Students have asked these similar questions
Which of the following statements about RAID 1 are correct? Check all that apply.
Group of answer choices
a. Increased fault tolerance compared to a single disk or RAID 0
b. Reduced cost per GB
c. Increased write performance compared to a single disk
d. Increased read performance compared to a single disk
Parallel attempts are made to write sections of a file to separate hard drives. Is there a reason why doing so is so crucial for magnetic disks? Do we still need to use SSDs if they are readily accessible, or is it a waste of time? How come this is the case?
2.

a.
RAID level 1
b.
RAID level 2

Before adding the redundancy data, our RAID drive has 4 disk drives. If we choose RAID 1, how many extra drives do we need to add to store redundancy? RAID 5? RAID 6?b. We decide to use RAID 0 because we want our RAID drive to support multiple accesses as much as possible (that is, multiple different processes accessing disk simultaneously).

It's crucial to accomplish this with magnetic drives because, without using them, do you really value SSDs? Justify this observation.arrow_forward
