Q&As
GENERAL
Q:
How do I choose the proper RAID mode for my RAID System based on the
tasks I need to perform?
A:
Since the RAID System 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 hard drives 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 System to
simply watch films for enjoyment, the RAID 0 mode is perfect because it can
maintain decent speed and still have a large storage capacity. However, if the
work requires you to process large files and to have a high volume of data
access such as for a graphic designer or film editor, it’ll be more efficient to
choose RAID 5 or RAID 5+HotSpare modes. Both modes provide the ability to
do hard drive hot-swap without affecting the data itself, and have a higher data
protection level. Lastly, if the work requires instant and continuous backup of
data such as for a writer or editor, then RAID 1+0 would be the best choice since
it can provide both high data protection and speed with less storage capacity.
HARD DRIVE CAPACITY
Q:
All my hard drives are at least 1TB or above, will the RAID System be able to
support the gigantic storage capacity?
A:
Yes, the RAID System will be able to support any hard drives over 1TB size
capacity. However, most older host systems cannot support over 2TB of total
capacity, only Mac OS 10.3 and newer, and PC Windows Vista or newer. In
addition, based on the host system you have, there may be limitations on the port
connections when the storage size is over 2TB. Please see the chart below.
