These are the best NAS (Network Connected Storage) of 2019

What is a NAS and what is it for?

NAS have a similar performance to cloud storage systems: allow you to access all your files from any device that is part of the network. This means that this technology shares the storage of a computer with other personal computers.

You can use them to store music, videos, documents, photos or any other type of file.

One of the most popular uses of NAS is video playback, since you can view them from your TV without having to connect your computer to it.

A NAS disk is designed to be on permanently, so you can access your photos, music, videos, etc. whenever you need it. Most have timers that you can program to turn off or on the hours of the day you want.

Below we talk about some of the features that we consider should be taken into account before buying a NAS.

What capacity does a NAS need?

It is obvious that if you are going to use the NAS to store files, the capacity that this has to be one of the main elements to take into account.

Some NAS come without any type of hard drive, the advantage of which is that you can choose the same capacity you need.

You can find discs of up to 10 TB (although you will have to pay at least 400). If you do not need this high amount of space, you can opt for 4 TB discs, which is also a lot of space, but it will cost you much less money.

NAS drives

When you go to choose disks for your NAS, you have to notice that they have been designed to work inside a NAS box.

If the disk has been designed for this purpose, it will have a greater resistance to vibration, something quite necessary since as we have said before the NAS is almost always on (which produces continuous vibration).

Disks designed for NAS usually also have a utility known as intelligent error recovery, which prevents, in the event of an extensive error recovery, disconnecting from RAID (below we explain what RAID is).

They also normally have a command termination system, that is, if the connection is interrupted for a particular reason, the disk designed for NAS is programmed to minimize data loss thanks to the termination of the command in process before disconnection. .

What is RAID?

The acronym RAID means in English redundant array of independent disks, that is, redundant array of independent disks. You still don't understand, right?

In a simplified way, we can say that RAID is a data storage system between different devices such as hard drives, SSD, etc. among which the exchange or replication of data is possible.

Initially, the RAIDs began to be used to unite in a single network devices of worse performance (usually older or of low cost), and in this way, achieve through that union much more power and better performance.

Today, RAIDs are used for many other purposes, including the ability to connect different devices, higher performance, more speed, efficiency, protection against possible errors or failures, etc.

One of its most popular uses is undoubtedly the security that RAIDs provide, since if a disk fails, all your data will remain secure.

Most NAS come with at least two slots, which means you can use one of them to install a RAID. In this way, hard disk 2 will be a reflection of the first one, and if either fails, all your data will be protected.

Hot swap: hot swap

Function hot swap It means that you can take out or insert a hard disk without having to shut down the NAS first, something that can be very useful if you don't want to interrupt any activity that the NAS is carrying out.

Remote connectivity

It is important that you consider whether you will need remote access to the NAS. Previously it was necessary to be subscribed to services offered by third parties, but currently, when you buy a NAS you can also create an account with the same company that will configure the NAS that offers you the remote connectivity service.

In this way, you will only have to enter your account, and the company will make it possible to connect to your NAS.

Best NAS of 2019

Synology DS218j

An excellent performance, a software Incredible, and an easy-to-use user-friendly, NAS model of Synology DS218j It is a very good purchase option.

Synology DiskStation DS418j

This product implies that Synology intends to repeat the success of the model DS416j without having to imitate other products of the same range.

For almost the same price, the DS418j offers higher CPU performance and more USB 3.0 ports. It is a very good NAS for those who want to do more than share files between devices, and use the more than 80 applications compatible with the DS418j.

Technical specifications:

  • Two NAS drive
  • Realtek RTD12931 dual-core 1.4GHz CPU
  • 1GB DDR4 (not socketed)
  • 1x Gigabit Ethernet

The QNAP is undoubtedly one of the most impressive NAS. Being able to provide all the sufficient energy to practically all the tasks you wish to perform.

Its range of applications is very complete and the interface is excellent. One of its disadvantages is that it lacks MKV compatibility with its original application, which means that you will have to pay for Plex to play files on mobile devices.

Another small mistake that we have found is that the device is somewhat louder than expected, and although it has a good value for money, this NAS is not cheap.

If you have no budget limit and are willing to pay its high price, we can assure you that the QNAP TS 251A It is a good purchase option.

Technical Specifications:

  • Intel Celeron N3060 dual-core 1.6GHz (up to 2.48GHz)

  • Maximum capacity: 2x 8TB 3.5in SATA 3 disks
  • Size: 102 x 169 x 219 mm

Synology DiskStation DS218

The great iron of DS218 is that if we analyze it individually we find an excellent NAS, but if we put it next to the DS218Play or DS218 + models, it is left behind.

Now that the QNAP brand offers dual-LAN for less money, and the possibility of increasing RAM capacity, the DS218 should be less expensive or at least, if it maintains its high price, improve it to make it worthy competitor.

We still think that the DS218 is still a good NAS option, but it fails to overshadow the DS218Play model.

AS1004T asuster

What we like about AS1004T asuster It is its ease of installation, its relatively quiet operation and its decent performance.

However, this NAS is not fast enough for transcoding of hardware, so you need good native support for all your files.

A point in favor of the Asustor AS1004T is its design with four compartments (when most NAS offers only two). So if your priority is storage, before performance, this is a good option.

Keep in mind that its interface is not as acceptable as that of some competing models.

Technical Specifications:

  • Marvell ARMADA-385 1GHz (Dual-Core) processor
  • Capacity: 512MB
  • 1x Gigabit Ethernet
  • 1x USB 3.0 rear port, 1 x USB 3.0 front port
  • Ventilation system: 1x 120 mm
  • Maximum capacity: 4x 10TB
  • Size: 65 x 164 x 218 mm

Synology DiskStation DS119j

A NAS suitable for all types of users may be the best purchase option if it is the first NAS you will use. This Sunology option allows you to have a NAS that offers a fairly acceptable value for money.

You will not have to spend much (especially if you compare the price with that of other devices), although you will not receive any extra privileges either. You get a very basic product, but useful if you don't ask for much (and if you don't want to spend a lot).

WD My Cloud Mirror 4TB

It is difficult to find a NAS that is easier to use than the WD My Cloud Mirror 4TB. Its initial configuration is very simple and even the configuration of remote access.

It works great for sharing music, movies, photos and documents, and its performance is more than acceptable. As an inconvenience we can highlight that it does not have a wide variety of applications available.

However, if you are a novice user, and your priority is ease of use, it is worth taking a look at this model with 4 TB of storage included. An excellent value for money.

Technical Specifications:

  • Marvell ARMADA-385 1.33GHz (Dual-Core) Processor
  • 512MB
  • 1x Gigabit Ethernet
  • 1x rear USB 3.0 port

WD My Cloud Home

The design and style of hardware My Cloud Home is excellent. However, their software It has some lacks.

My Cloud Home can provide DLNA storage to access from a smart TV or a personal cloud storage service. However, if you are a very demanding user, we recommend Synology, QNAP models or high-end My Cloud products.

My Cloud Home is like having your own cloud server that only you can control. You can save in it all the files you want, in addition to sharing them and have access to them from different sites.

This NAS is exactly that: a way to synchronize your files in a cloud of your own.

Technical Specifications:

  • Interfaces: Gigabit Ethernet, Power Supply (DC in), USB 3.0 port
  • Size: 175.5 x 140 x 53 mm
