What is a concatenated disk set?
Concatenation or spanning of drives is not one of the numbered RAID levels, but it is a popular method for combining multiple physical disk drives into a single logical disk. It provides no data redundancy. Drives are merely concatenated together, end to beginning, so they appear to be a single large disk.
What is concatenated RAID?
2.1. RAID Type: Concatenation Concatenations are also know as “Simple” RAIDs. A Concatenation is a collection of disks that are “welded” together. Data in a concatenation is layed across the disks in a linear fashion from on disk to the next.

Is JBOD the same as RAID 0?
The difference comes down to what you need: RAID 0 provides better performance by spreading data across multiple drives in the RAID for faster writing and reading. This is important for high audio track counts and video applications. JBOD creates one large “logical” drive from several smaller drives.
Can I change from JBOD to RAID?
Your only way to do what you want is to copy the data off to a separate second device (an external USB hard drive or some suitable network/cloud storage), then reformat the MCM to RAID1 and then copy the data back again.
