RAID 0
RAID level 0, which is also referred to as " data striping", defines the simultaneous reading and writing of data blocks on multiple hard disks without parity control.
In striping, the individual data blocks ABCDE... are distributed to the hard disks( HD) one after the other. Data block "A" on HD1, "B" on HD2 etc.
The RAID 0 controller stores this data continuously on the hard disks in the disk array. This makes it possible to access two or more disks simultaneously, reducing read and write access times. RAID 0 is not data redundant, so if one disk fails, all data stored on it is lost. The principle is throughput-increasing but not fault-tolerant.
