3. If you have two hard disks installed, select a disk configuration.
• JBOD (maximum data storage space)
Uses the whole storage capacity of each disk, even if there are
two hard disks with different storage capacities. With two hard
disks, you can create two volumes (one for each disk) so a
failure of one hard disk should not affect the other. With two hard
disks in a single JBOD volume, you lose all the data on both
disks if one disk fails.
• RAID 0 (not recommended)
Has the highest write speeds but if one disk fails, you lose all the
data on both disks. Only use RAID 0 for non-critical data
requiring high write speeds (like video, graphics, and games).
Total data storage space is limited to twice the capacity of the
smallest disk.
• RAID 1 (recommended)
Mirrors one disk’s data on the second disk for data security.
RAID 1 is slower than RAID 0, but you can recover all of your
data if a disk fails. Total data storage space is limited to the
capacity of the smallest disk.
