readonly sd card, how to extend sd card life?

[Daniel]

Hello,

Two weeks ago i had a HL 1.5.1 with a readonly sd card -> update error, trend logs gone etc etc

Last weekend a LM (latest firmware) with a readonly sd card -> scripts gone after reboot etc etc

Both device < 3 year operation.
Both devices +- 10 trend logs.

How to extend the sd card life to prevent such failures?

Hi

The card used in the controller is standard MLC card and sometimes such things can happen.  Our records show 0.4% of failures which is not so bad but not good ether.  If you looking for good quality card then you should replace current one with an SLC one. You are looking to spend 50euro on such card.

The good news is that we decided to improve this situation go get to 0% level.  Some times next year we will release new hardware version with SPI flash build on the cpu board. SD card then will act as additional storage but all system will be saved on this industrial flash.

Sorry for the inconvenience.
