Adaptec RAID Configuration Utility
4
Create RAID via allows you to select between the different
creation methods for RAID 0 and RAID 1. The following table
gives examples of when each is appropriate.
Notes:
■
Before adding a new drive to an array, back up any data
contained on the new drive. Otherwise, all data will be lost.
■
If you stop the Build or Clear process on a RAID 1 from ACU
you can only restart it from Adaptec Storage Manager -
Browser Edition. (See
for details.)
■
A RAID 1 created using the Quick Init option may return
some data miscompares if you later run a consistency check.
This is normal and is not a cause for concern.
■
The ACU allows you to use drives of different sizes in a
RAID 1. During a build operation however, only the smaller
drive can be selected as the source or first drive.
■
When migrating from single volume to RAID 0, migrating
from a larger drive to a smaller drive is allowed. However
the destination drive must be at least half the capacity of the
source drive.

RAID 0
No Init
Creating a RAID 0 on new drives.
RAID 0

1 If you select Migrate for RAID 0, or Build for RAID 1, you will be asked to select the
source drive. The contents of the source drive will be preserved. However, the data
on the new drive will be lost.
Creating a RAID 0 from one new drive and
one drive with data you wish to preserve.
RAID 1
Build
1
Any time you wish to create a RAID 1, but
especially if you have data on one drive that
you wish to preserve.
RAID 1
Clear
Creating a RAID 1 on new drives, or when
you want to ensure that the array contains
no data after creation.
