RAID 5 vs RAID 10: Difference and Comparison

The RAID( Redundant Array of Inexpensive Disks or Redundant Array of Independent Disk) is a single unit of many physical drives in a virtual manner. The RAID has different levels to increase the work.

The RAID gives as a replacement for losing your data.RAID backup the data to the connected physical drives. The RAID provides improved performance and creates redundancy.

Striping, parity, and Mirroring are Provided by RAID to enhance efficiency. RAID has many different configurations but has become old. More modern technology is introduced nowadays.

People run like rabbits, and RAID is the tortoise.

Key Takeaways

  1. RAID 5 uses parity to protect against data loss, while RAID 10 uses mirroring and striping.
  2. RAID 5 requires a minimum of three drives, while RAID 10 requires a minimum of four drives.
  3. RAID 10 provides better performance and fault tolerance than RAID 5 but is also more expensive.

RAID 5 vs RAID 10

RAID 5 is a type of RAID (redundant array of independent disks) that uses block-level striping and parity data across multiple disks. In RAID 5, data is spread across several disks. RAID 10, also known as RAID 1+0, is a combination of RAID 1 and RAID 0. It combines mirroring and striping to provide both redundancy and performance. In RAID 10, data is mirrored across two sets of disks.

RAID 5 vs RAID 10

The RAID 5 has a storage capacity of 6TB. That results in high performance and helps to cover drive failures. The RAID 5 can balance both the process of reading and writing.

It has more workable storage compared to other raids. The RAID 5 is the most secure because the files are shared across all drives. The failed data can be recovered by parity data.

The data here are stored only once and then duplicated by mirroring.

The RAID 10 has a minimum of four disks and no count in maximum. It is mirroring data with striped disks. The services like email need high performance which is provided by RAID 10.

It balances both the read and write process with high speed. RAID 1+0 is another name for RAID 10 with a combined called nested configuration.

What is RAID 5?

In RAID 5, the data isn’t protected much. RAID 5 gives a commensurate performance of RAID 0. RAID 5 cannot create a new array.

It has a combined unit called parity and stripped which results in good redundancy. Three disks are needed by RAID % at minimum.

The two drives present first can make them equal by themselves and then transfer data to the third drive.

The RAID can do a replacement of failed drives without wasting time. The arrays present in parity are not equal in properties.

Those are determined by members present inside the parity data.
RAID 5 has the advantage of recreating the data. The RAID 5 takes more time to recreate the data.

The recovery is impossible if a drive loses data once.

RAID 5 is famous among all the RAIDS. It can combine the best elements to give better efficiency within the various RAIDS. It can also read the data that is present in some other devices.

RAID 5 is categorized into four different parts. The disk will be swapped with data present in them. In simple it is an all-rounder.

What is RAID 10?

In RAID 10, the data are striped and mirrored. RAID 1+0 is the other name of RAID 10. If two disks are mirrored, then data will be lost due to no parity; instead mirror can take the responsibility here.

The minimum requirement of the disk is four, and no count is the maximum. The mirror can make a copy called mirror copy which helps in the protection of data loss.

The RAID 1+0 and RAID 0+1 are equal and present in the opposite order in the layer. These both use an equal number of RAID levels.

The storage capacity of RAID 10 is 20TB. The first 10TB is for live data, and the remaining 10TB is for mirror copy. The levels present inside the RAID didn’t use the mirroring process.

There is an alternative for RAID 10 that is called JBOD(Just a Bunch Of Disks).

The disk mirroring in RAID 10 is to duplicate the data and make a copy in every single storage connected to the controller.

Mirroring can create one more layer of protection against data loss and help in the fast recovery of data in case of failure.

The RAID 10 boosts the speed of processing and gives a better performance in time.

Main Difference Between RAID 5 and RAID 10

  1. RAID 5 uses parity data for data redundancy, and RAID 10 uses mirroring for data redundancy.
  2. RAID 5 has three minimum disks, and RAID 10 has four minimum disks.
  3. RAID 5 reads and writes data, but RAID 10 does faster than RAID 5.
  4. The blocks are stripped in RAID 5, and the blocks are mirrored in RAID 10.
  5. RAID 5 causes a risk of data loss, but RAID 10 gives better protection.
