RAID 0
A RAID 0 is created by striping data across two or more disk drives.
This striping scheme creates no redundancy to protect the data.
However, because the drives share load equally, RAID 0 provides the
best read and write performance of any RAID type.

RAID 1
A RAID 1 array is created by copying, or mirroring, all data from one
drive onto a second drive. This mirroring provides redundancy,
ensuring that if one drive fails no data is lost. Redundancy also
means that only half of the total capacity is available.
RAID 1 offers no write performance advantage over a simple
volume configuration. However, because the drives share read load
equally, RAID 1 provides improved read performance.
