I personally would not trust any valuable data to a thumb drive. Nor would I trust them for a purpose like this.[/QUPTE]
Why?
We've been over the math. The car writes very little data relative to the rated life of even just "decent" USB keys.
And millions of people use micro sdcards their phones, dashcams, and digital camcorders. They withstand high temp ranges and the rigors of high read/write cycles.
Mostly they're used for those purposes for 2 reasons-
1) In applications writing [B}massively more[/B] data over device lifetime, it's easier to find high endurance in SD... (though you CAN find it in keys too)- this is not relevant to the Tesla where even a decent USB key will be good for 5-10 years at minimum (again math previously given).
2) An even bigger reason for most applications- because they're physically a ton smaller
Can you imagine having to have a USB key sticking out the bottom of your phone all the time?
Flash is flash. You can buy a USB key and an SDcard with the same quality/type of flash memory. You can buy one of each where EITHER is better quality/type of flash if you want.
There's no functional difference inherent in key vs card- just physical form factor.
Likewise you can buy SSDs with crappier flash than some USB keys or SDcards- and vice versa.
I'd way rather trust a TLC-based USB key over a QLC based SSD for example.
