What Is Network-Attached Storage NAS – How Does It Work?

Network-Attached Storage (NAS) is one of the most effective ways to have backup data at hand while also having an easy way to share files between several devices. NAS can be a home or small office network-attached storage device that functions as a file server and enables its users to share data, among other things. The home NAS may behave like a centralized backup system, with all the computers on the LAN sharing backup copies of their data on it. Keep reading to learn more about network-attached storage and how it works.

What Is A Network-Attached Storage (NAS)?

Network-attached storage (NAS) is a computer device that allows users to share and store data across multiple computers over a network. The NAS free software has little processing power, and the data inside it is stored on some of the drives connected to it. User can access their NAS storage remotely by logging into the LAN or Internet, which means they would not have to go through a server when retrieving their files.

What Is Network-Attached Storage Used For?

NAS devices are becoming popular all around the world in both households and offices. They can be used for a wide range of tasks, including:

  • Storing and sharing large files, such as video libraries, digital photo collections, or large databases.
  • Giving network users access to files on remote machines.
  • Serving various networks with a backup solution (in one central location).
  • Virtualization support. With NAS servers, virtualization becomes easier and faster to implement.
  • Providing a central location for all users to access files, which includes remote locations outside the company’s network.
  • Centralizing storage. This helps ensure the user has access to the latest versions of their data and that they don’t need to worry about losing important information in case they lose their computer.

NAS Components And How They Work

Network-attached storage has several components that provide the device’s functionality. These are:


The central processing unit (CPU) does most of the work on the NAS device, acting as a server and a file storage device. This part of the NAS takes care of device operations, including throttling system resources when necessary to avoid resource hogging.

Network Interface

This is used to connect the NAS server to the network, which allows users on it to access its resources. It runs faster than the network cards that connect computers to a LAN or WAN.


This is where all the data users need to access stored, often in the form of hard drives. These are connected to the network interface to allow them to work.

This is not only a major part of the NAS device but also one that serves as a stability factor, as well as helping with security and performance issues. This part controls most activity on the NAS device, including handling server tasks and providing users access to files.

Why Is Choosing The Right NAS Important?

When choosing a NAS, you buy it to store and share data. You also want to be sure you choose the right NAS server so your data will be secure and easy to access. The right NAS server should have an ample amount of storage, as well as fast speeds when accessing the files on it.

Inadequate Storage Capacity

The most common issue when buying a NAS is inadequate storage capacity. If your device doesn’t have enough storage, you will run out of space quickly and be unable to use it effectively.

Inadequate Performance

Another problem that users commonly experience with their NAS devices is inadequate performance. This refers to the device’s inability to handle its functions properly or being quite limited in regard to data transfer speeds and general performance. If your NAS device is not up to snuff regarding performance, it will be a problem when it comes time to share files with others on the network.

Inadequate Resilience

Another issue you may encounter with a NAS device is that they are not fully resilient against certain kinds of failures. This would refer to the fact that your NAS device is less likely to be able to recover after certain types of failures occur, such as losing power or having a disk malfunction. This can be a problem if you have important data stored on the NAS device or if you need to recover files on it in case of an accident.

Inadequate Security

An issue with network-attached storage devices is that they are not especially secure against data theft and other security breaches. This can be a problem when storing sensitive or private information, such as financial information, credit card numbers, or personal information like social security numbers.

What To Consider When Choosing NAS

A lot of things need to be considered when you buy a NAS. While the value of the device is important, so is the operation and performance of it. If you choose network-attached storage with features like these, you’ll be sure it will meet all your needs.

Fast Data Transfer Speeds

The speed at which data can be transferred from the NAS server to another device is a key consideration when you buy a NAS server. This refers to the device’s ability to share or transfer files directly with another device. The secret to being able to read and write large amounts of data is using large enough files with a high enough transfer rate.


Another important thing to consider when looking at NAS devices is the capacity of the files they are able to store. This includes both their size and their transfer speed. It’s necessary for these to be large enough to store even large database files, as well as accommodate data users need access to, such as photos and videos.

An issue with NAS devices is that they tend to lack security. The data stored on them is often vulnerable to hackers and other parties. Data theft can be a major problem if you want to protect sensitive information because your security needs change over time.

The Bottom Line

Network-attached storage devices are a great way to share files, access them remotely, and back up personal and sensitive data. While they can be affordable, they are not all the same. If you want to get the most out of your NAS server, it needs to be able to accomplish everything you need with regard to flexibility and security. When choosing a NAS server, make sure you consider these things as well as its sheer value.
