Answer:
RAID level 5 can be used to compensate a limited number of available disks.
Explanation:
There are two type of RAID
Software RAID
deliver services form the host.
Hardware RAID
provides hardware services.
RAID has levels
0, 1, 5, 6, and 10
RAID 0, 1, and 5 work on both HDD and SSD media,
4 and 6 also work on both media.
RAID 0 :Striping
In this level minimum of two disks,RAID 0 split the file strip the data.Multiple hard drive are used to split the data.
RAID 1 : Mirroring
In this level Minimum two disk require and provide data tendency.
RAID 5 :Stripping with parity
Parity is a binary data.RAID system calculate the value which system used to recover the data.
Most RAID system with parity function store parity blocks.
RAID 5 combines the performance of RAID 0 with redundancy of RAID 1.
RAID 5 level should minimize the fault tolerance.
