4. Close the cover and secure it with the screws removed in step 1
4 CONFIGURE THE RAID MODE
ATTENTION
: Setting or changing the RAID mode requires you to re-format the drives. This will erase all data
on the hard drives that are being formatted. Make sure to backup all existing data first!
RAID Description:
The following table shows the available RAID options and settings:
1. LARGE:
To be exact LARGE is not a real RAID mode, but could be seen as one. In LARGE Mode, the space of the second
disc is simply appended to the first disc. So the space of the two disks is added to one big disk.
2. RAID 1:
In RAID 1 mode all data is written identically on both discs. So if one disc fails the other contains all data again.
This provides security against the failure of one disk at the cost of the bigger disks space.
Notice: the RAID 1 mode is NOT a data backup! The thought behind RAID 1 is to have a system you can work
with even when 1 HDD fails!
3. RAID 0
RAID 0 writes data block wise alternating on the two disks. So two data blocks can be written at the same time
which enhances speed. The disk space of the combined volume is twice the smaller disk size.
4. SINGLE
Like LARGE it is not really a RAID mode. This means that both discs are integrated as separate hard drives with
its own content, independent from each other.
ATTENTION
: You have to choose a RAID mode as described. In default there is no RAID configuration and the
device shuts down within a few seconds.
