Raid 5 Vs Raid 10: A Detailed Guide

Raid levels are the way to combine different disks, and you can implement these levels through the software and hardware.

But when it comes to choosing between the Raid levels, there are certain factors that we should consider.

Here I am going to compare Raid 5 Vs. Raid 10 and give you every possible detail related to these levels.

You can also check which Raid level uses parity for data protection or which raid type doesn’t use parity for data protection and then choose one as per your need.

But first of all, check what Raid is in a nutshell.

What is Raid?

Raid stands for Redundant array of independent disks.

It is a setup that consists of multiple disks for storing data that are linked together to enhance the performance level and prevent data loss.

Due to this multiple disk usage, there is disk mirroring, parity, and data stripping.

Now let us compare Raid 5 vs. Raid 10 and know all these levels.

What is Raid 5?

raid-5

In Raid 5, 3 minimum physical disks are required. The data is equally distributed amongst all the disks.

There is no need for space to mirror the data. Raid 5 can efficiently utilize the storage.

Raid 5 setup can balance the security, storage, performance, and deliver a good configuration.

Raid 5- Pros

  • Raid 5 uses data striping with equality and provides fast reads.
  • This setup balances storage, security, fault tolerance, and performance very efficiently.
  • Raid 5 is cost-effective compared to other Raid levels.
  • It stores data efficiently.

Raid 5- Cons

  • As Raid 5 distributes the data equally amongst all the disks so, it is time taking.
  • The writing performance of Raid 5 is comparatively slow.
  • The process of implementation is quite complex.

What is Raid 10?

raid-10

Raid 10 is a combination of Raid 0 and Raid 1. In Raid 1 the data is mirrored, and in Raid 0 the volume across the disks is striped to enhance performance.

As Raid 10 combines both, it possesses all the advantages of the said Raid levels to offer more fault tolerance and boost the performance level.

Raid 10-Pros

  • Raid 10 provides enhanced performance.
  • In Raid 10, data can be read and written simultaneously.
  • Your data remains secured and there is no data loss.

Raid 10-Cons

  • Raid 10 required more disks for implementation.
  • Since the data is mirrored in Raid 10, so, you can use only 50 percent of the storage.
  • Raid 10 level is comparatively expensive.

Raid 5 Vs Raid 10

Each raid comes with its advantages and disadvantages. It is all about which suits your setup and purpose.

Raid 5 and Raid 10 rebuild data differently. If a disk fails, Raid 5 reads data from the other disks.

It uses parity information throughout the disks and reconstructs the data.

So, this consumes much time and puts a heavy load on your system. So your system becomes prone to crashes and disk failure.

In Raid 10 configuration, the data is read from the mirror disk. It copies the same data to the disk that is being replaced.

So, no alteration occurs in the read or write operations.

But when it comes to storage, Raid 5 stores the data with more efficacy since Raid 5 uses parity information.

Raid 5 only requires a minimum of 3 disks, but Raid 10 requires more disks.

As a result, Raid 5 balances storage, security, fault tolerance, and performance very efficiently.

Raid 10 is also more expensive compared to Raid 5.

Some Factors To Consider Before Choosing Raid 5 Or Raid 10

Both the Raid levels have their advantages and disadvantages.

You need to choose as per your requirements. Let us check some pertinent factors before choosing between the two levels.

Disk Failure

If there is multiple disk failure then Raid 5, then you can recover your data easily but in Raid 10, it is not possible if multiple disks fail simultaneously.

If there is a single disk failure, then raid 10 is a good choice as Raid 10 can reconstruct the data much faster.

Because of the parity checks, Raid 5 will take a much longer time to do so.

Read Or Write Operations

If you need faster read or write operations for your applications, then Raid 10 will be a good choice.

It does not require parity checks, so it is faster than Raid 5.

Simplicity

Raid 10 is much simple that Raid 5. All you need to do is combine raid 0 and raid 1 to get the setup.

Raid 5 is a bit more complex than Raid 10.

Storage And Backup

For a good backup and storage Raid, 5 is a better choice. It provides much more efficient storage. In Raid 10, so, you can use only 50 percent of the storage.

Budget Friendliness

Raid 10 requires a minimum of 4 disks, whereas raid 5 requires a minimum of 3 disks.

Besides, Raid 10 uses 50 percent of the storage, so Raid 5 is cost-effective and budget-friendly.

Performance And Data Security

For production and hosting servers, Raid 10 is a good choice. It provides enhanced performance and better data security.

But for the file and application servers, Raid 5 is the best choice.

It balances storage, security, fault tolerance, and performance very efficiently.

Closing Up

Hope the comparison between Raid 5 vs. Raid 10 helped you to decide which one is suitable for you. So, consider the factors and make a choice accordingly.
