Q&As
GENERAL
Q: How do I choose the proper RAID mode for my RAID Unit based on the tasks
I need to perform?
A: Since the RAID Unit is a “Mass Storage” device, which means its size
capacity is sufficient for data management, the different RAID mode settings can
help you administer the enormous data storage from the HDDs combination. It is
highly recommended to choose the RAID mode based on what is the essential
factor to complete your task. The most common three factors are size capacity,
speed, and data protection. For example, if using the RAID Unit to simply watch
films for enjoyment or for storage, the JBOD and SPAN modes are perfect
because they can maintain decent speed and still have a large storage capacity.
If the work requires instant and continuous backup of data such as for a writer or
editor, then RAID 1 would be the best choice. However, if immediate data
access is required such as business professionals, RAID 0 would be more
appropriate.
DAISY CHAIN
Q: Because there are two (2) FireWire ports on the RAID Unit, I connected them
to my other two (2) external devices. Why can’t I see these additional external
devices on my host? I’m using the USB connection from the RAID Unit to my
host.
A: In order for the “Daisy Chain” feature to work properly on the RAID Unit, one
of the FireWire ports need to be connected to the host, and the other one can be
connected to an external device. The computer will not recognize different
interfaces if they are all used at the same time.
OLD HDDs
Q: My old hard disk(s) have data inside. Will the stored data still be recognizable
if I just install them into the RAID Unit?
A: Please backup all existing data from the old hard disk(s) before installing them
into the RAID Unit. Once the old hard disk(s) are inserted and setup for a
chosen RAID mode, the RAID MASTER will automatically re-format the disks
and all the old data will be lost.
HDD SIZE
Q: Can I use one 2.5” 9.5mm thick SATA HDD, and one 2.5”12.5mm thick SATA
HDD inside the same RAID Unit? Will the RAID Unit be able to recognize them?
A: Yes, the RAID Unit can support both 9.5mm and 12.5mm thick 2.5” HDDs.
