What is JBOD?

JBOD (which stands for “just a bunch of disks”) generally refers to a collection of hard disks that have not been configured to act as a redundant array of independent disks (RAID) array.

RAID arrays write data across multiple disks as a way of storing data redundantly (to achieve drive failure tolerance) or to stripe data across multiple disks to get better performance than any one disk could provide on its own. Typically, a RAID array will appear to the operating system as a single disk, while a JBOD system would show you all the drives in the system independently.

The JBOD system doesn’t protect any of your data, so if a disk fails/dies then all the data written to it is lost, but since it is not a raid array the whole system would still be online and continue to act as if nothing has happened
