS systems scale to petabytes.Entry-level and NAS devices aren’t highly scalable.Technologies like Fibre Channel and NVMe help process traffic requests.Typically higher-performing in environments like high transaction databases and e-commerce websites.Higher processing capabilities necessary for performing bandwidth-intensive tasks.High-speed networks that can make up for performance losses within NAS.Network formed by mapping layers to other protocols like Fibre Channel Protocol (FCP).Uses SCSI protocol to communicate with servers.Accesses specialized SAN file system servers share data by providing file-level access to servers on the same Logical Unit Number.May operate within a global namespace, aggregating multiple NAS file systems to present a consolidated view.TCP/IP networks, most commonly Ethernet.The following table highlights some of the key differences between NAS and SAN environments. Bottom Line: NAS and SAN Aren’t Opposites.This guide defines NAS and SAN, identifies their differences, and presents use cases for both architectures. They’re beneficial for exchanging files and data among remote teams, which is essential for most businesses. Both NAS and SAN provide a fast, cost-effective way for organizations to support large volumes of stored data, but they approach this differently and are often suited to different applications. Network-attached storage (NAS) and storage area networks (SAN) are two methods of configuring storage devices over a network to help business users share data wherever they’re connected to the network.
