7 Modifying Your Storage Space
This section provides additional scenarios for creating and modifying arrays and logical drives. It explains how to check your logical drives for bad or inconsistent data; optimize controller and logical drive performance; move arrays and logical drives; and perform advanced operations, such as creating a split mirror backup array.
7.2 Creating and Modifying Logical Drives
7.2.1 Including Different-sized Disk Drives in a Logical Drive

7.2.1 Including Different-sized Disk Drives in a Logical Drive

You can combine disk drives of different sizes in the same logical drive. If the logical drive includes redundancy, however, the size of each segment can be no larger than the size of the smallest disk drive. (See Selecting the Best RAID Level for more information about redundancy.)

Note: You cannot combine SAS and SATA disk drives and also different block size like 512 bytes or 4K within the same array or logical drive.

To create a logical drive with disk drives of different sizes, follow the instructions in 5.4.1 Creating a Logical Drive on a New Array. When the wizard displays the RAID Members panel, select different size drives, as shown in the figure below, then complete the wizard.

When the logical drive is created, check its resources on the Storage Dashboard: it should appear similar to the next figure, where a RAID 5 logical drive includes two disk drives of one size and one of another.
