JBOD and single disk mode sound like the same thing to me. (JBOD = just a bunch of disks).

RAID 0 has no fault tolerance at all. Your data is spread across two (or more) disks. Failure of any one disk causes all the data to be lost.

thanks for your reply, one more question

i have 3 WD Green HDD all of them are identical, same model same capacity (6 TB) and 1 WD Red HDD different model different type but same company same capacity (6 TB),

Will this be a problem ? i know that The SLOWER of the drives... will dictate the overall speed, other than that, is there any real problem to use different hard disks Models with the same capacity? please advice

It all depends on how you are using them. If you just format each disk with its own partitions then there is no problem (this is usually called JBOD). If you try to build some kind of RAID set then this could be problematic.
