RAID

Jump to Comments

Just a quick post for those of us who come across RAID and seem to freakin’ forget what the levels mean:

A quick summary of the most commonly used RAID levels:

• RAID 0: Striped Set
• RAID 1: Mirrored Set
• RAID 5: Striped Set with Distributed Parity

Common nested RAID levels:

• RAID 01: A mirror of stripes
• RAID 10: A stripe of mirrors
• RAID 30: A stripe across dedicated parity RAID systems
• RAID 100: A stripe of a stripe of mirrors

Thank you Wikipedia.
