Question 1

stripped disks. distribures data accross multiple disks in a way that gives improved speed at any given instant

Answer 1

Raid 0

Question 2

mirroring the contents of the disks, making a form of 1:1 ratio real time backup. this is also called mirroring

Answer 2

Raid 1

Question 3

Striped disks and designated parity. Combines 3 or more disks in a way that protects data against loss fo any one disk. Fault tolerance is achieved by adding an extra disk to the array and dedicating it to storing parity information. The storage capacity of the array is reduced by one disk

Answer 3

Raid 3 or 4

Question 4

stiped disks with distributed parity. combines 3 or more disks in a way that protects data against the loss of any one disk. it is similar to raid 3 but the parity is not stored on one dedicated drive array. the storage capacity of the array is a function of the number of the drives minus the space needed to store parity

Answer 4

Raid 5

Question 5

Stripped disks with dual parity. combines 4 or more disks in a way that protects data against loss of any two disks

Answer 5

raid 6

Question 6

is a mirrored raid 1 and a stripped raid 0. requires a minimum of 4 drives. 2 mirrored and 2 stripped

Answer 6

raid 10
