Raid 0 vs. Raid 1

RAID (Redundant Array of Independent Disks) refers to storage technology. Here, every RAID level comes with its special characteristics.

For common system users, Raid 0 and Raid 1 are widely chosen ventures. If users cannot decide which one to choose from these two options, refer to this blog, where we have compared Raid 0 vs. Raid 1 in five different aspects.

RAID (Redundant Array of Independent Disks) is a perfect option for users who like to enhance their storage performance in all aspects. Also, Raid 0 and 1 are two average projects which can satisfy your needs.

If you face data corruption, such as corrupt pst files, and look for an Outlook solution, you can opt for data redundancies in a Redundant Array of Independent Disks. Therefore, you have to choose which one is best for you.

So, look at this Raid 0 vs. Raid 1 comparison and find the perfect project for you.

Raid 0 vs. Raid 1

Part 1: Raid 0 vs. Raid 1: Spot Main Differences

Here’s a detailed comparison of Raid 0 and Raid 1 arrays. In this comparison, we discussed five major features when choosing the best Raid for your system.

1. Main Feature

When we talk about Raid 0, data is evenly barred in all hard disks of the array. However, in the Raid 1 project, your data is barred and stored integrally in the array’s each hard disk.

To put it in perspective, your Raid 0 corrupts when any hard disk face errors. In that case, users are going to suffer from data loss.

On the other hand, in the case of Raid 1, if a single hard drive becomes corrupted, your other drives would not be suffered at that time. Thus, users can protect their data as quickly as possible.

2. Reliability

In terms of Raid 0 vs. Raid 1, the former offers better reliability than the latter due to redundancy. Or one can say that the data is secure in Raid 1 when hard drives fail.

Apparently, Raid 0 cannot guarantee that because it does not have redundancy. However, you should know that RAID arrays will not secure your data from the storage media’s gradual decay.

3. Reads

When it comes to Raid 0 vs. Raid 1 reads, Raid 0 works faster than Raid 1. Actually, the array’s read speed is the total transfer speed of all disks. Therefore, in the best situations, just the RAID controller limits the speed.

On the other data, redundancy in the Raid 1 project slows down its speed. Here, the speed just reaches the same as one hard drive.

4. Writes

In Raid 0 vs. Raid 1 comparison, it is time to discuss writes. The data is written and split evenly to all hard drives in the case of Raid 0, whereas each disk stores the whole data in Raid 1 as a single copy.

Therefore, Raid 0’s write speed is way faster when you compare it to that one of Raid 1. Also, it is just the same when you write to one hard drive of Raid 1.

5. Storage

In Raid 0, the sum of all hard drives’ storage volumes equals the entire storage. In the case of Raid 1, the entire storage turns out to be the same as any hard drive. This is because every hard drive in the array keeps all the stored data inside.

Therefore, if you find out that if you own a large amount of data that needs to be stored, Raid 1 asks for more hard drives than the other one.

Part 2: Raid 0 vs. Raid 1: Which is the Best Version?

Most people ask about Raid, which is the storage technology. This technology combines various disk drives to form a single one.

RAID features two primary configurations, where each one comes with its own features. So, which RAID version is the best? Most people recommend Raid 0, but it features no data protection.

Also, which one to choose if you want protection and speed? People even get confused when they read that while using RAID, it is recommended not to write to the array.

So, these are a few questions people seek questions when they come across Raid 0 vs. Raid 1. As stated above, Raid 0 and Raid 1 are two primary RAID configurations. Now, let’s discuss these two separately in detail!

Get to Know About Raid 0

In our Raid 0 vs. Raid 1 comparison, it is best to know more about Raid 0. This RAID version is a blend of two hard drives as one drive.

For instance, one 2TB hard drive comprises two 1TB drives. Raid 0 surges sequential write and read speeds. However, Raid 0 even doubles the failure risk because either drive failure could lead to all the data loss.


While RAID 0 doubles up your write and read speed theoretically, in the actual world, it is not really noticeable. It turns out to be noticeable when you transfer large video files. However, it offers a few advantages of introducing added risk and higher chances of failure.

The only benefit of having Raid 0 is its operating system, which views the entire Raid array as a single large hard drive. Thus, it becomes a bit easier to keep your files organized.

Therefore, Raid 0 is great to use if you constantly back up your entire data. In that case, you would not mind losing it. Also, it helps you transfer large files at all times and when you require extra speed.

Know More About Raid 1

Let’s move forward with our Raid 0 vs. Raid 1 comparison. The Raid 1 version duplicates the data among two hard disks.

For instance, a single 1TB hard drive combines two 1TB drives. It offers the same reading speed benefit as the Raid 0 version. However, there is no advantage when it comes to writing speed.

Here, users lose half their space; however, if any of these drives fail, they will not lose any data. Also, their system will continue to work as normal. For this reason, Raid 1 is a pretty great option for people who remain concerned with data loss.


On the other hand, if you are thinking of getting two or more hard drives, then Raid 5 seems to be a great option. The Raid 5 version is an incredible compromise where you will enjoy most of the speed and protection benefits.


A single drive can sometimes fail, and your data remains intact. Also, you enjoy most of the storage space here.

For instance, if you own three 1TB hard drives in the Raid 5 version and you end up using 2TB storage, the speed of two drives in the Raid 0 array and any drive could fail while all your stored data remains intact.

If you lose all the data because of drives dying, you will find various companies, such as Raid 5 Data Recovery, which will help you retrieve the lost data. So, it is recommended to go with Raid 5 if you think of implementing the RAID system.

Also, if you are thinking about whether to write to the array or not, then the answer is yes. In some special cases, it is not recommended to write to the array.

For instance, it could be when you own an SSD in your system, where this SSD works way faster than a Raid array. Otherwise, it is all good to do so.

Frequently Asked Questions (FAQs):

  1. What is the primary purpose of RAID 0? RAID 0 primarily aims to improve performance by striping data across multiple drives, allowing for faster data transfer rates.
  2. Is RAID 0 or RAID 1 more secure? RAID 1 is more secure than RAID 0 since it provides data redundancy. In RAID 1, if one drive fails, the mirrored drive(s) maintain a copy of all the data.
  3. Can I mix RAID 0 and RAID 1 drives? No, RAID 0 and RAID 1 drives cannot be mixed. Each RAID level requires a specific configuration.
  4. Which RAID level is best for gaming? RAID 0 is often preferred for gaming as it offers faster data access and improved performance, resulting in reduced loading times and smoother gameplay.
  5. How do I set up RAID 0 or RAID 1 on my computer? The process of setting up RAID 0 or RAID 1 varies depending on your computer’s hardware and operating system. It is recommended to consult your computer’s user manual or seek guidance from a professional for the specific steps to configure RAID on your system.


For people who like to integrate the RAID array into their build, it is best to install Windows and other important programs on the SSD. Also, use an HDD to store data.

If users like redundancy, it is best to add an extra drive in Raid 1 or back up things regularly to external HDDs. If you are still confused with Raid 0 vs. Raid 1, mention your queries in the comment below.

So, this is all about Raid 0 vs. Raid 1 comparison. In this article, we have talked about each and every aspect of these two Raid versions.

Go with Raid 0 if you care about the speed, and choose the other if your priority is security. Now, choose the best one as per your requirements and preferences.
