Are you looking for a NAS and do not know which one to choose? Here we list the best Network Attached Storage you can buy right now.

Do not worry! We have done the work for you!

Why do you need a NAS?

What happens today is that we all have many videos, photos, movies, and files and our smartphones and computers are quickly filled up. This makes our computers go slower and we are forced to make copies on external hard drives. In the end, everything ends up being a mess because when we do not have the discs at hand, we can not access our information.

All this problem is solved with a NAS (Network-attached storage). This external memory device allows you to store information in it and recover it whenever you want only with an Internet connection. In addition, you can access it from all kinds of devices and you can configure it so that others can also access it. For example, you can give access to your wife, your children or people in your office.

Now let’s explain what you have to know before buying a NAS

What you can get with a NAS

If you decide that a NAS is a good purchase, the first thing you have to know is what are you going to use it for. For example, you do not need a high-performance NAS if your idea is to share Office files or back up your laptops. On the other hand, if you will need a good NAS if you want to watch HD videos simultaneously on several computers and your smart TV. In such a case your NAS should have a good processor, high memory and offer high data transmission speed. So following are the important factors to look for when buying a NAS.


The basic idea you should consider while choosing a NAS is whether you will need more modules because the high-end equipment allows adding more hard drives (usually between two and eight) and the basic equipment usually comes with a single hard drive.

To give you an idea of your needs we give you four examples:

• You only need 1 or 2TB if you want is to make backups of a couple of computers and your family’s mobiles.

• You need a minimum of 6TB if you’re a movie buff and you like to have your movie collection always available.

• You need between 10 and 20TB if you want the equipment for a small office or a small workgroup.


The most basic equipment costs around 185 USD and the most expensive equipment is worth thousands of dollars. The difference lies in the processors, data transmission speeds, RAM, the number of slots to place hard drives and the amount and capacity of hard drives that come included.

You should be careful when comparing because several computers are sold without including the hard drives and offer space to place only one. These models are worth less than 130 USD. On the other hand, the office equipment has several slots, they allow you to include hard disks with a lot of capacity and offer high performance. But these will easily rise above 1300 USD (also this price does not include hard drives).

With discs or without discs?

You have the option to buy a model that includes pre-installed discs or buy it without discs and choose the ones you want to use.

For users who do not want to complicate life, the most practical thing is to buy a NAS with pre-installed discs. In this way, incompatibilities and configuration problems are avoided. The disadvantage of this option is that the equipment is more expensive and that you lose possibilities to adjust the benefits to your needs.

Something very important to consider is security because models with more than one slot offer methods to save copies on more than one disk and this reduces the risk of information loss.


The most normal thing is that the equipment does not have WiFi to transmit and receive information thanks to its direct connection to the router via ethernet cable. If you want to have good performance, we recommend that you do not use the free router offered by the telephone company and that you have a quality router. Check out our list of best wireless routers to know more.


Like a PC, a NAS also has CPU, RAM and operating system (usually Linux or Unix). A NAS with 512MB of RAM and a Dual-Core processor begins to be appropriate for domestic use and a NAS with at least 2GB of RAM and a Quad-Core processor is a minimum necessity for small offices. If you want to watch 4K movies on several devices at the same time or perform complex tasks, we recommend that you choose good processors and high memory. But surely the equipment hangs up or will give you some kind of problems.

Software and setup

All NAS come with some operating system. What happens is that your system is much more limited than the typical Windows or Mac that you are used to seeing. The operating system of a basic NAS only allows to save files and transfer them, and create users and give them the access to it. If you buy a high-end NAS the possibilities skyrocket.

The configuration is usually easy. Many computers come with installation CD and others come with instructions that help in the setup through the web portal. The software allows users to create and manage file permissions. For example, you can let your children only access the children’s movie folder.

Remote access and personal cloud

The manufacturers of the equipment offer web portals that allow you to connect to your NAS remotely having only an internet connection. This is very convenient because it allows you to access your folders from anywhere using your mobile, tablet or computer.

The good thing about this option is that your files are always on your NAS and not on a remote cloud server that belongs to another person or company. This way you always know that you have total control of your files. At the same time, you do not have to pay any monthly fee either because the NAS is yours and the manufacturers of NAS equipment offer the cloud portals for free.

There are several models that allow you to work with third-party Apps such as Transmission (Bit Torrent client) and PLEX (a media server). This allows you to configure your NAS to download and save movies and play them automatically on your smart TV. There are also computers that are compatible with Android and iTunes.

File security

Many of the NAS in the market allow encrypting files and creating extra security barriers. You can limit access to folders and easily manage group permissions.

Now we go to perform a detailed analysis of each selected model. It is important to keep in mind that there are many models and that it is complicated to select a favorite one. The main idea is that the buyer’s choice fits their needs. Our ten choices comprise a wide variety of features and range from very simple NAS to complex models that support multiple hard drives.

Network Attached Storage – The Best List

#1 QNAP TS-231P – The Best NAS for Home and Small Office

12 Best NAS Devices 2021- Buying Guide and Reviews 13

This model has just hit the market and offers incredible value for money. It is still not very well known but in our opinion, it will be the new best seller of coming years.

It stands out for its 1.7 GHz dual-core processor, its 1GB RAM, its three USB 3.0 ports and its two LAN ports. Its hardware is more than enough for domestic and small office uses and allows multitasking operations with excellent performance. Its reading speed is 224 MB / s and its writing speed is 176MB / s (much higher than its competitors).

During our tests the performance of the device was unbeatable. It stood out for its capacity of streaming and its performance when we attach a USB Wi-Fi. We were able to watch movies in 4k simultaneously on three computers while doing file writing tasks.

Another thing that we really like is the Hybrid Backup Sync that allows the connection with external cloud services (Amazon Glacier, Azure Storage, Google Cloud Storage, Google Drive, Microsoft OneDrive and Dropbox®) to guarantee the recovery in case of disasters.

#2 WD My Cloud EX2 Ultra

12 Best NAS Devices 2021- Buying Guide and Reviews 14

On this occasion, we have decided to propose for the first time a model that also includes discs. For this model, we recommend the configuration of 8TB because it is very versatile and will be enough to give it a domestic use. The disks chosen are WD Red for NAS and are designed to operate in environments that operate 24 hours a day, 7 days a week.

The Cloud EX2 Ultra has a 1.3GHz Dual-Core processor and 1GB of RAM. The equipment is ideal for homes or small offices and has a correct performance until we begin to demand it. For example, it works well to transmit movies in 4k with a device, but when we start asking you to broadcast on more devices the problems arise. The same happens if we open several applications simultaneously that require memory.

Its configuration is intuitive like all other equipment in the list and its functions are standard. It should be noted that it offers a specific video surveillance software that has a very fast setup.


Different programs for backups and remote copies in Amazon S3 or ElephantDrive.

Specific software for video surveillance

2 USB 3.0 ports

1 Gigabit connection at 1000Mbps

#3 Synology DiskStation DS115j


12 Best NAS Devices 2021- Buying Guide and Reviews 15

This NAS is the most basic of the list and we have decided to include it for its stability and price. It is not a suitable model for applications that require a good processor and memory but serves to perform basic functions.

The DS115j comes with a 0.8 GHz processor and 256MB RAM. The computer works well to back up 3 to 5 devices and is a good solution for saving files. Its deficiencies begin to be seen when it is used for multimedia, for example, the processor gives problems if you want to watch movies at high resolution.

Something we like about it is that it can be adapted very easily as a home surveillance center. All that is needed is to buy IP cameras because this NAS already comes with a package for surveillance and two licenses of free IP cameras. We have tested the surveillance function and it allows you to control your home from your mobile and save the recordings automatically.Its configuration is fast as in all Synology and it has the DSM operating system and the packet center.

The equipment comes without hard drives and only incorporates a 120GB HDD internal hard drive. The maximum memory capacity that can be placed on this model is 20TB (10 TB x 2 hard drive).

The DS216J is ideal for home environments as long as we do not request 4k movie playback simultaneously on multiple computers. After testing, we can say that its ideal use is for a standard family that wants to save files and makes copies of their phones and PCs.


Good value for money

Adjustable LED indicators

Intuitive operation

Automatic backups for Mac or Windows

Easy file exchange with any operating system

Good compatibility with SmartTV, mobile, and other devices

12 Best NAS Devices 2021- Buying Guide and Reviews 22

The big difference between both models (DS216+ II) is that the DS216play does not incorporate the encryption extras, it does not have antivirus AppArmor, it does not offer private cloud without connection and its operating system has fewer extras for the office.

The DS216play works with a 1.5 GHz processor and 1 GB of RAM and allows read speeds of 107 MB / s and write speeds of 91 MB / s.

12 Best NAS Devices 2021- Buying Guide and Reviews 23

This is the new version of TS-231 that we talked about earlier. The truth is that QNAP does not stop innovating and the new model has left us very happy.

Input, the new model comes with remote control and includes SD slot. Its processor improves a lot and the performance is incomparable. However, the price shoots to more than 738 USD.


• High speed

• Remote control

• 4k excellent and codifies although this disconnected

• Possibility of creating Karaoke system


• High price

• It lacks a bit to reach the benefits of equipment that are above 1230 USD.

Its features and ease of use make it one of the best proposals on the list.
