E) 5 disks? That's way too many. The question clearly says "minimum".

D) 4 disks is the minimum for a fully redundant RAID5 array. I'm pretty sure about this.

I remember reading that RAID5 can survive one disk failure, so it has to be at least 3 disks. I hope that's correct!

I thought it was 3 disks too, but I keep mixing it up with RAID10. This is tricky!

I'm not too sure, but I feel like it might be 4 disks. I practiced a question like this before, but I can't recall the exact details.

I think RAID5 needs at least 3 disks, right? I remember something about needing one for parity.

Hmm, I'm not too sure about this one. I know RAID5 needs multiple disks, but I can't remember the exact minimum. I'll have to think it through carefully.

I've got this! The minimum number of disks for a fully redundant RAID5 array is 4. The parity data is distributed across all the disks, so you need at least 4 to have full redundancy.
