You need to design a drive array that will continue to operate if any drive fails. Which RAID types fit this requirement? Pick two.
A) RAID 0
B) RAID 1
C) RAID 5
D) RAID 1+1
E) RAIDers of the Lost Ark
The answers: B) RAID 1 and C) RAID 5
RAID 0, or striping, provides high performance but a single drive failure breaks the array. RAID 1 and RAID 5 both continue to operate, even if a single drive fails.

RAID arrays are common ways to provide high-throughput and redundancy for groups of hard drives. In this module, you’ll learn how the different RAID technologies can be used to build large-scale storage infrastructures. You’ll also learn the advantages and disadvantages of the different RAID technologies and how hardware and software RAID compares.
