If only one drive is installed, the RAID configuration will not be available.

Creating the RAID system will take several hours, depending on HDD capacity. Do not turn off the power or interrupt the system in any other way during this process! We recommend using the EXT2 file system for optimum performance and functionality. Changing the RAID setup will require you to re-format the drives. Make sure you backup all data before doing so!

There are 3 differents RAID mode:

∙RAID 0= RAID 0, known as disk striping, has generally the best performance, but does not offer any redundancy. In this level, data is broken into small units called sectors, and sectors are distributed across all disks in the array. As it does not provide any data protection, if any disk in the array fails then all data in the array is lost. Such stripes allocation allows to enhance I/O performance.

∙RAID 1= RAID Level 1, known as disk mirroring, is a popular approach to protect data from adisk failure. To implement RAID Level 1, you need at least two physical hard drives. As the disks are paired up, all disk writes are duplicated on both disks. You can back up data without interruption using this algorithm. In case of a disk failure, the system can continue to run without being affected.

∙JBOD=JBOD (Just a Bunch Of Disks) is a group of disks. JBOD is not technically RAID but “di spanning.” In this mode, together so they appears as a large single disk. Each
