Shopping Guide: Everything You Need to Know About Network-Attached Storage

There are a number of key factors that you should take into account when you’re looking for your new NAS server. Very different models are available out there, each one tailored to a specific type of user. This is why we’ve answered the most frequently asked questions by past users in the section below.

What exactly is a NAS?

A NAS server is a large capacity storage system that connects to your home or professional network. It allows you to conveniently access all the files and documents found on any of the devices of the network, without the need to directly connect to the unit in which they are located.

What is a NAS used for?

NAS servers have several different applications. They are most frequently used to manage files on a network, set up your own streaming server or give access to a local network to other users. You can also use your NAS to store recordings from IP video surveillance cameras.

These devices can also be configured asInternet-connected servers, allowing them to perform the same functions as online storage or hosting services. Your NAS could therefore be your mail server or store your website. As we mentioned earlier, you can also transform them into VPN servers.

What are the advantages and disadvantages of NAS servers?

Having your own NAS offers you a great series of perks. It will help make all office documents and files accessible to your employees. You can use it as a media server. It also gives you the possibility to have your own network cloud without Google being able to access your files.

Advantages Disadvantages
They allow you to have quality shared storage space. Purchasing the NAS and hard drives is a fair investment if you don’t have them.
You can access all your data, files and documents from anywhere in the world through a mobile phone application or through a specific web page.
You can create a media center to store movies, music or photos. The NAS server will send them to any device from which you can play them.
If you use it as a private cloud, you will have all your documents available on the network without Google or any other company being able to access them.
Installing and configuring a NAS is quite a simple task. Many feature their own configuration wizard to help you.

What are NAS bays?

Located in NAS servers, these spaces are where hard disks are mounted. NAS designed for domestic use generally feature one or two bays. However, you can find anywhere between four and twelve bays for professional users or business environments.

Remember that each bay will have a set storage capacity. This means that you cannot mount a 12 GB hard drive in a 10 GB bay. You also need to take into the power consumption into consideration; more bays naturally means a higher electricity bill. This is why you are not recommended to opt for a NAS server with more bays than you need.

Which RAID configuration best fits a NAS?

A RAID is a group of hard drives that has been configured to operate as one. This means that they can work by joining their storage capacities or duplicating all information, allowing you to always have your data safe in case a hard drive fails. Each type of RAID presents different characteristics that we’ve explained in the table below:

Type Features
RAID 0 All disks work as a single volume. Their total capacity is the sum of the capacities of all drives. Data is written simultaneously to the disks, improving the overall speed. The reading and writing speeds are doubled. You have no protection against failure.
RAID 1 It is one of the most commonly used. The data is duplicated to avoid potential loss. The total capacity of your NAS is half the sum of the hard drives. The writing speed doesn’t improve, unlike the reading speed that doubles. Your data is protected against possible hard drive failures.
RAID 5 The data is distributed over all disks, but the capacity of one of the drives is kept for parity. This is the most frequent type in companies and offices. One of the disks’ capacity is lost. While you gain in reading speed, the writing speed doesn’t change. Your data is protected, but you will lose all your information if two hard drives fail.
RAID 6 Data is distributed to all drives, with the capacity of two drives being reserved for parity. This type is frequently used in companies and offices. You lose the capacity of two hard drives. Reading speed is greatly improved, with the writing speed remaining unchanged. Your data is protected, and up to two disks can fail. If three disks fail, you lose all your information.

What hard drive do I need for my NAS?

While some NAS models come with built-in hard drives, it is most common that they do not. If that’s the case for yours, you’ll naturally have to buy some hard drives that offer you the right features. Their capacity is naturally a key factor, but so are their reading and writing speeds.

American brand Western Digital specializes in NAS-supported hard drives, with their network line of products being developed for this purpose only. These devices provide incredible performance. That being said, you can actually also take full advantage of any spare hard drive you might have lying around by installing it on your network-attached storage.

How should I install my NAS server?

This is actually a fairly straightforward task. First of all, you need to set up all the storage drives that you want to use. Once you’ve done this, connect your NAS to the local network. Finally, all you need to do is configure it using the NAS operating system itself.

Shopping Criteria

As you know, there are a number of critical factors that you will need to take into consideration when you’reshopping for your NAS server. In the following section, we’ve detailed these criteria to help you get it right. We’re confident that this information will guide you during your decision-making process, and that you’ll be fully satisfied with your new purchase.

Operating System of the NAS

NAS devices unfortunately don’t work with Windows. Large manufacturers have developed their own Linux-based operating systems, such as Synology DiskStation Manager, Qnap QTS, or WD My Cloud. That being said, you also have access to a series of free systems such as FreeNAS, NASlite or Openfiler.

All of these systems tend to be quite easy to use. You can even manage some of them from your smartphone – such as QNAP, Asustor or Synology. In addition, we strongly encourage you to consider the applications that each system features, to handle mail servers, FTP (file transfer protocol) and back-ups, etc.

A dual-core processor at 1 GHz should prove more than adequate if your NAS isplanned for use in a family environment. However, you shouldn’t settle for less than a quad-core processor for office use. Nowadays, mid-range products generally feature Intel Celeron processors, while professional models use Intel i3 or Xeon.

RAM Memory

Again, the amount of RAM you need will depend on the use you’ll make of your NAS server. In that sense, don’t worry too much about this criterion if you only need it to retain your data backups. For home use, 512 MB should be enough. On the other hand, you are advised to have up to 8 BG of RAM memory for your office use.

If you want to use your NAS as a multimedia center to play HD content, you’ll need at least 1 GB of RAM. Finally, a minimum of 2 GB will be necessary if you plan on frequently using your NAS as a media player in HD or 4K quality.

Maximum Storage Capacity the NAS Supports

Before you buy your own NAS server, think about the storage capacity you need and what type of hard drives you want to use with it. The simplest devices can only hold one hard drive. The most basic drives will allow you to store between 1 and 2 TB, which won’t be enough for certain tasks.

We encourage you to buy a capacity of at least 6 TB if you’ll be storing large media files on your NAS. If your device will be set up for office work, consider models with a capacity of up to 20 TB. You should also know that some NAS also allow you to install SSDs, but they cannot fully use the advantages of these storage devices.


First of all, you are advised to connect your NAS to your router with a Gigabit Ethernet connection of 1 Gbps or higher. Otherwise, its performance will probably be negatively affected. In any case, the most current NAS servers already offer 10 Gbps connectors, with many also including a second LAN jack in the box.

If your NAS features USB ports, you can expand its storage capacity or connect it directly to your printer. Micro SD card slots may also come in handy. Lastly, an HDMI output, to connect to your TV will be necessary if you want to use your NAS as a media center.

Always check the type of RAID that a NAS server supports before buying it. RAID 0 will be your go-to option if you want to make the most of its storage capacity. On the other hand, you’ll want to opt for RAID 1 if you want to be protected against potential fails and gain speed. However, remember that with this type you will scarifice half of the storage capacity.


Whenever you buy a technical product, you should choose a reputable manufacturer, who guarantees quality and good performance. In that regard, the following brands are well known: Asustor, TerraMaster, Netgear and Western Digital. These firms all offer high-quality products, and you’ll also benefit from good customer service.


Due to their many applications, both home and business, the use of NAS has increased tremendously increased in recent years. Buying one of these devices is naturally an important investment. That being said, the numerous benefits they offer willmake it money well spent.

If you want to choose the right model, it is essential that you have some basic technical knowledge and know exactly what your needs are. To do so, you should start by asking yourself how you want to use your NAS. You can then think about which configuration and manufacturer are best for you.
