Redundant Array of Independent Disks, is a technology that uses multiple disks to increase performance and/or redundancy
What is RAID 0?
Striping, data is split between multiple disks to increase read and write speeds, no redundancy
What is RAID 1?
Mirroring, data is duplicated between multiple disks to create redundancy without increasing performance
What is RAID 5?
Striping with parity, stripes data while reserving a block for parity to ensure redundancy, a middle-ground solution between RAID 0 and RAID 1, requires at least 3 drives
What is nested RAID?
Using multiple RAID configurations in the same RAID array
What is RAID 10?
RAID 1+0, a nested RAID configuration that stripes and mirrors data, requires at least 4 drives
What is RAID 50?
RAID 5+0, a nested RAID configuration that mirrors a RAID 5 array, requires at least 6 drives
