NAS systems – Network Attached Storage


NAS, or Network Attached Storage , is a file level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients.  It is often manufactured as a computer appliance – a dedicated standalone device with integrated components designed specifically for storing and serving files. 

The Following are characteristics of the NAS system:

A dedicated file storage server connected to the network.

An easy to use interface for managing users and permissions.

Scalable storage capacity.

NAS systems are composed of an embedded operating system on commodity hardware that provides file-based data storage services to authorized client computers on a computer network. Accessed over standard Ethernet or Wi-Fi connections, files can be transferred between any client desktop, laptop, or mobile device independent of its underlying operating system. The primary goal of NAS systems is to make it easier for users to share and manage their files without resorting to complex IT procedures. Another important goal is to improve the scalability and performance of file sharing by using lower-cost hardware platforms than would otherwise be necessary.

How Does a NAS System Work? 

A NAS system consists of one or more hard drives that are connected to a network. The hard drives are typically configured in a RAID array, which provides redundancy in case of failure. A NAS system also has an operating system that is optimized for file sharing. The most common operating system for NAS systems is Free NAS. 

Benefits of NAS 

There are several benefits that come with using a NAS device. First, NAS devices offer expandable storage. This means that you can start with a small amount of storage and then add more drives as needed. Second, NAS devices offer redundancy. This means that if one drive fails, your data will still be safe because it will be stored on the other drives in the system. Third, NAS devices offer easy file sharing. This means that you can quickly and easily share files with other users on the network without having to go through a complex file sharing setup process. Finally, NAS devices offer good performance. This means that you will be able to access your files quickly and easily without experiencing any lag time.

There are many benefits of using a NAS system, including: 

* Cost – NAS systems are typically much cheaper than SANs. This is because you don’t need to purchase any special hardware or software. 

* Flexibility – NAS systems offer more flexibility than SANs. For example, you can easily add or remove drives from a NAS system without affecting the rest of the network

* Ease of Use – NAS systems are easy to set up and use. Free NAS, in particular, offers a web-based interface that makes it easy to manage your files and shares. 

* Scalability – NAS systems are very scalable. You can start with just one drive and add more as your needs grow. 

* Performance – NAS systems offer good performance for small to medium sized businesses.  

Types of NAS Systems 

There are three main types of NAS systems available on the market: single-drive systems, multi-drive systems, and SAN systems. Single-drive systems are the most basic type of NAS system and they typically only support one hard drive or SSD. Multi-drive systems support two or more drives, and they offer redundancy and increased storage capacity. SAN systems are the most complex type of NAS system and they use a storage area network (SAN) to connect multiple NAS devices together. SAN systems offer high performance and scalability but they can be very expensive.


When it comes time to purchase your own personal or business NAS system, there are many things you’ll need to consider before making your final decision such as capacity, price, scalability, ease of use, and more. However, by keeping the above information in mind, you should be well on your way to finding the perfect device for your needs.
