Reliable Array of Inexpensive Disks
Redundant Array of Independent Disks

What represents member disks in the RAID block layout diagrams?

table cells
rows
columns

Which of the following is the JBOD parameter set?

start offset, disk order
block size, disk order
start offset, block size

Check non-block RAIDs in the list

Span
Mirror
RAID0
RAID5

What is a minimum number of disks required to create a RAID?

2 disks
3 disks
1 disk

Speed improvement is achieved due to the fact that:

two data blocks on two disks can be read in one operation
each member disk in RAID is faster than a regular hard drive
data on a RAID is not fragmented

Can block size be 1 sector?

yes
no

What is start offset?

offset at which RAID user data starts
offset at which RAID metadata starts

What type of the device can implement exotic RAIDs?

high-end hardware
low-end hardware
software
