Assuming the same disk array hardware, which of these might be a reason to choose RAID 0 instead of RAID 1?
A) RAID 0 provides more available storage space than RAID 1
B) RAID 0 provides more redundancy than RAID 1
C) RAID 0 POSTs faster than RAID 1
D) RAID 0 includes built-in data security
E) RAID 0 is one less than RAID 1
The answer: A) RAID 0 provides more available storage space than RAID 1
RAID 0 splits files between drives, using all available disk space. RAID 1 duplicates every file, providing high redundancy but only half of the total disk space can be used for storage.

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.
