There are several ways to back up or protect your data, but if you are looking for a professional backup and restore (effective recovery is essential. Otherwise, a backup alone is not enough) with advanced technology, a NAS is a solution.
Your data is not always secure and needs to be protected, regardless of whether you are using a Personal computer, home network, or corporate network.
NAS allows small and medium-sized businesses to get all their data in one location, secure and accessible from anywhere. One of the biggest advantages of a NAS is that it is multifunctional. Can be used for personal, at-home office, and for small and medium enterprises (small and medium enterprises).
NAS has become very popular for home use to store your photos, videos, music, and documents in one central location and access them anytime, anywhere. For the professional environment, NAS has become a data storage asset.
Based on employee credentials, the company provides access to NAS devices for backup, recovery, and access to sensitive data.
According to a research report, the Network Attached Storage (NAS) market is expected to grow at a CAGR (Complex Annual Growth Rate) of around 19.5% in the period 2021-2026.
It is estimated that more than 80% of midsize businesses use NAS for multiple storage tiers with excess capacity compared to other types of storage.
The main drivers behind the demand for NAS are the increasing need for secure data storage, easy access, increasing SOHO (Small Office or Home Office), the need for centralized data management, and more.
How exactly does Network Attached Storage (NAS) work?
NAS is a system/device consisting of hardware and software connected directly to the network. It can be connected to the router using a LAN cable.
From a hardware point of view, a NAS consists of a group of hard drives in an array used for storing data, CPU (processor) and RAM (Random Access Memory) for managing file systems, launching applications, processing media files, multiple users managing, etc.
The hardware configuration determines the speed and scalability of the NAS. From a software point of view, a NAS consists of an operating system, specifically Linux, to manage the entire NAS system.
The uniqueness of NAS is that it can be accessed by many people from various locations, even through mobile devices.
NAS helps in centralizing data and optimizes storage utilization. It provides high availability of data using RAID and fault tolerance.
The data in NAS is stored in disk arrays, the data is processed using processor and RAM and the entire device is managed by the operating system. People access the data either through a mobile app or web portals.
Let’s take a look at some of the best NAS devices in the current market.

In this section, we look at brief information about free NAS software. We looked at the NAS device above, but this FREE NAS is the only software you need to install on your own server. Don’t worry if you don’t have one; you can get one cloud VM.
How to select the NAS for your network?
Every electronic device has technical indicators or parameters that must be considered before buying, and this is totally usage-based, and the same applies to NAS devices. This equation of technical parameters directly affects the price of NAS devices.
If you plan to use the NAS for personal or home use, you may prefer a lower configuration, and if you need large storage and higher protection, then move to a higher configuration.
Here are the main points to consider before choosing the best NAS.
Speed and Performance: The higher the CPU and RAM, the higher the speed and performance of the NAS. Small and medium businesses prefer higher core processors and RAM expansion for scalability reasons.
Storage capacity: NAS with 1 or 2-bay devices is sufficient for home or personal use. Small or medium businesses can choose from 3 to 5 device compartments and even an additional device compartment for future expansion.
Data Protection (Protection): This function is very important for organizations that want to protect their sensitive data. A NAS with RAID functionality would make sense for this. Even firewalls or prevention from cyber threats and malware attacks will also do.
Remote access: Easy-to-use mobile apps or web access are essential for easy backup, sharing, and restoration that can be accessed from anywhere. This function is available on all types of NAS today.
Others: You can buy a NAS with or without an HDD. If you want to select your own device, you can select a diskless device, but you will need to configure it. NAS with HDD comes pre-configured and ready to use.
Cloud integration is also another feature if you want to transfer your data to your private or public cloud.
USB port: Make sure you get a USB 3.0 port, as it is much faster than USB 2.0.
If you have personal data or an official, then protection and backup are must-haves. The backup and restore process should be a simple one and made possible with a user-friendly NAS interface.
NAS provides versatile backup and protection methods. If you are looking for personal or home use NAS then you can pick Synology 2 Bay NAS DS220, WD 4TB My Cloud, Asustor LOCKERSTOR 2, TERRAMASTER F2-210 2 and if you are looking for large storage, redundancy then you can go for Synology 4 bay NAS DS920, QNAP 4 Bay, Netgear 4-Bay ReadyNAS storage, etc.
Have you ever wondered how it is possible that every time your product owner brings in some new feature topic, the team response is they need to investigate technical possibilities and create some form of design before they can be sure how to develop that feature? Then that’s most likely because you have no Architecture Runway in place.
Google Docs does a great job of keeping things simple. The default page setup works great for most documents, and common formatting options are right on the toolbar. However, when you need to do some advanced formatting, you’ll need to dig a little deeper.
