you create, manage, and delete a JBOD the same as a logical drive. You can designate from two to four physical 

drives with online capacity expansion. If you attach a single physical drive that was previously partitioned, RAIDXpert 

will recognize it as a JBOD. However, RAIDXpert does not allow you to create a single-drive JBOD.     

 

RAID Ready arranges individual physical drives the same as if they were attached to the PC’s motherboard controller. 

The advantage is that the AMD 

SB750 Controller can accommodate up to four physical drives, more than most PC 

motherboards. As a single physical drive, RAID Ready does not offer the performance or security advantages of other 

RAID logical drives. However, you can create a backup drive by: Inserting an unformatted physical drive or 

designating an installed physical drive. In RAIDXpert, you create, manage, and delete a RAID Ready the same as a 

logical drive. A RAID Ready logical drive has only one physical drive. You can designate from one to four of your 

physical drives as RAID Ready.   

 

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. 

 

 

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. 

 

If you want to install Windows 

OS on a RAID disk composed of 2 or more SATA / SATAII HDDs with RAID functions, 

please follow below procedures according to the OS you install.
