Which of the following RAID levels does NOT provide fault tolerance?

Which of the following RAID levels does NOT provide fault tolerance?

• RAID 1
• RAID 0
• RAID 5
• RAID 10 

EXPLANATION

RAID 0 can be used for setups like those big, read-only network file system servers, or if mounting multiple disks is not possible. In RAID 0, data files are broken down into smaller blocks, and each block is written to a separate physical disk drive. This process is known as striping and is called a striped disk array configuration. This can increase I/O performance by spreading the load evenly (more or less) across many drives and channels, so large data can be simultaneously accessed from the different drives and put together quickly, as opposed to a single drive reading a large file one chunk after another. RAID 0 offers great I/0 performance, but has little to no fault tolerance.
