Have you read sandisk’s warranty page? They do not support dash cams or security systems with the usb sticks, the higher end ones that i bought
Because they often have 5 year warranties, and as I mentioned- if your application is multiple high bitrate 4k cams run 24/7, you're gonna run through the rated lifetime of the drive faster than that.
But you're not doing that here
You're recording some ~30 fps 720p cameras- and probably not 24/7 either.
. The heat produced and the protrusion is also a negative. The SD cards with the usb SD card adapter works way better in regards to not failing.

Math or no math, I’m speaking from personal experience with two different cars.
Ok, and many others are speaking from personal experience who HAVE had SDcard adapter failures. Many more are speaking from personal experience with USB keys who've had 0 issues.
With hundreds of thousands of teslas on the road running dashcam today, a sample size of "two cars" isn't really useful though.
There's plenty of folks who've had failures with both (most commonly with the USB to SDcard adpater for the SDcard)- and also with SSDs (lots of reports of issues there with the last update or two)
There's also plenty of folks who've been using both, with no issues, for a year and a half now since the feature launched.
Tesla themselves explicitly recommends two specific USB keys in the owners manual.... and I'd be willing to bet keys are what the majority of owners use- because it's the most common thing, specifically suggested in the manual, and doesn't require any adapters or extra HW.
Take it with a grain of salt if you wish, but definitely read the sandisk warranty page for their sticks.
Already covered why that's so- and why it's not relevant to the discussion here.
Did you know they don't cover dashcam use on some of their sdcards either?

Sandisk SD card warranty said:This warranty does not cover use of the Product in connection with the following uses or devices (as determined by SanDisk): (i) normal wear and tear, (ii) video monitoring, security, and surveillance devices, (iii) internet protocol/network cameras, (iv) in-car recording devices/dashboard cameras/black box cameras, (v) display devices that loop video, (vi) continuous recording set top box devices, (vii) continuous data logging devices like servers, or (viii) other excessive uses that exceed normal use in accordance with published instructions.
That's the page you get linked to if you actually read the fine print on some of the SDcard warranties

(see footnote 6)
Again, this has nothing to do with the form factor.
SDcards and USB flash keys are both using flash memory
Same basic technology.
It's about the rated # of write cycles for the type of flash they are using.
You can get USB keys with higher rated flash than some SDcards. And vice versa. And you can get both in quality keys or cards with flash that, as I mentioned previously, will be good for at least 5-10 years of Tesla dashcam use in either form factor.
So to me you're better off just buying a quality USB key, rather than needing a quality SDcard AND quality adapter, and doubling the # of points of failure. See again there's many posts about such failures despite your massive experience on TWO whole cars
