RAID

RAID stands for Redundant Array of Independent Disks.

Many of our products feature the following levels of RAID:

  • RAID 0
  • RAID 1

This article explains the main difference between these raid levels along with an easy to understand diagram.

In all the diagrams mentioned below:

  • A, B, C, D, E and F – represents blocks
  • p1, p2, and p3 – represents parity

RAID LEVEL 0


Following are the key points to remember for RAID level 0.

  • Minimum 2 disks.
  • Excellent performance ( as blocks are striped ).
  • No redundancy ( no mirror, no parity ).
  • Don’t use this for any critical system.

RAID LEVEL 1

  • Minimum 2 disks.
  • Good performance ( no striping. no parity ).
