Buying Guide:

5 Bay NAS Buying Guide

We promised to explain the term 5 Bay at the beginning of this article, and so here we are! To buy a NAS device that meets your needs, you need to figure out how many bays do you want?

Technically, bay refers to a fundamental component of NAS that determines the maximum potential storage capacity of the device. Although the number of drives that it can carry also has a significant impact, the count of bays remains the most influential aspect of all.

By standard, you will need a NAS device featuring around two bays if you work from home or occasionally need this device. For professional, office use, you will need a 4 to 5 bay storage device.

And that makes it quite evident and clear. This particular guide is exclusively for professionals who need a storage solution quite frequently. With that said, let’s explore the true potential of the 5-Bay NAS device.

Advantages of Using 5-Bay NAS

You’re looking for a NAS device to ease out your storage problems. So, that counts for the basic advantage for which you seek a good model of this innovative technology.

But apart from storing data and making it available remotely, what else can you expect from a NAS device? Are there other ways through which it can cut down your worries?

Of course! Like all other devices, NAS devices also come with several secondary, or more accurately, associated perks. Amongst these, the most admirable one is the maximum possible security that it provides.

By centralizing the file storage, NAS devices maximize the security and reduce any chances of corrupting or losing data. You can further secure the stored data by setting up accessibility permission. Allow only a few trusted authorities to access the files. More importantly, it cuts down your hardware expenditures!

If you have a NAS storage device set up for your office, you don’t need to invest in costly PCs with better hardware and storage.

Along the same lines, its compact structure and massive functionality also make room for more devices in your workplace. With this, you can afford to double up the workforce to eventually double up the results. Alternatively, you can say it saves up physical space. Thus, making your studio a manageable place.

Things to Consider

Now that you have a firm motive and a clear picture in your mind – let’s get to the shopping guide. You’re sure you want a NAS device. But you’re not sure how to get it. The list of features below aims to assist you with the very question.

When considering a certain model, assess the following aspects as per the given standards:

Build Quality

best 5 bay nas for plex

Firstly, you need to assess the build quality. Although most NAS are high-end devices and feature complex, delicate technology, you need to look for something sturdy. Unless, of course, you’re the only one who uses the NAS devices.

You can assess the robustness of the NAS device by analyzing the materials used to build it. Some of the preferred materials include hard-plastic and alloys of metal, such as aluminum alloy.


Usually, NAS devices come with two kinds of ports, i.e., USB ports and Ethernet ports. The USB ports enable connectivity to external storage devices or printers.

Note that, when looking at NAS devices, you should look for a greater number of USB ports as they increase the functionality. Remember, a 3.0 USB port works better than a 2.0 USB port. But a 2.0 USB port works well for printing. Also, avoid looking for wireless connectivity ports.

They will cost you more for no good reason. That’s because wireless connectivity negatively impacts a NAS device’s functionality. The wired connections make smooth and efficient data transfer possible. Hence, it’s best to stick with wired versions.

Transfer Speed

qnap 5 bay nas

The transfer speed refers to how quickly NAS can read, write, and shift the data. Different NAS devices have different transfer speeds. Some models can transfer a maximum of 400MB/s, whereas some can only handle up to 250MB/s.

Usually, a transfer speed between 100 to 200MB/s works well for personal use. However, for corporate usage, a range of 350 to 500MB/s is recommendable.

Data Safety

Perhaps, the greatest benefit of NAS devices is their ability to use RAID technology. RAID is a short form for a Redundant Array of Independent Disks. This particular technology enables the NAS system to replicate the stored data in multiple hard disks. Hence, protecting the data in the case on disk mechanism fails.

In case of disk failure, RAID technology will restore the data of the previous disk into a new one. However, RAID has various functionality levels. For example, RAID 0 allows you to replicate the stored data on all hard disks that increases performance. But, if one disk mechanism fails, all will fail together.

In contrast, RAID 1 prevents such a situation and keeps one hard disk prepared in case of failure.

There are several other RAID modes, from 1 to 10. Each has its pros and cons. Hence, when purchasing a NAS system, do not forget to look into RAID technology if data replication is of immense importance.

Other than RAID, network-attached storage devices also come with other data safety features. These include cloud storage and backup to various gadgets.

Frequently Asked Questions
