The example shows that the RAID striped volume is online and functioning.
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 fashion. If
any one disk is lost, all data on the volume is lost. For this reason, RAID 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.
