Most of new SD cards use "wear leveling" that if your system will write to same place on the filesystem that controller in the card wrote data everytime to another place. For bigger lifetime it is a good idea to have Flash not full. Also it is a good idea to use "Industrial grade" SD card which use SLC chips instead MLC or TLC chips at normal flash cards and have much bigger number of writes to cells.
