Does RAID 0 lose disk space?
RAID 0 has no loss of space on the disks.
What is RAID 1?
RAID 1 provides full redundancy.
What is RAID 5?
Striping with parity; one disk can be lost without losing any data.
What is RAID 6?
Double striping with parity; two disks can be lost without losing any data.
What is RAID 10?
RAID 10 provides redundancy and performance.
What is failure resistance in RAID?
Protection against the loss of erased data (RAID 1/RAID 5).
What is fault tolerance in RAID?
RAID can function even when a component fails (RAID 1/RAID 5/RAID 6).
What is disaster tolerance in RAID?
RAID with two independent zones with full data access (RAID 10).
What do RAIDs provide?
Redundancy and high availability.
