NST-225MX-S3        2.5” Dual SATA 6 Gb/s to USB 3.0 HDD/SSD RAID 

 

10 

 
RAID 1 (Mirror): 

It allows the device to automatically copy data to both HDDs. It stores 

all data in duplication to both drives to protect against data loss out of drive failure. 

 

If one drive fails, the Mirrored volume is still usable, but it is in a vulnerable state since 
the other mirrored hard drive is inaccessible. When the offline drive resumes online, the 
appliance begins the rebuild process immediately to restore data redundancy.   
Host access takes precedence in rebuild process. If you continue using the Mirror volume 
during the rebuild, the rebuild process will take a longer time to complete, and the host 
data transfer performance will also be impacted. 

 

 

JBOD (BIG or LARGE): 

It concatenates a series of physical HDDs as a single large 

volume; HDD 1 and 2 are combined into a storage capacity that is equal to the sum of 
both HDDs.
