What is a NAS and what are its advantages?

We are talking about a mechanism that runs on its own operating system, designed to centralise all data in an easy way. At the same time, it allows the distribution, viewing and backup of files by networking with different Windows, Android and iOS units. At first glance, you will notice that it is a computer. However, it does not require a screen, keyboard or mouse to perform its activities. Rather, it is made up of one or more hard drives, a processor and internal RAM that provide speed. The latter are essential to give you a satisfactory experience. Each device can be equipped with 8, 16 and 32 TB disks, depending on the user's needs and the amount of material he or she will accumulate in a few years. After all, it is up to you to decide how to use it, as it also adapts to the requirements of an office with many computers.

Professional. Using a NAS system in the office has considerable advantages for your IT administration. Business managers take advantage of its benefits so that everyone on the network, such as managers, employees and third parties, can access the same files in a simple and monitored manner.

  • Number of bays

Number of bays

It is essential to consider this aspect because the selling price is established, among other things, according to how many bedrooms the NAS has. On the other hand, a person who will use it at home demands an item with different features than a computer company needs, right? Let's look at the following.

Two. Are you aiming to get a NAS for home use? Then we recommend a device with only two hard drive bays. For example, you'll be able to back up to one, while using the other to store the rest of your photos, music or movies.

Four. When the purpose of the device is professional, it is best to buy one with this amount of space. You must take into account the price of the unit, as they are more expensive as they offer more storage capacity. On the other hand, we suggest you make an effective distribution of its functions in each slot.

Hard disk capacity

At first glance, you can see three disks with different capacities. That is, the elements that are in charge of storing your information inside the NAS. The power of these add-ons must support the data you want to put on them. Here are some common options, all functional and assertive.

8TB. If you want to store your various material in different formats, we suggest you get a NAS with two bays made up of 8T drives. They are designed for home use, as they offer more than enough space for domestic matters. So dare to take advantage of its benefits.

16TB. This alternative is made for professional computing purposes. It is an ideal recommendation for small or medium-sized businesses that require a NAS with plenty of room to store data of all kinds, or to relieve the load of the traditional servers to which they are connected.

32TB. Of all the options, this is one of the most expensive. Please keep an eye on its price when budgeting for it. On the other hand, we advise you to take one or more of these if you provide dedicated IT services to a large company or have an institution that requires a lot of network storage.

Complete. Let's say you just want a NAS computer to make your computing easier, is that it? Then go for a full-featured one that comes with two or four hard drives in addition to the case. This applies for home and professional use alike.

Partial. The hard drives are not included, only the NAS shell is sold. If you are an engineer or have a lot of knowledge in the field, this is the perfect option. Note that they are usually much cheaper than the above and give you the freedom to tailor the storage system to the desired amount.

Operating system

Basically this factor defines how comfortable it will be to work with. Again, there are designs for well-defined audiences, which makes it easy to purchase. You just have to select the right one taking into account what is most practical in the short, medium and long term. We will now show you two options.
