What’s the best RAID?



You would like to build a drive array configuration that provides the highest levels of throughput. You don’t need the RAID array to provide any redundancy if a drive fails. What RAID type would be the best fit?

A) RAID 0

B) RAID 1

C) RAID 5

D) RAID 1+0

E) 25 player (Heroic)


The answer: A) RAID 0

RAID 1 (mirroring) and RAID 5 (striping with parity) both provide redundancy if you lose a hard drive. RAID 0 (striping) provides high performance, but there’s no redundancy if a drive crashes.

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.
