JBOD: A set of disks in the same disk cabinet, does not provide fault tolerance, raise the small, due to a jbod defect occurred raid.
Striped: Raid is a data stripe independent disk that classifies multiple drives into a single logical storage unit combination.
Levels: Each level has different cost, performance, and fault-tolerant benefits.

RAID0: There is no checksum for parallel transmissions.
RAID1: The capacity utilization ratio is half, redundant quantity is big.
RAID3: Parallel transmission, special disk parity, suitable for big data.
RAID5: Parallel transmission, non-special disk parity, suitable for small data.
RAID10: half RAID1 half RAID0.
