JBOD – Concatenation
JBOD stands for “Just a Bunch of Disks” and normally refers to one or more
physical drives working independently. The AMD Chipset SATA Controller offers
the added feature of concatenation, where the capacity of multiple drives is
added together. When one drive is full, the data is saved to the next drive
automatically. By way of example, using this feature, three 500 GB physical
drives concatenated together have the equivalent capacity of single 1.5 TB drive.
Figure 6. JBOD concatenates the capacity of multiple drives
As independent physical drives, JBOD does not offer the performance or security
advantages of RAID logical drives. However, in RAIDXpert, you create, manage,
and delete a JBOD the same as a logical drive.
You can designate from 2 to 4 physical drives with online capacity expansion.
If you attach a single physical drive that was previously partitioned, RAIDXpert
will recognize it as a JBOD. However, RAIDXpert does not allow you to create a
single-drive JBOD.
