The order of the hard drives in the system is important because it helps you identify the faulty drive.
Take a look at the table below of the fault tolerance of different RAID levels:
RAID
Minimum
disk
requirement
Maximum number of failed drives
(without data loss)
11
2
No fault tolerance
(1 drive failed and data loss occurred)
11
2
1 (mirrored pair)
11
3
1
11
4
2
IMPORTANT!
Knowing the location of your drives is vital. There is a risk of data loss if you mistakenly
remove 2 drives from a RAID 5 logical drive.
