RAID 1 VS RAID 0RAID
Capacity:

Safe Mode1

Master drive 4TB +Secondary drive 4TB = 4TB
Recommendation:
Use as System Drive orData Drive

RAID0Capacity:
4TB + 4TB = 8TB
Recommendation:
Use as Data Drive

Total Capacity 4TB

RAID 1 combines two hard drives into one hard drive; thesecondary drive is used as a mirror drive of the masterdrive. All the data written onto the master drive will also be
copied onto the secondary drive; therefore if the master
drive fails, there is a complete backup on the secondary
drive which is able to replace and work as the master drive
immediately. That’s why RAID 1 has the best data safety

Speed Mode

Total Capacity 8TB

RAID 0 combines two hard drives into a hard drive withdoubled capacity. When data is written onto it, the data will
be scattered onto the two drives; and when data is being
read, data will be acquired from the two drives
simultaneously. The advantage of RAID 0 is faster data
access, but its disadvantage is that it has no safety; once
one of the hard drives fails, all data on both hard drives will
be completely lost.

A failed hard disk can never let you down again.

warnings, it will use sound, E-mail, or SNMP to notify the user thatthe hard drive is starting to have bad sectors. Therefore, the user

instead of waiting until the hard drive is determined to have failed
before giving off the warning; this best guarantees data safety.
