2.3.3.2.5 Calculating the expected service life for an existing application
To better verify whether an SLC or MLC CFast card should be used for an existing application, the following
procedure is recommended:
•
Read the "Average erase count" of the data storage medium via S.M.A.R.T.
•
Fully operate the system with the relevant data storage medium over a defined period of time (e.g. 1 week).
•
Determine the used erase cycles via "Average erase count".
•
Determine the expected service life based on the maximum guaranteed write/erase cycles (MLC: 3000,
SLC: 100,000).
