I'm absolutely not an expert on this, but you ideally provide a sufficiently large amount of storage area, with a flash memory controller, that over the expected (20 year plus hopefully!) lifespan of the product, the amount of periodic daily writes can be evenly distributed, and will not exceed the individual cell write lifespan.

Some people who have intentionally done torture test writes on consumer grade SSDs have discovered the actual cumulative TB writes that a $50 to $100 SSD will take before ultimate failure. From back in 2015: https://techreport.com/review/27909/the-ssd-endurance-experi...

One drive failed at 700TB written. If you were to write 2GB per day in an industrial/embedded application nonstop for 20 years, that is considerably less data than 700TB.

With teslas that have a persistent LTE data connection for the car, you also have the option of doing something like 300KB of file upload per day to a remote server.
