Caution
The life of a file system based on flash memory technology is primarily determined
by the number of write or deletion operations performed on it. Obviously such a file
system is not suited to highly cyclic write or delete operations.
The file system of the CP 243-1 IT uses an internal optimization routine to assign
all available locations of the flash memory uniformly. When individual memory loca-
tions fail due to old age, these locations are detected and marked internally as un-
usable. Despite this, highly cyclic write or delete accesses to the file system of the
CP 243-1 IT should be avoided.
