Can someone from Gemalto comment on the EGS5, etc. flash wear. The documentation suggests that using the flash extensively is not a good idea. However, can you tell us what operations should be most avoided. For instance, if I write to flash rarely but read often, is that OK?
Are there any wear levelling algorithms that we should be aware of?

Hi, as the module automatically manages FFS, the customer have only access to provided API. Please note that only unnecessary writing operation should be avoided. Gemalto doesn't provide specific writing cycles warranty. However, used flash memory chips have guarantee 100k write cycles. If you excessively perform flash write cycles you can kill the module already after short time. If you e.g. permanently power cycle the module every minute you can destroy the module after a few weeks as with every power cycle some non-volatile settings are written to flash.
Reading operation doesn't wear the flash down.
