Difference Between RAID 0 and RAID 1

Data StorageDatabaseBig Data Analytics

In this post, we will understand the difference between RAID 0 and RAID 1

RAID 0

  • It stands for Redundant Array of Independent Disk level 0.

  • In this technology, disk stripping is used.

  • This technology is inexpensive.

  • It doesn’t have a write penalty.

  • The relative storage efficiency of this technology is 100%.

  • The write performance of this technology is better than RAID 1.

  • It emphasizes on the speed of data access.

  • It provides good performance for read operation.

  • It doesn’t provide any protection.

RAID 1

  • It stands for Redundant Array of Independent Disk level 1.

  • This technology uses disk mirroring technique.

  • It is an expensive method.

  • It comes with a write penalty.

  • The relative storage efficiency of this technology is 50%.

  • The write performance of RAID 1 is lesser in comparison to RAID 0.

  • The emphasis here is on the availability of the data.

  • It gives moderate performance for read operation.

  • It provides mirror protection.
