RAID Types A+ 1001
Ready!
RAID
Redundant Array of Independent Disks
RAID 0
Striping, File blocks split between two or more drives Fast No Redundancy Single drive failure crashes system
RAID 1
Mirroring, File blocks duplicated between two or more drives, High Redundancy
RAID 5
Striping with Parity, File blocks are striped with Parity block, Minimum 3 disks, High redundancy, Can be slow
RAID 10 1+0
Speed of Striping with redundancy of mirroring, Minimum of 4 disks
Mirroring
Replicating data on two or more disks
Striping
Dividing data into blocks and storing on multiple disks
