Guide to Setup and Configure RAID on QNAP NAS

A detailed guide to familiarize you with what RAID is and its different levels for your QNAP NAS.

raid and its levels for your qnap nas

Data loss, without a doubt, is one of the biggest challenges associated with both small and large-scale businesses. The common reasons behind losing data include; power outages, software corruption, hardware issues, human error, and more. You will find multiple third-party tools claiming to protect your data when exploring the market. But you can’t simply trust all of them.

This is where QNAP RAID lends a helping hand. This mechanism consists of multiple levels, like QNAP RAID 1, QNAP RAID 5, and others. This article presents a detailed discussion of what RAID is and what its different levels do. Let’s gain insight into the specifics.

Part 1. What is the Difference Between RAID and QNAP NAS?

Well, RAID is a short form for a Redundant Array of Independent Disks. It is introduced by QNAP Systems, Inc., which is why it is commonly called QNAP RAID. RAID, with super easy configuration, prepares one logical storage unit by combining different drives to prevent data loss.

Structure of QNAP RAID

Different RAID types are supported by QNAP NAS. They provide you with various levels of data redundancy and performance. You have the option to choose hot configurations and single RAID (e.g., RAID 1, 5, and 6) based on the number of disks available in your NAS.

If your NAS has a QuTS hero operating system, it will offer great support for Triple Mirror and Tripe Parity. The Triple Mirror is known for providing mirroring protection for 3 disks, whereas Triple Parity protects 3 drives from failing.

What is the Main Advantage of RAID?

The biggest advantage of QNAP RAID is, of course, providing data protection. The best part of this protection is that it enhances the performance of a single disk by combining multiple drives together into a single logical unit. In addition, it uses a large number of lower-priced drives, making it a budget-friendly approach.

What is a QNAP NAS?

In case you don’t know, NAS is a shorter version of Network Attached Storage. As far as QNAP NAS is concerned, it is a system equipped with one or multiple hard disks. These drives are always connected to the internet. Moreover, it acts as a storage unit or a backup hub. It can carry different files, like music, videos, photos, and other similar data.

Differences between RAID and QNAP NAS

QNAP NAS is a system of one or more disks, as stated earlier. You can scale it up or down, keeping in mind your storage capacity. On the other hand, RAID backs up your data files by using multiple hard drives and does not offer support for protecting portable devices. They are unable to hold multiple disks, so using RAID on a personal level will be a costly approach.

Part 2. What are the Common RAID Levels?

This section presents a brief discussion on different levels of RAID, like QNAP RAID 0, QNAP RAID 1, QNAP RAID 5, QNAP RAID 6, and QNAP RAID 10. The pros and cons of these levels will also be part of this discussion.


If you prefer to work without a net, RAID 0 is a perfect option for you. It helps you spread the data across more than 2 hard disks. This RAID level prepares one giant unit for you to access by adding the storage capacity of 2+ drives.

qnap raid 0

Easy to use

Pretty straightforward

The support of an extra RAID controller is rarely required

Features the availability of all capacity

Offers good write and good read speeds


It does not offer a long-term solution

RAID 0 is not an appropriate solution for important data. You will lose the entire data if the disk fails.


It is known for providing a good balance of speed and redundancy. QNAP RAID 1 is perfect for home users. In addition, it is the favorite in most 2-Bay QNAP NAS devices. This RAID level needs at least 2 hard disks and you can only RAID them in pairs.

qnap raid 1

You can perform quick and easy recovery after replacing the drive.

It is easy to maintain consistent good and good write speeds.

Duplicates your 100% data when it is in operation.

Additional RAID is rarely needed.


If the enclosure is running, you can rarely replace a faulty or damaged drive.

Once you set up the RAID, you can access only half of its total capacity.


When setting up the storage array, QNAP RAID 5 is a top choice for both small and large-scale businesses. If you have four or more disks in the enclosure, this RAID level is recommended for you. Just like other RAID types, it spreads your data across multiple disks, but every stripe of the disk gives a small data nugget to one of the drives. This small data nugget is known as parity data.

qnap raid 5

You get access to excellent read speeds.

If a single drive fails, your data remains completely protected.

You can access the data when adding a new disk to the enclosure.


It takes more time to recover your data.

As far as the write speeds are concerned, they are below that of a single hard disk.


It is pretty similar to QNAP RAID 5 and uses the same principle as well. The use of TWO hard disks creates the difference. In the RAID type, the system duplicates the parity data on two disks. It is best to use for large-scale businesses that need more than 8 drives.

qnap raid 6

If one or two drives fail, your data remains completely secure.

Offers good read speeds.

You can easily access your data when introducing a new hard drive to the array.


Features slow write speeds.

Data recovery can take longer.

The storage of 2 drives gets lost.


It offers combined benefits of RAID 0 and QNAP RAID 1. Though it offers high-performance solutions, its cost vs. capacity margin is high compared to all other RAID levels. QNAP RAID 10 needs four hard disks. It maps them all in a 2x2 volume. If you are looking for easy data recovery, this RAID is a suitable option for you.

qnap raid 10

In case of data loss, you can perform quick recovery.

It can afford the loss of two disks if they are not paired.

Features good read and write speeds.


All the data will be lost if you lose two mirrored disks simultaneously.

Half of the available storage capacity gets lost.

Part 3. Why Do You Need RAID on Your QNAP NAS?

As mentioned earlier, RAID combines different small drives into one large storage unit. Your computer will see only a single drive instead of displaying multiple ones. RAID holds two different versions, i.e., Redundant Array of Independent Disks and Redundant Array of Inexpensive Disks.

The variation in the letters is due to the way the storage has changed. It is an inevitable fact that disk capacity has grown larger. As a result, the more recent trend of data storage arrays requiring redundancy has outweighed the need for constructing huge volumes. This is why you need RAID on your QNAP NAS.

Part 4. How to Set Up RAID in QNAP NAS?

It is super simple to set up a new RAID or change the RAID setup in QNAP NAS. This section presents a quick review of both setups.
