RAID Settings Descriptions 

 

 
SINGLE MODE 

Array will show up as two independent drives. This function 

can be used if only if two different brands and/or capacities 
of HDDs (Hard Disk Drives) are installed. 

 
 

Two HDDs will show up as a single drive with the combined 
capacity of both drives. Spanning writes data sequentially 
across two drives.  

 
 

Two HDDs will show up as a single drive with the combined 
capacity of both drives. Speed and performance increase. 

The two HDDs “stripe" data across the two drives. This splits 
each piece of Data across both HDDs in segments in a way 

that speeds up reading and writing times. However, RAID 0 
does not offer any data protection: if one drive fails or is 
damaged, all data can be lost.  

 
 

The RAID controller creates an extra copy (or mirror) of data 
on the two drives. Only a single drive will show up on your 

computer, and it will have the capacity of a single drive.   
 

Data is protected from the failure of one drive. If one drive 
fails, replace it with an identical drive and the data rebuilds 
automatically.  

 
Using this mode requires 2 identical HDDs; the two drives 

must be the same capacity, brand and model number.
