Note : To install a new disk when the server is running, first be sure
the disk volume is in the "degraded" mode. Or, wait to hear two long
beeps after the disk crash and then insert the new disk in place of
the failed disk.
RAID 6
The RAID 6 group is ideal for critical data protection needs. To create
a RAID 6 group, a minimum of 4 hard disks are required. The total
capacity of the RAID 6 group is equal to the size of the disk with the
smallest capacity in the array times the number of (hard disks – 2). It
is recommended (though not required) that only hard drives of the
same brand and capacity are used to establish the most efficient
hard drive capacity. RAID 6 can survive 2 disk failures and the system
can still operate properly.

RAID 10
RAID 10 is a combination of RAID 1 (mirroring) and RAID 0 (striping),
without parity. RAID 10 is a stripe across a number of disks to provide
fault tolerance and high speed data transfer. The storage capacity of
a RAID 10 group is equal to the size of the disk with the smallest
capacity in the array times (the number of hard disks in the array/2).
It is recommended that only hard disk drives of the same brand and
capacity are used to create a RAID 10 group. RAID 10 is suitable for
high volume transaction applications, such as a database, that
require high performance and fault tolerance. A maximum of 2 failed
disks from 2 different pairs are allowed in RAID 10.
