Cpu Drive - Campbell CR300 Series Product Manual

13.2.1 CPU drive

The serial flash memory CPU drive contains data logger programs and other files. This memory is
managed in File Control.
NOTE:
When writing to files under program control, take care to write infrequently to prevent
premature failure of serial flash memory. Internal chip manufacturers specify the flash
technology used in Campbell Scientific CPU: drives at about 100,000 write/erase cycles. While
Campbell Scientific's in-house testing has found the manufacturers' specifications to be very
conservative, it is prudent to note the risk associated with repeated file writes via program
control.
