Most relevant excerpt from the 2nd linked article:
There are several types of SD memory cards, the most common ones being TLC (Triple Level Cell) and MLC (Multi Level Cell). Basically, SD cards employ flash memory, which in turn is made up of cells. In TLC cards, each cell stores 3 bits, whereas in MLC cards, each cell can hold only 2 bits. ----LINE BREAK----Now TLC cards are cheaper to produce, which is why they are the most popular, but they also have a considerably lower lifespan. TLC cards typically endure 3,000 to 5,000 write cycles per cell, while MLC cards last for around 10,000 cycles.----LINE BREAK----There are other types of flash memory as well, such as SLC (Single Level Cell), with just one bit per cell. SLC is even more expensive though, and often only available in small capacities. SLC is typically used in industrial environments and for heavy-load servers.----LINE BREAK----For use in dash cams and other video surveillance cameras, High Endurance SD cards are ideal. These usually employ MLC technology. There’s more to it, such as the controller on the card that makes sure that all the cells are used evenly, but we don’t want to become too technical here as the article would become too long."
