Network-attached storage, or NAS for short, is a device that allows you to store files on a network drive. There are many great uses for this technology. You can quickly share important documents or other data, but you can also use it for doing backups overnight. NAS devices have great entertainment potential if you want to watch HD movies at home with multiple devices such as TVs or tablets at the same time.

NAS drives act like cloud storage enabling you convenient access to your data wherever you are. This is why a NAS represents a very powerful solution for media playback as you can have a central entertainment station that allows you to access files faster. For example, you don’t need to use the computer when you wish to watch a movie on the TV. You might also be interested in our articles about the best wireless hard drive and the best cable modems.

It does depend on your particular needs how your ideal NAS looks like but there are a few fundamental aspects that you shouldn’t miss when shopping for such a device. These are:

1. Capacity

The capacity of your NAS plays a key role in the process of meeting your needs. Here you should aim for covering more than your present needs because you never know how large your movie collection will be in the future. The market offers you two choices here as there are diskless NAS drives and ones that already come packed with disks in various capacities. The first option allows you to customize your setup more but the last option could be more convenient for many.

2. Choosing disks

It’s important to choose NAS disks correctly because not all of them are designed to work well with a NAS. There are certain optimizations embedded into disks for NAS drives. A good example is the sturdier construction, more resistant to vibration which is particularly helpful for a NAS because these devices are supposed to be on continuously.

3. RAID

Redundant array of inexpensive disks, or RAID, represents the way your NAS is set up for providing redundancy in case one of your disks suddenly fails. The level of safety for your data can be translated into various types of RAID such as RAID 1, 5, and 6. The most common type of NAS offers at least two bays so you can have them configured as RAID 1 which is a very basic way to keep your files safe.

Choosing the right NAS can be a challenge and there are many features to consider. This little guide only gives you a rough idea. It’s now time to take a closer look at what the market has to offer. Various NAS drives have been assembled here based on their overall cost-effectiveness. Factors such as performance, ease-of-use, and security have all been taken into account and the result is the following list of individually reviewed products.
