RAID 0 is a striped set without parity. This provides performance and additional storage without fault tolerance. The data is broken into fragments. The number of fragments is ruled by the number of disks in the array. This allows smaller sections of the entire chunk of data to be read off the drive in parallel to increase bandwidth.
JBOD stands for Just a Bunch of disks. This is the combination of multiple physical drives into a single virtual disk. It provides no data redundancy. We have the following presentation for JBOD drives.
Thank you for the information David.
The presentation is very clear. However I have another question after viewing the presentation
Disk 1: 300G
Disk 2: 300G
Disk 3: 300G
Configuring JBOD: Total logical drive is 900G
If my Data utilizes up to 500G, that means only Disk 1 and Disk 2 have data. In the event that Disk 3 will fail. Can we replace Disk 3 with another HDD or can we still use the JBOD with only Disk 1 and Disk 2?
