So what are some of the 128GB cards that are recommended? I search on Amazon for High Endurance, results are very limited.
Are they somehow limited to 64GB?
I can't make a specific recommendation for this camera because I haven't received it yet, much less tested it.
That being said, there are very few "high-endurance" cards larger than 64GB, and even fewer that use SLC. I suspect that's mainly a matter of low demand due to high cost. Dash cams are a relatively small piece of the total market for high-capacity SD cards; and in most other applications, high-quality MLC cards will last "forever," for all practical purposes. In terms of rewriting, there are very few uses for an SD card that even come close to the rewrite demands of a dash cam. MLC is more than adequate for almost any other application.
To further complicate matters, rewritability isn't the only thing to consider when selecting a card for dash cam use. Physical durability is also an important consideration. A dash cam is an extreme environment in terms of heat, cold, condensation, and vibration.
I'll initially be using a Samsung EVO Select 128 card for my second card. The dash cam comes with a 128 card, although I don't know the manufacturer or type yet. I'll be using the Samsung EVO Select card simply because I already have an unused one and because I've never had a problem with that model card in any other device. It's a TLC card made specifically for the Amazon market. It's identical to the EVO+. The warranty does
not cover dash cam use. But I already have one. If it works, great. If not, no big deal.
If I were ordering a card specifically for the dash cam, however, I'd limit my search to "Industrial" and "Pro" cards. Industrial cards are commonly used in embedded applications where they can't be easily changed, so they're designed to higher endurance and durability standards; and many of the "Pro" cards from well-known manufacturers also meet those standards. In some cases they're the same cards with different labels.
Finally, one has to consider manufacturer reputation. Just because a manufacturer
says that a card meets a certain standard doesn't mean it actually does. If they fudge the numbers, chances are that no one will find out for years. In industrial applications, I've found Samsung, Panasonic, and Kingston cards to perform as promised or better. Sandisk cards have performed well at the higher end, but not the lower end, of their model line, in my own experience. Adata and Transcend have generally been disappointing in terms of living up to promises, again solely in my own experience.
