The MegaRAID SATA 300-4XLP supports disk arrays using
the following RAID levels:
• RAID 0 (Data striping): Data is striped across all disks
in the array, enabling very fast data throughput. There is
no data redundancy. All data is lost if any disk fails.
• RAID 1 (Disk mirroring): Data is written simultaneously
to two disks, providing complete data redundancy if one
disk fails. The maximum array capacity is equal to the
available size of the smaller of the two disks.
• RAID 5 (Disk striping with distributed parity): Data is
striped across all disks in the array. Part of the capacity
of each disk stores parity information that reconstructs
data if a disk fails. Provides good data throughput for
applications with high read request rates.
• RAID 10 (RAID 1 and RAID 0 in spanned arrays): Uses
mirrored pairs of disks to provide complete data
redundancy. Provides high data throughput rates.
