What Is RAID 10 and What Are Its Benefits?

Dave updated on Jul 25, 2022 to Knowledge Center

From 0 to 9, numerous RAID levels give distinct benefits depending on how the disks are linked or how the settings are established.

This essay will focus on RAID 10, among the most often used RAID levels. We will discuss RAID 10 and its key benefits and drawbacks in detail in this article.

What Is RAID 10

In essence, RAID 10 is a mixture of RAID 0 and 1. Remember that RAID 0 uses striping to distribute data across many disks to improve efficiency, while RAID 1 uses disc mirroring to duplicate data.

This is what RAID 10 does: it combines both of these capabilities. It can also read and write data more quickly than RAID 5 since RAID 10 does not need parity management.

Keep in mind that many individuals mistakenly assume that utilizing RAID 10 (or any other RAID level) is equivalent to creating a backup. This is because if one drive is contaminated, the data on the other driver is also susceptible to corruption.

For a backup to be real, it must be possible to restore damaged data before it is duplicated and saved in another place.

"Practicing solid online application security tactics like integrating backup servers or exploiting server traffic rerouting technologies would be a smart idea before an assault occurs," says Mark Preston of Cloud Defense, a cybersecurity specialist.

Having administrators use distinct accounts for various activities, such as backing up data, is another option to explore.

Advantages of RAID 10

  • Striped arrays with RAID 1 segments are used to build RAID 10.
  • Mirroring with RAID 10 has the same fault-tolerance overhead as mirroring with RAID 10.
  • It is possible to get fast I/O throughput by striping the RAID 1 component.
  • Multiple disk failures may be tolerated in a RAID 10 array under specific conditions.
  • An excellent alternative to RAID 1 for sites that need a speed increase but don't want to use RAID 1.

Disadvantages of RAID 10

  • RAID level 10 can have extremely high overhead and associated costs.
  • Because all the drives need to move in tandem for the track to function properly, sustained performance will suffer.
  • Scalability is quite constrained, and the intrinsic cost is extremely high.

When Should Raid 10 Be Used

Because it does not handle parity and hence does not need any checks, RAID 10 is the optimal solution for situations where applications need to do read/write operations at high speeds. RAID 10's read performance is twice as quick as RAID 5's.


In conclusion, RAID 10 is a hybrid system that combines RAID 0 and RAID 1 to provide exceptional fault tolerance and performance.

RAID 10 is excellent for production and hosting servers due to its performance and data security since it needs more disks, which makes it costlier. However, because of its performance and data security, RAID 10 is more perfect.
