A company has client computers that run Windows 10.Each computer has two hard drives.
You need to create a dynamic volume on each computer that maximizes write performance with data fault
tolerance.
Which kind of dynamic volume should you create?
A.
Striped Volume
B.
RAID 5 Volume
C.
Spanned Volume
D.
Mirrored Volume
Correct
D, is correct.
If PC had 3 disks, answer would be: B, Raid 5.
But with this situation: Answer D is correct.
A and C have no fault tolerance.
This is RAID1 a mirror setup. The read speed can be better, write speed is the same as a single drive.
Mirroring (RAID1) stores two identical copies of data on two hard drives. Should one of the drives fail, all the data can be read from the other drive. Mirroring does not use blocks and stripes.
READ SPEED can be improved in certain implementations, because read requests are sent to two drives in turn. Similar to RAID0, this should increase speed by the factor of two. However, not all implementations take advantage of this technique. +
WRITE SPEED on RAID1 is the same as the write speed of a single disk, because all the copies of the data must be updated

This is a nice interface and explains it to you.
