Under RAID 0 (disk striping), there is no replication of data across drives. The
data is written to the RAID volume across all member disks in a round-robin

0 cannot be used to ensure data integrity or availability, but can be used to
increase write performance in some scenarios.
For more information about the raidctl utility, see the raidctl(1M) man page.
Note – The logical device names might appear differently on your system,
depending on the number and type of add-on disk controllers installed.
