Raid 10 minimum number of disks
In the exam cram book I am reading, it says that Raid 10 has a minimum number of 2 disks (usually 4).
I'm watching a Professor Messer video which suggests that the minimum number of disks is actually 4. I have also gotten this answer from various websites.
Can somebody clear this up for me? I assume that with Raid 10, you would normally utilise two sets of two drives, but all that matters at the moment is whether this is the correct answer for the Comptia A+ exam.
So, what is the minimum number of disks for a Raid 10 setup?

Raid 10 is also know as a "stripe of mirrors". If you only have 2 disks then you would only be able to create a stripe or a mirror but not both.

Note to everybody reading the David Prowse exam cram book. In the book, Raid 10 is said to have a minimum number of 2 disks, however, the minimum is actually 4.

But for classic, normal, sane RAID-10, yeah, you need minimum 4 drives.
