I’m developing a prototype to record energy data and writing data to SD card every second(or even lesser time period) which is coming from my multi parameter energy sensor. suppose to keep this up and running this for longer period(Max 1 months)
Is this bad for the SD card? Any Idea about the life span of the SD card.
You will never damage an SD card with an Arduino. The card controller does wear leveling by remapping physical flash blocks to logical block addresses.
Even if you only write one logical block address, the result will be to write all physical blocks.
SD Cards have an endurance specification for each physical sector of 100,000 writes typically. This means you can write 100,000 times the capacity of the card.
So don't worry unless you plan on writing a 100 Terabytes.
