RAID 1

—In this configuration, all the data written to one disk is duplicated 

on the other disk. This offers greater data protection since if one disk fails, 
all your data is still intact on the other disk. However, using RAID 1 means 
only half your available disk space is used for data; the other half is used for 
a duplicate (mirror) of that data. 

You can use RAID 1 only if your storage system has only two disks. If the 
disks are not the same size, the smaller of the two disks is used for data, and 
the larger of the two disks is used as the mirror. If one disk fails, the other 
disk continues to make its data available. 

 

 

RAID 10

—RAID 10 is similar to RAID 1, but rather than having one disk 

mirror to one other disk, two disks mirror to the two other disks. 

You can use RAID 10 only if your storage system has four disks. The disks 
in the first two slots constitute the first pair, and the disks in the second two 
slots constitute the second pair. In each pair, the smaller of the two disks is 
used for data, and the larger of the two disks is used as the mirror. If one disk 
in the pair fails, the other disk continues to make its data available.
