And additional driver store the parity information.
Advantage
Provide Large Data Transfer
Dis advantage
Too much costly
Performance is slower and random,
Required Min mum Drive :3

RAID 5 - PARITY ACROSS DISK
it is similar to RAID-3
Data are write into the across the disk with indepently.
Parity information write across the all the drive.
Dis Advantage
Capacity Yield
Required Min mum Drive :3
RAID 6- MAINTAIN TWO PARITY
Minmum No of Required Disk :4
Even though if two disk fail,
we can recover the data.
Difference Between RAID 5 AND RAID 3
Raid1 : parity stored only in one disk
Raid5 :Parity stored in the multiple disk.
