You’d like to build a server that provides redundancy in the case of a drive outage, but you also want to maximize the amount of available space on the disk array. Which of these RAID types would fit this requirement?
A) RAID 0
B) RAID 1
C) RAID 5
D) RAID 1+0
E) If you keep two computers at your desk and duplicate everything you do, you’ll have perfect redundancy
The answer: C) RAID 5
RAID 5 stripes data across multiple drives, using a separate drive for parity information. This allows for complete redundancy without the need to duplicate the data.

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. |
