RAID Mode
The enclosure can be set to function in one of four modes; Normal, JBOD, RAID 0, and RAID 1, giving you the flexibility to access your data in whatever way works best for you. The available modes are described below, with their corresponding dip switch setting displayed on the left side of the image.
Normal Mode – This mode treats both hard drives as separate disks, allowing them to be accessed independently of each other. Your computer will recognize them as if they were flash drives being plugged into separate USB ports, not changing them in any way.

JBOD Mode – This mode combines the two hard drives into one large drive for the purpose of increased storage space. Data is stored on one drive at a time, so when the first one is full, the next one begins to be used. The computer’s operating system will recognize them as a single drive.

SATA1 1000G | SATA2 750G | 1000G+750G=1750G |
RAID 0 Mode – This mode combines the two hard drives into one large drive for the dual purpose of increased storage space and performance. In this mode, data is split amongst the two drives simultaneously, improving the read/write performance. The risk in using this mode is that failure of one disk will result in total data loss. When using this mode, it is recommended that you use hard drives with the same capacities. If hard drives of different capacities are used, the smaller hard drive will be doubled in size, with the remaining space on the larger hard drive going unused.
