Network Attached Storage (NAS)

Where do you store the company data and how do you backup?

Today, there is a great amount of cyber-attack threats all over the world. It is necessary to have a system that lets employees share their data with co-workers and secure an original copy of the data by backing it up. Over the last 20 years, most small businesses used Windows Server to manage their domain, share data within the company, perform backups, and so on. This method was great for them since a single server provides multiple services, however a Windows Server is expensive and complicated. An alternative is Network Attached Storage, also known as NAS, whose main role is storage and backup.


What is Network Attached Storage?

A NAS system is a storage device connected to a network that allows storage and retrieval of data from a centralized location for authorized network users and heterogeneous clients. NAS systems are flexible and scale-out, meaning that as you need additional storage, you can add on to what you have. NAS is like having a private cloud in the office. It’s faster, less expensive and provides all the benefits of a public cloud on site, giving you complete control.


How does Network Attached Storage work?

NAS works like a computer. It has a CPU, storage, networking, and an operating system. This system is divided into three parts, storage, management, and networking. The NAS box works like a brain. It makes sure the data is getting saved on the hard drives without problems and restricts access to users based on the permission settings. Specialized hard disks built for the system are attached to the box. The NAS box is connected to the company network and clients can now access the storage based on their permissions.

What are the benefits of using Network Attached Storage?

Easy to install and configure

Most NAS devices from reputable manufacturers come with their own storage management software that makes it easy to set up and configure your NAS device for use on your network. For example, many Synology NAS devices come with Diskstation Manager, a user-friendly web-based operating system that has a number of easy to configure features, including seamless file sharing integration with Windows and Macs, Automated Data Backup, multimedia solutions for media access and streaming across the network, in addition to network security features that are perfect for Startups and Small Businesses that have a minimal level of Network Security in place.



Most NAS devices use CPUs from ARM, MIPS and Atom, so they use a lot less electricity than the server. If you need more storage space, you can simply purchase another hard disk drive and attach it to the docking station. It is much more cost-efficient than cloud storage services. The electricity bill is pretty much everything you need to pay for maintenance.


No need to carry a storage device

NAS devices can be accessed over the Internet, so you do not need to carry a storage device like a USB and external hard drive. All you need is a connection to the Internet.


Highly secure

Most NAS devices include a number of built-in Network Security features that will help to protect your data.

Examples of common built-in security features include 256-bit data encryption for avoiding unauthorized access, 2FA (or two-factor authentication) as an additional layer of access security and policies for password strength and user access permissions.  Some devices even have built-in virus scan and prevention features.

Popular NAS vendors



Synology provides Centralize data storage and backup, streamline file collaboration, optimize video management, and secure network deployment to facilitate data management. Products from this vendor are pricy, but it has a great user interface for NAS.


Western Digital

Western Digital designs, manufactures and sells data technology products, including storage devices, data center systems and cloud storage services. WD is an excellent way to obtain an inexpensive NAS system. Most NAS devices are diskless, but WD comes with a disk.



Netgear produces networking hardware for consumers, businesses, and service providers. Netgear NAS can stream HD on multiple devices and you can fully control it through the NETGEAR Insight app. This device stored data with RAID configuration and has a disaster recovery option to safely store your business documents and media.
