NAS is a Network Attached Storage - essentially, a hard drive connected to a network, making it accessible to users over that network. It’s basically a high-capacity hard drive connected to your network, ready to share files anytime, anywhere within it.
Most NAS storage devices are purpose-built enclosures designed to hold one or more hard drives, often featuring multiple bays for added storage capacity. They come equipped with dedicated software and a built-in network interface card, allowing them to connect directly to your home or office network without the need for a dedicated computer.
In practical terms, a NAS is a self-contained box that sits on your network and provides a shared pool of storage. This space can be used to store, back up, and share files, and it is accessible to authorized users over the network in exactly the same way as if it were one of your computer’s internal hard drives. Such systems often support additional features, such as user access control, RAID configurations for redundancy, and remote access, making them a versatile solution for both personal and business data management.
Whether a NAS will remain a simple data storage device or evolve into something far more powerful depends on your IT expertise, the time and money you’re willing to invest, and your ambition to turn it into more than just a storage box.
A NAS isn’t just a place to keep your files - it’s a versatile tool that can transform the way you manage data at home or in your business. Beyond basic storage, a NAS can:
With the right setup and know-how, your NAS can become the central hub of your digital life, offering far more than just storage.
Now the network-attached storage (NAS) comes with the solution. NAS is more than typical server or workstation, it is a file-level storage based on a specialized frame, that is connected with other computers through a local network (or sometimes, via the Internet).
For most users, a network-attached storage is a simple, relatively cheap version of a file server or a network backup drive that needs a little maintenance and can easily be stored at home, in a small office and, generally, anywhere you pleased.
With the NAS on hands, a user can store the significant amount of data, easily access to any of these data through wired connection or Wi-Fi, back up their without so much problems, organize torrent or peering share for some files, and much, much more.
Now let’s look deeper, what this wonderful NAS is.
A key to the nature of network-attached storage is the dedication to the tasks of file-storing and backup. NAS servers for storing your data, not for processing it. Although it is technically possible to run some server software on a NAS, it is not fit for this task.
A typical NAS comes with a simple, somewhat slow processor unit, a stripped-down version of a server OS, and a lot of hard disk space organized in virtual (logical) drives. Main storage units on a NAS are standard hard disks, much like in the common servers.
To run an exchange of data, network-attached storage units support common file-transfer protocols such as SMB, NFS, and other. Often, a NAS provides to user more than one protocol.
To further improve user experience, some NAS devies include advanced functions of file storage and exchange, such as FTP clients, torrent software, some dedicated, reliable tools for backing up and restoring user files, and much more.
According to Wikipedia, network-attached storage devices can be divided into three types by hardware used:

Comparing network-attached storages with more traditional file servers (which provide the same service for most users) and DAS (direct-attached storages), we can mark up a bunch of pros and cons, which have to contribute for the end user’s choice:
The administration of a NAS often works through a Web, just like any other Web form, and the NAS do not require a monitor or any input device at all.
The benefits of simplicity are also in... simplicity, too. Less technical complexity leads to less technical problems. Groovy!
For all these merits we can add another which can be very important for many, many users: the network-attached storage systems are cute! These little stylish boxes by external designs have a no point one with older, bigger, uglier blade-factor or 19” rack-mounting servers.
And now we must repeat considerations that can speak against a NAS.
To learn how to best mitigate these drawbacks, refer to the Efficient NAS Backup Strategy Guide.
This is the simplest of the questions discussed: you can go to your local hardware mart, or open an Internet shop page, read carefully specifications for different NAS systems, and choose the one that fits perfectly (or as much as it is possible in our world, anyway) your needs.
The key feature of NAS device is the maximum data capacity it can maintain. More disks means more space for your data, but the price tag and the power consumption are climbing up too. Be careful and not surrender to any greedy impulse for purchasing extra terabytes you don’t need!
We recommend you to use only hard drives specially dedicated for NAS or server purposes in your NAS unit. Your NAS hard drives will work in 24/7 mode, which can be too demanding for the most of the standard hard disks.
You may want your network-attached storage device to have not only wired Ethernet connection, but also a Wi-Fi unit. In this case, look on specifications and see if the models you want to choose have built-in WiFi capacity.
Think if you really need special software out of the box, such as a BitTorrent client or an internal NAS backup solution in your NAS. Many manufacturers provide solutions with all these functions.
Choosing the best NAS for your goals, you may simply read some reviews or specialized articles, just to take all the consideration into account and take the right decision about your next NAS.

A long time ago before the coming of NAS storages we were depended completely on powerful data servers and their dedicated priests, system administrators. But now we are no longer living in dirty caves, we do not wear hides.
Tools comes to be much less ugly and a bit more specialized than a stone axe, a club, or a roaring jack-of-all-trade server in the big ivory eATX case. This is what the mankind calls a progress.
So it is a true with network-attached storages, the perfect, small and relatively undemanding type of data-storing devices. Use the NAS rationally and wisely, share, backup and preserve your data with these tools, and you will be on a wave of the technical progress - just for now!
Operational quality | Standard server | NAS |
Price | High | Relatively low |
Maintenance cost | High | Low |
Supporting | Demanding | Very simple |
Data processing functions | Usually a huge amount of | None or little |
File-sharing protocols | Usually only one | Usually many |
Storage capacity | Expandable to big size | Just to fit any requirements |
Storage security | Relatively low due to attacks | Relatively high |
