As I mentioned earlier, 18+ months of perfect operation on the Samsung Fit Plus recommended in the manual (I have the 128GB one)
Some folks will insist you need a high endurance SDcard... you don't. For one thing the car doesn't write nearly as much data as those cards are really needed for- for another it then adds another point of failure (a USB to SD adapter) and a number of folks have had those fail on them too.
Some will insist you need an SSD... you don't. The operating temp range is generally narrower than either keys or sdcards (sometimes narrow enough even cabin overheat protection might not be sufficient), cost is several times higher, and with the car writing only a small amount of data, at very low speeds, on a USB 2.0 port, you get no advantages from the higher performance of the SSD either. Plus it's physically larger and draws 5-10x more power too.
TONS of threads where all the points above have been argued of course- and I suspect we'll get another one here shortly.
But that's my advice based on all the actual data and specs known- and what Tesla themselves recommend in the owners manual.
