However, if the disk contains part of a large file located in that same volume but on another disk, that file will become unreadable. If one disk fails in a multi-disk JBOD setup, only the data on that disk will be lost.

JBOD – JBOD (Just a Bunch of Disks) pools all of your disks into 1 giant volume but still treats them as separate disks.

However, it’s possible to delete the configuration files of 1 drive and cause the array to fail. If 1 drive out of a 3-drive RAID 1 array fails, the array itself will continue to work AND your data will be safe. So if 1 drive out of a 2-drive RAID 1 array fails, you still have a copy of your data.

RAID 1 – RAID 1 (or “mirroring”) creates copies of the drives in the array.

But this means that if one drive fails, all of your data or even the array becomes unreadable. This allows the RAID array to perform faster because it can read/write data from multiple disks (even if it appears as a single volume). RAID 0 – RAID 0 (or “striping”) combines 2 or more disks into 1 volume and distributes data blocks evenly among them.These are also the RAID levels that we will primarily be working with for this article.
