How's the weather on venus today?
Anyway, back on earth, cabin temp won't go over about 40C if you have overheat protection on- which you should given all the electronics in the car to start with.
Hence that Samsung drive with operating specs up to 60C is plenty fine no need to buy some stupidly more expensive spacecraft tech.
What Is Automotive Grade? Here's What It Means
it does not matter what YOU think your car's temp range should be, the people who design and build cars do know what they are doing, generally. nvidia's document says:
"That’s why our automotive solutions are rated to run from -40 to 105 degrees Celsius. It may seem like overkill, but the inside of a closed car can reach extreme temperatures during a sweltering summer day in many parts of the United States. And cars are sold in every corner of the world, Iceland to Israel, Greenland to Granada."
Likewise the % of tesla owners that'll see -40 is Pretty Damn Low.
as a design engineer (I work in automotive) you follow the guidelines for the industry.
you can ignore them, but then you've done less of a job if you think 'you know better' than the industry.
Why?
On a decently sized unit (128 or 256 GB) even non-endurance stuff is rated for enough write cycles to be good 5-10 years on the LOW end, and decades on the higher end. So why spend more money unless you think you're gonna need 40 year old dashcam footage, still on its original media, some day?
I don't have the same level of trust you seem to have for your flash media.
I've seen you claim this a few times- without ever offering any evidence, source, or explanation.
AFAIK the only thing reformatting will do to an otherwise working flash drive is waste write cycles and shorten the life of the drive. (Ditto the defragging you had previously been telling people to do frequently until I called you on that as useless for flash media)
What, specifically, is the technical explanation for why a "fresh" folder makes any difference in this application compared to a presently working existing one and can you provide any sources to support the claim?
simple, its a known fact that an initialized disk has no 'holes', no files taking up space that need to be skipped over, no fragmented allocations. re-formating (not low level format, but just 'mkfs' style format) does NOT wear the media down in any significant way. you are just init'ing the dir structures and partition table.
the test is easy to do; create a fragmented fat32 disk of any kind (copy files, delete some, copy more new ones, etc) and then compare the new file create time vs that of a freshly mkfs'd disk.
I'm not sure why you are fighting about this. this is already worked out, many years ago. defragging does definitely help with fat32 file creation (fat32 is not self-defragging, but ext4fs is). I would not suggest a sector by sector defrag, as that WILL copy data and create unnecessary wear. what I AM suggesting is that to freshen up the drive, you copy data from it to some new device (your home pc), then reformat the flash drive (quick format). since this is a teslacam drive, once you've copied the old files off, there's no good reason to put them back, so you have 3 choices:
1) leave the disk as-is and let tesla prune older files
2) copy data off and reformat
3) copy data off and delete older files once they're copied off
#1 leaves the disk fragmented and it causes more overhead for tesla to have to remove older files.
#2 is the best method, imho
#3 is not much better than #1, as the the disk is now fragmented and will get slower and slower over time
