Below is the comparison between 2 RAID levels:
RAID Level
Basic Operation
Method
Hard Disk
Available
Capacity
Data Reliability
Data Transfer
Speed
Minimum
Number of Hard
Disks
0
Striping data
across each
drive
Total capacity
of all the hard
disks
Low Highest 2
1 Mirroring
Half of total
capacity of all
the hard disks
High Lower 2
Linear : Spanning (Coming with maximum capacity, no data redundancy)
1) Only SL3620 support this mode.
2) Linear mode will sum up the volume of all hard drive. When the rst device reaches capacity, data is
sent to the next device in the group. But offers no real improvement in performance.
