D. Cache Policy
Two options are available when creating redundant RAID arrays (1, 5, 6, 10, 50).
1. Write Back
Provides higher write performance for redundant RAID arrays. Data is at risk when there is a power failure,
system kernel panic and/or the system is not responsive.
2. Write Through
Provides superior data protection when there is a power failure. Data is written directly to disk.
E. Block Size
Block sizes are adjustable from 16K through 1024K, default is 64K
F. Number of RAID5 member disks
This option is related to creating a RAID 50 array.
G. Select All
User can select how many disks to construct the array or click “select all” to use all HDDs for the array creation.
H. Capacity
This allows users to define how much disk capacity will be used. If “maximum” is chosen, the array will use all
available disk space.
