$11.(10)$ RAID systems are defined and described in Module $11$ Lectures Part $2.$

A RAID system is to be constructed using some number of identical disk drives each of which

can hold $16$ terabytes of data. The disks in each system as a group must hold a large database of

size $128$ terabytes along with any required parity. What is the minimum number of disks required

to hold the combined data and required parity if the disk system is implemented as a:

a$)$ RAID$0$ system? Minimum number of disks required $=\_\_\_$

b$)$ RAID$6$ system? Minimum number of disks required $=\_\_\_$

c$)$ RAID$4$ system? Minimum number of disks required $=\_\_\_\_$

d$)$ RAID$5$ system? Minimum number of disks required $=\_\_\_\_$

e$)$ RAID$1$ system? Minimum number of disks required $=$
