1.2 RAID Configurations Precautions
1. Please use two new drives if you are creating a RAID 0 (striping) array for performance. It is recommended
to use two SATA drives of the same size. If you use two drives of different sizes, the smaller capacity hard
disk will be the base storage size for each drive. For example, if one hard disk has an 80GB storage
capacity and the other hard disk has 60GB, the maximum storage capacity for the 80GB-drive becomes
60GB, and the total storage capacity for this RAID 0 set is 120GB.
2. You may use two new drives, or use an existing drive and a new drive to create a RAID 1 (mirroring) array
for data protection (the new drive must be of the same size or larger than the existing drive). If you use two
drives of different sizes, the smaller capacity hard disk will be the base storage size. For example, if one
hard disk has an 80GB storage capacity and the other hard disk has 60GB, the maximum storage capacity
for the RAID 1 set is 60GB.
3. Please verify the status of your hard disks before you set up your new RAID array.
WARNING!!
Please backup your data first before you create RAID functions. In the process you create RAID, the system will ask if you
want to “Clear Disk Data” or not. It is recommended to select “Yes”, and then your future data building will operate under a
clean environment.
