What is jbod raid mode

The drives in a JBOD enclosure can function as individual units, undergo disk spanning to act as one unit or be configured to act as a RAID with the right host system technology. When functioning as one unit, JBOD uses a process called spanning. When one disk drive in the enclosure reaches its capacity, data is stored on the next drive in the enclosure, and so on throughout the entire unit.

Data is not fragmented, duplicated or combined as with RAID. The various RAID levels use a variety of storage processes to achieve data redundancy and fault tolerance, including striping, mirroring, a combination of striping and mirroring, parity and double parity.

For example, RAID 0 uses striping only, which fragments data onto the drives in the array and offers no data redundancy, while RAID 1 uses mirroring only, which duplicates data onto the drives and offers data redundancy, albeit a less than outstanding degree of fault tolerance. Note the 24 individual NVME solid-state drives. This JBOD is perfect for programs and applications that need tons of storage and super fast read and write speeds. JBOD enclosures and most RAID levels allow for hot swapping, meaning a drive in the enclosure or array can be replaced without shutting down the host system.

Of course, based on all the above statements, JBOD will be much cheaper. In addition to the fact that you can use the simplest and cheapest hard drives, the choice of controllers is also much larger. RAID can be either expensive or very expensive, but its benefits in terms of performance, redundancy and more are worth it. The application does an excellent job of recovering any kind of data, while automatically determining the desired type and size or array, as well as the order of the disks.

You can store files on another hard drive or partition, use virtual disks, or even upload files via FTP. The ability to create a disk image may be a pleasant surprise for you, especially since this is done for free.

In addition, there is a free preview and a recovery wizard for beginners and amateurs. The licensed version of the application is always available. I recommend reading the article in full if you want more detail. Today, however, JBOD is becoming increasingly popular as storage becomes larger and more intricate. And then, the striped disk sets are mirrored. It is usually called "a mirror of stripes".

Under this RAID Mode, it provides another way to achieve higher performance and data security, while increasing complexity. The array can sustain multiple drive losses as long as none of the mirror set loses all of its drives.

In JBOD, the number of logical drives is equal to the number of physical drives. This mode allows the RAID System to operate as a multi-disk storage enclosure, but provides no data redundancy.

HotSpare When any of the disks in the system fails, the back up disk will automatically be rebuilt to replace the failure disk.
