Product Description

Product Description
CompactFlash Disks are designed with Flash technology, a nonvolatile storage solution that does not
require a battery to retain data indefinitely. CompactFlash Disks provide complete PCMCIA-ATA
functionality and compatibility as defined by the CompactFlash Association in their CF+ and
CompactFlash Specification, revision 1.4.
The CompactFlash Disk is more flexible than linear Flash memory because the CompactFlash Disk has
controller circuitry that allows it to emulate a hard disk and automatically maps out bad blocks and
performs automatic block erasure. Further, the CompactFlash Disk provides the capability to allocate
noncontiguous sectors, which eliminates the need for the squeeze command (previously required with
linear Flash memory cards).
The CompactFlash Disk provides increased Flash-based memory space—64 MB to 128 MB—for
storage of system configuration files, Cisco IOS software images, and other types of system-related files.
