About Flash Disks
ATA Flash disks are similar to linear Flash memory cards. Flash disks combine Flash memory
technology with a controller chip to achieve higher capacity and better performance than linear Flash
memory cards. The controller circuitry allows Flash disks to emulate hard disk capabilities, such as
automatically mapping out bad blocks and block erasure. Flash disks also provide the capability to
allocate noncontiguous sectors, eliminating the need for the squeeze command that is required for space
retrieval on linear Flash memory cards.
Flash disks look similar to older Cisco 20-MB linear Flash memory cards. You can install a flash disk
into either flash card slot on the PRP.
