Thecus N2200 User Manual

JBOD
Although a concatenation of disks (also called JBOD, or "Just a Bunch of Disks") is
not one of the numbered RAID levels, it is a popular method for combining multiple
physical disk drives into a single virtual one. As the name implies, disks are merely
concatenated together, end to beginning, so they appear to be a single large disk.
As the data on JBOD is not protected, one drive failure could result total data loss.
Stripe Size
The length of the data segments being written across multiple hard disks. Data is
written in stripes across the multiple hard disks of a RAID. Since multiple disks are
accessed at the same time, disk striping enhances performance. The stripes can
vary in size.
Disk Usage
When 2 disks are of the same size, and used in RAID, N2200 disk usage percentage
is listed below:
RAID Level Percentage
Used
RAID 0 100%
RAID 1 1/n x 100%
JBOD 100%
