The MegaRAID SATA 150-4 RAID Controller supports disk
arrays using the following RAID levels:
• RAID 0 (Data Striping): Data is striped across all disks
in the array, enabling 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 hard drives.
• 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.
Note:
For more information about RAID levels, refer to
the MegaRAID Configuration Software User’s
Guide on the MegaRAID Universal Software Suite
CD.
