What is NAS?

What is Network Attached Storage (NAS)?

NAS stands for “Network Attached Storage.” Network Attached Storage (NAS) is a file-based storage system connected to a network that allows multiple users and devices to store, retrieve, and share files from a centralized device. Unlike traditional direct-attached storage (DAS), which is directly connected to a computer, NAS operates as an independent unit accessible over a local area network (LAN) or even remotely over the internet. By providing a single storage hub for a network, NAS streamlines data access, backup, and management, making it especially useful for businesses and home users who need flexible, scalable, and collaborative storage solutions.

How does NAS work?

How Does Network Attached Storage Work?

NAS devices connect to a local area network (LAN) through Ethernet or Wi-Fi, allowing multiple devices to access files as if they were stored locally. Data is organized at the file level in folders and directories, simplifying navigation and sharing among users, which is ideal for collaborative environments.

NAS devices connect to a LAN via Ethernet or Wi-Fi, enabling shared local-like file access.
Network File Systems

NAS devices use different file-sharing protocols based on operating systems, such as NFS for Linux/UNIX, SMB for Windows, ensuring compatibility across platforms. NAS systems are scalable through two methods: “scale-up” by adding drives to a single NAS unit or “scale-out” by linking multiple NAS units to form one logical storage pool, boosting both capacity and performance.

NAS supports compatibility and scalable expansion across platforms.
From Basic Authentication to 2FA

NAS systems use multiple layers of authentication to keep your data secure. At the most basic level, users create unique usernames and passwords, which are stored on the NAS device. Administrators, standard users, and guests can be assigned different access levels for added control. To enhance security, UGREEN NAS solutions also support 2FA, requiring users to confirm their identity through a secondary method, such as a mobile authentication app.

NAS protects data with access controls and two-factor authentication.
