3. Hardware Requirements and Precautions
1. Only one interface connection may be used at once per computer system.
2. RAID volume formation utilizes the capacity of whichever hard drive has the smallest and then
multiply that capacity by three for RAID 5, four for RAID 0, to form a large volume, therefore,
it is recommended to only install hard drives of the same brand and specification for all drive
position prior to use. Moreover, when you need to replace with a new hard drive, please be sure
to purchase one with the same specification, capacity and brand. If these conditions can’t be met,
select one that’s at least 20 GB greater in capacity.
3. The actual storage capacity of SR4-SB3+ recognized by the system may differ from the total
capacity stated on the hard drives once the drives have been formatted.
4. When connected to the computer system, it’s prohibited to remove, insert or swap the hard drive
while data transfer is being performed.
5. It’s prohibited to change the positioning of the drives once the initial installation has been
completed as the changes made to the drive positions may destroy the RAID formation.
6. If you discover that hard drive failure is taking place, go to Section 6 “Replacement of
Malfunctioning Drive and Data Rebuild Instructions” and follow the steps accordingly.
7. Whenever turning off or unplugging the SR4-SB3+ from your computer system becomes
necessary, always remember to safely remove it from your operating system first.
8. In RAID 5 mode, the system allows one single hard drive failure. If multiple drive failures occur
at once, it’s likely that all data stored in the system have been destroyed or lost. In RAID 0
mode, if one hard drive failure occurs, then all data maybe destroyed or lost. If this happens, we
recommend you to consult with a professional hard drive data recovery specialist to see if your
data may be recoverable.
9. When the fan speed switch is set to "Auto", the fan will run at full speed to accelerate the heat
dissipation if the temperature inside the machine exceeds 50 (± 10%)°C.
