RAID is an acronym for Redundant Array of Independent (or Inexpensive) Disks. It is a method of storing information on multiple hard disks for greater protection and/or performance.

Which is better RAID 1 or RAID 5?

Raid 1 can tolerate more than 1 disk failure, while Raid 5 allows fault tolerance of only 1 disk. Raid 1 has slow write speeds when compared with Raid 5. Raid 5 has good failure resistance and better security. The performance is great in Raid 1, but in Raid 5, performance is slow due to disks’ redundancy.

Why RAID 10 is the best?
