RAID 1+0 requires a minimum of 4 drives in an array. If one of the drives
defects, the identical backup data is available offhand.
JBOD (None RAID)
Just a Bunch of Disks (JBOD) or None RAID refer to a group of hard 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.
Under the RAID MASTER, JBOD Mode is not listed as an option and the
hard drives can be operated as JBOD simply in its original “unreleased” format.
HOT SWAP
Hard Drive Hot Swap refers to the ability to add or remove a device from the host
computer without powering off the device; the system will automatically
recognizes the change after the Hot Swapping is completed.
Under Striping, Span and JBOD modes, it is not recommended to perform
Hot Swapping when the hard drive is transferring data. Any attempt to do so
may result in complete loss of all data.
Under RAID 1, Clone, RAID 5, or RAID 1+0, any attempt of Hot Swapping
may terminate the data transfer when using the USB 2.0 connection. Please
resume the data transfer without Hot Swapping.
