Thanks for the heads up.Better to use Sandisk, not many users use Lexar, and some user report issue with Lexar before.

I think that answers why its much more cheaper than other major brand.Lexar are a known problem card, they're not the same quality they were three years ago
the price drop they did a few years ago was the signal as to when to avoid, were good cards before they sold their memory business offI think that answers why its much more cheaper than other major brand.
WD Purple is pretty cheap and it's rated for 24/7 surveillance purposes. (works perfectly fine in A129 Pro)
Are you saying that a 512GB card is less hardy than a card from the same manufacturer, but at 256GB?I do wonder how long it will last in the dash cam application since I have yet to see a high endurance version of a 512GB memory card.
Sometimes the high endurance 256GB version uses the same memory as the normal 512GB version. The difference is that only half the memory is visible and after a certain number of write cycles the well used memory gets swapped for fresh memory, thus giving the card twice the write cycle life. Of course the total number of writes is the same, but they can label one as high endurance. It is good for the manufacturers since if they make a 512GB and find that there are only 510GB actually working, they can then mark it as a high endurance version and it will have the full 256GB capacity and will last nearly twice as long as a normal 256GB.Are you saying that a 512GB card is less hardy than a card from the same manufacturer, but at 256GB?
I thought it was the other way around.
With the same mode of use, a 512GB card should work longer, since the rewriting cycles will be 2 times less than that of a 256GB card.
Thank you for the clarification and remark, you have planted doubts in me. It will be necessary to study the issue, since I have not ordered a 512GB card yet.
Thank you for opening my eyes. It will be necessary to think, maybe it will be easier to just buy a second 256GB card for long-distance trip.Sometimes the high endurance 256GB version uses the same memory as the normal 512GB version.

In reality it is not quite that simple, but you definitely shouldn't expect a 512GB to have twice the life of a 256GB, unless it is written in the specifications for capacity and write cycles. It is far more likely that when used in a dashcam, they will have the same life time.
This will be the best option.Thank you for opening my eyes. It will be necessary to think, maybe it will be easier to just buy a second 256GB card for long-distance trip.
It is good to have a spare in the car, but that doesn't need to be a high capacity spare.This will be the best option.
If one 256GB card fails, the second will remain working.
I use the second card not only as a spare.It is good to have a spare in the car, but that doesn't need to be a high capacity spare.
For some unusual events, I have a Bluetooth button on the steering wheel to block the file from being overwritten, so after not very long trips I can return to the event through the saved files and calmly analyze it. Just I had an event at the end of which I clicked "block", but a few seconds before that, the registrar completed the current three-minute block and started recording a new one. It turned out that I blocked a file where there was nothing interesting anymore, and the last block was overwritten, since the trip was long.Normally video from 200 miles ago is not of much use, but occasionally it may be.
I still don't want to think about filling out an SD card on long trips.It is not difficult to calculate the filling time of the memory card on long trips, when filling one card in the DVR,
