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.

Want to know more? Watch “RAID.” 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. |
