There are lot of misused or understand of RAID levels JBoD is Just a Bunch of Drives, where you can see multiple drives the same box, this is a most confused non-raid term.

Years ago, some RAID manufacturers could not make a truly JBOD with their RAID engine, they call SPAN (BIG) as JBoD.

RAID1 is a Mirror RAID and it needs TWO HDD to mirror each other. Whereas CLONE is a Multiple Duplicate HDD with the same volume, example DAT Optic's eBOX, sBOX (hardware RAID). Hardware RAID boxes generally offer RAID 0, 1, 5, CLONE, Large, and Hot spare.

As for RAID 5/6, both have parity space portion equal to one drive for RAID5 and two drives for RAID6. Most common mistaken knowledge is that parity data is located in a dedicated drive(s). That is incorrect. The party space is divided equally among RAID the member HDDs. Example: RAID5 from five HDD, each of the drive will have 1/5 of space allocated for parity, whereas for RAID6 each drive will have a 2/5 of space allocated for parity. For those who want to argue, if there is a dedicated parity drive(s), let's assume there is, what happens to the RAID if the dedicated parity drive failed? The RAID can not rebuild because the data needs to rebuild is no longer there.

There is a lot of misunderstanding of RAID levels.
