Definitely high endurance. What matters is the amount of writes to the card, not over-writes. Most cash cams write to the card every 5min (in my case that’s about 300-500MB at a time).
The 64gb means the data is overwritten half as often as the 32gb, so it should last longer. If you use parking mode or drive a lot i'd get the 64, otherwise get the 32 this is an amazing price.
in my opinion, 32GB card is enough if you don't drive long distance every day. According to the site linked below, 32gb card will let you record 3~4 hours of footage in 1080p so that should be enough for most people.
I think you might be mistaken. Your dashcam might make 5min video files that are 300-500MB in size, but to hold that much in buffer and write it all out at once doesn't make sense, especially considering the write speed on these cards, it might take at best 15 seconds at 20MB/s writing 300MB.
Sorry, you are right: the card does get written to more than every 5 minutes. Silly of me to say otherwise.xtothel wrote: ↑ I think you might be mistaken.

A 64GB card will on paper outlast a 32GB card of the same family since there are about twice as many gates to rewrite (the storage circuit gets used half as much in the 64GB).
Depending on the type of storage used, the more durable type can last 3-7x longer than the cheaper/less durable type.
I'm using a 32GB Lexar that goes on sale around $10.00 on Amazon for over two years without any issues either.
I had problems with a Kingston one with Itronics.
