Note: The options available under the disks drop-down menu changes
depending on the flash type. Some flash types only have one option
for the number of disk volumes, others have two options.
6. For each disk volume, determine the Read/Write access option.
7. The Script File Path displays the path of the selected script file.
8. Select a Cushion percentage from the Cushion drop-down menu to specify the
percent of flash reserved for cushion. Choosing a higher number reduces disk
storage space, but also increases write performance on fragmented disks or disks
becoming full. To speed the writing process, select as high a number as your
storage needs permit (up to 25%).
