NAS devices provide far too many benefits to be considered one of the finest, if not the best, digital storage options for personal and commercial usage. Given the high cost of these devices and the numerous brands and types available, selecting your first NAS device can be a difficult undertaking.

As a result, you'll need a thorough grasp of everything linked to network storage in order to pick the one that best meets your needs. We are happy to assist you in this matter! In the following paragraphs, I'll go over some things to think about before purchasing a new NAS equipment.


What is a NAS network storage device?


A NAS is a network storage device that can be used to store data and files on a network.

NAS stands for Network Attached Storage. It is a hard disk drive that has been connected to a network and can be accessed by other computers on the same network.

NAS devices are often used in business settings, such as in an office environment, where they can help share data across multiple computers and provide backup storage for sensitive information.

NAS Device Components:


The CPU, as a small PC, is in charge of controlling the actions you conduct on the NAS. All actions, including data backup, file sharing, data encryption, and even modification, are commands executed by the CPU, and so the performance of any NAS device is influenced by the processor type and manufacturer.

Although most of the tasks you conduct on the device will not necessitate a strong CPU, your NAS device should at the very least have a dual-core processor to handle everyday data storage and remote file management.

However, if the device is being purchased to execute sophisticated activities such as operating virtual systems or making changes to big files, the situation is different. Heavy workloads on a NAS device are conceivable, therefore it's best to choose one with a professional CPU, which implies a processor with a clock speed of at least 2 GHz and at least 4 cores to handle even the most challenging jobs.

Network port:


The network-related components of NAS devices originate from the device's connection port. The capacity to communicate over a Gigabit Ethernet connection is referred to as “GbE” by most products on the market.

Some professional versions have a 10GbE connection, which allows for substantially quicker data transfer. Multi-LAN technology is available on some devices, allowing several ports to connect the device to the network.


The more RAM a NAS has, the more it can accomplish its function, just like any other computer. True, you won't be running Photoshop or other processing-intensive apps, but having adequate RAM helps when the unit is handling many simultaneous connections, data encryption, and other chores, or running multiple applications at the same time.

Most NAS units on the market now have just 2GB of RAM, which is insufficient for secondary activities and makes the device inefficient. Fortunately, the RAM amount may be increased for improved performance; just make sure that the gadget you buy has additional ports for installing additional RAM chips.

Storage type:

Of course, storage is crucial with a NAS device because it's where all the data is saved, therefore different models allow you to connect different types of storage including HDDs, SATA SSDs, and M.2 SSDs.

While multiple types of modules may be utilized on the same device to take use of the benefits of each, such as the HDD's extended life and the SSD's quicker speed.

However, HDDs that are specifically intended for the working environment of NAS systems, such as retaining data for long periods of time without degradation and functioning constantly around the clock, are suggested. There are SSDs that are comparable to HDDs, however they will be more expensive for less capacity.

Operating System:

Because a NAS device is effectively a networked computer, it comes with its own operating system to make file management and storage management easier. This system is often accessed remotely over the Internet using a web browser on a computer; the NAS device has an IP address that is inserted into the browser, which then accesses the NAS operating system for control, much like a home network.

To make things easier, some manufacturers, such as Synology, have created an app for Android and iOS phones that allows users to access storage, browse, and share files without having to use the browser.

In general, a NAS device's services are grouped under one roof, which is the operating system, through which it is possible to manage NAS settings, partition volumes and manage their volumes, add other users to the device and grant them limited permissions, configure and monitor backup and synchronization tasks, and so on.

The most widely used network storage operating system in Synology NAS systems is DiskStation Manager. It operates on the “protected from the ground up” philosophy, which means that the system was built with the security and safety of stored data as a top concern, and the result is a system that makes managing digital data simple and easy while also protecting it from unwanted access.

Support software and tools:

A NAS device used to be just a box with a series of storage disks that could be accessed via the Internet. However, over time, these devices have evolved into strong internal hardware that allows them to run more professional programs and apps, allowing them to provide the most comprehensive data management service.

When you acquire and set up a NAS device for the first time, you'll discover that it already has a lot of software and utilities pre-installed. Each application contributes to the organization and protection of your various data while also maximizing the possibilities of your NAS device.

If these apps aren't enough, most of these devices' operating systems have an application store where you may explore and download what you need. For example, the Synology DSM system features a package center application that acts as a store to extend the device's capabilities and take use of various open source apps.

Protection and security features:

When it comes to remotely storing and accessing data, protection and security are generally the most critical considerations. NAS manufacturers recognize this and offer a variety of ways to guarantee that your data is safeguarded in the case of a failure in one of the associated storage devices or a security breach on your device, limiting access to only authorized user accounts in the operating system.

As an example, Synology is a renowned manufacturer and supplier of NAS modules. The company has a dedicated team called SIRT (Synology Security Incident Response Team) that is responsible for managing any crisis affecting the security of the DSM system, so that if a vulnerability or security issue arises, it is immediately evaluated and an update is issued that addresses the issue within one day of its discovery to keep the data on Synology NAS devices secure.

How do you choose the best NAS device for you?

NAS devices help you with everything from storing personal data for photos and multimedia to sharing office documents and files. If the amount of data to be stored and accessed remotely is less than 200 GB, it is preferable to rely on cloud services.

But someone who wants to store more than 200GB of data may want to consider buying a NAS. Synology has a huge product line, but by looking at the name of each model you will be able to know its specifications and whether it suits your type of use.

The company adopts a naming system that helps users find the NAS that best meets their needs. The first two letters in the model name represent the general shape of the device, the last two digits express the year of the model's manufacture, such as 19, meaning this model was manufactured in 2019.

How do you choose the best NAS for your needs?

Is the operating system easy to use and provides a safe environment for storing and managing data, or is it traditional and does not provide the smart solutions necessary to deal with different files?

Does it come equipped with multiple applications for arranging files and controlling device settings or does it limited to a command line, which makes it more difficult to use the device.

Synology DSM 7.0 is an operating system for network storage devices and provides everything you need to maintain the easy experience of data management.

For example, there is the Synology Drive application through which the data stored on the device can be accessed remotely through a smartphone or computer. It supports dual sync technology and works exactly like cloud storage services, it can be considered as Dropbox or Google Drive.


In general, while looking for the best NAS, you should go beyond the physical characteristics of each device. Look at the software it supports, how easy it is to handle data, and, most crucially, how secure it is. This is the device on which you will keep your data, and you must ensure that it is well protected.
