The Best NAS (Network-attached Storage) in 2021

NAS can give you great network-supported storage. This has a lot of uses, it can be helpful as a media server, encrypting and backing up files, or even as a catch-all solution for a home business.

A NAS can do great things, and there are a lot of options on the market. Some NASs are built for one specific purpose over another. While one device might be great at creating automatic backups, it might not allow access to media from any device.

If you want a NAS that is specifically suited to your needs, you’ve got to find the right one for you. Among the market, there are some clear standouts. The Best NAS can fulfill any storage and access needs you have for your files or media, and do so in a secure way.

High-quality photos, videos, 3D files, or any other demanding file formats can be a bit much. Even with external SSDs and external hard drives, storing, working on them, and sharing between multiple people gets complicated. A NAS solves all of these problems.

When you use a NAS, you can unshackle yourself from the constant dongles and cables that come with further storage. No matter searching out a cable for an old hard drive an important file is stuck on.

A NAS is effectively your own cloud storage. There are lots of advantages of this, but a big one is knowing your files will always be there, irrelevant of if Dropbox stays in business or if Google doesn’t ramp up their pricing.

With your own NAS, you also have the peace of mind of knowing everything is backed up locally. No outages or changes to user agreements are going to leave you forfeiting your data, or have your prices jacked up to maintain access.

The best home NAS can do a lot of different things. You can have instant access to files and share with others, creating automatic back-ups, store things safely, and even set-up a media server. Finding the right one can be tricky though.

These are some of the best picks on the market at the moment, for any purpose:

How to Chose a NAS

how to choose nas

Those are the best NASs on the market at the moment, with one to suit a lot of different needs. However, when purchasing a NAS you’re making quite a commitment to one device for backups and a media server for quite a while. Essentially, at this price point, you want to be sure it is going to last. This guide covers everything you need to know to make the right decision.

What You Need to Know

A NAS is quite a big purchase. This is going to be a part of your set-up for a while, so you need to know what you’re getting. If you’re a little confused by the various options or just what the specs actually mean in terms what your NAS can do, this is everything you need to know:

  • What is a NAS? – A NAS is network-attached storage. This is file storage that can work within a local network. Your files (and anything else you store) is stored within the NAS, this can be accessed by anyone given permission, and anywhere.
  • What Can a NAS Do? – You can use a NAS for a lot of different purposes. The main ones are file storage and back-up, running a media server, creating encrypted and up to date copies of any iterations of work, and even running a security network to record cameras.
  • Failure – With all of your data backed up in one bit of cloud storage, failure is a concern. This is why most of the best NASs have built-in raid configurations, this gives them great protection against any possible failure.
  • They Can Scale – As your storage needs to grow, so can your NAS. NASs can be expanded upon, and their hard drives can be replaced or switched out with those of a higher capacity.

What to Consider Before the Purchase

There are plenty of great NAS options on the market, but you need the one that specifically caters to your needs. You need to consider some things before purchase to make sure you’ve found the right NAS for you:

  • How Much Storage Do You Need? – Not everyone’s storage needs are the same. If you only need to store files and backups, you won’t need as many bays as you would if you were running a media server. Take this into consideration when buying a NAS.
  • Are You Streaming Video? – If you’re streaming video, then you might want to look into getting a NAS that is specifically designed for that, or at least one that is compatible with video streaming in high quality.
  • Do You Need Hard Drives? – The Best NASs have space for quite a few hard drives, but only some of them come with them pre-installed. Make sure you consider which hard drives are compatible and which you need to buy before deciding on a NAS to purchase.
  • Camera Licenses – If you’re using a NAS to run a camera network, you can both record the cameras and watch them live with the right software. Some NASs come with camera licenses bundled in to make it easy to set-up a small network. For more cameras, you will need to purchase more.
  • Speeds and Quality – The more RAM a NAS has, the faster it can go. However, speeds are also limited by the infrastructure for your local network. It will be much faster if you have faster local speeds. If you need your NAS to run at a particularly high speed, check that you’re getting the right NAS for this.
  • What Do You Need to Set Up a Media Server? – If you’re looking to set up a video server with a NAS, there are some extras concerns. Deepened on what program you use for this, there are some different requirements. To be on the safe side, you will want a NAS that will be able to transcode your video at their full quality, live. The majority of NASs on this list are capable of this, so it shouldn’t be a problem.
