You need a disk array that will provide for the best read and write performance, with no need for redundancy. Which of these RAID types would fit your requirement?
A) RAID 0
B) RAID 1
C) RAID 5
D) RAID 5+5
E) Floppy disks should work for you
The answer: A) RAID 0
RAID 0 stripes your data between separate physical drives, increasing the throughput of the read and write process. Unfortunately, there’s no redundancy; a drive failure breaks the entire array and renders your data unavailable.

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. |
