1) it can take additional writes. This card can too since it also has storage space above 256gb, except unlike the 256gb card you can access the additional storage space from the get go, which is hugely important to increase the look-back period of your dashcam. 256gb is the current max storage for high endurance cards, if you want more storage you either have to periodically back up data to a hard drive or... you could just get the 400gb Ultra.
2) Some durability features. SD cards have zero moving parts, any condition that would destroy the Ultra would likely destroy the equipment containing it. There is only a narrow survivability delta, if any, where the high endurance would survive conditions that the ultra doesn't.
3) Warranty. The high endurance only offers 2 years warranty compared to 10 years on the ultra, but in the warranty terms the Ultra does not cover failures due to use in applications like dash cams. This is BS as all SD cards are already warranty-limited by write cycles. Write cycles are write cycles, regardless of whether they occur in a dash cam or a normal camera. Nevertheless this warranty is unnecessary as a) failures of legit microsds are extremely rare even in "high endurance" scenarios, and b) the costs of cashing in the warranty likely exceed the value of the replacement
In terms of compatibility, many pieces of equipment will claim to have a limit of say 128gb but take this card just fine.
In terms of write speed, a peak of 100MegaBytes/s is plenty for most consumer grade cameras. I've used it in an action camera and it can take sustained 4K 170 Megabits/s video (170 megabits = 20 MegaBytes) no problem.
TLDR/Bottom line: If you can afford it and if you plan on using the card in a scenario where you might possibly, at some point need maximum storage, this is the option that provides the best value.
SanDisk is one of, if not the biggest, SD card manufacturer and the quality of their products is the golden standard. So capacity, performance, and reliability goes without saying for these SD cards. However, I have read quite a lot of reviews claiming that the ones they received were imposters and, while I do not claim they are mistaken or not, I can say that my 400GB one I received from Amazon seems to check out through every test I've run it through.
Amazon has quality customer care and product replacement/return policies for the ginormous corporation they are, so if you have any issues with your product I'm sure you can get it worked out within reason. There are a lot of different resources for checking the validity of SD cards online and you can find them all with a simple search on a quality search engine website. If you are concerned, I suggest going that route or contacting local IT support to see what they can do for you.
PROS:
SanDisk. Enough said. Quality and performance.
CONS:
Obviously, verrry slim chance of the SD card being a fake. Technology is amazing these days and there are people out there driven to make a quick buck if they've got the materials and the know-how. Even giants like Amazon can fall victim to these numerous and unethical kinds of practices.
Happy with my purchase. 100% 400GB SanDisk SD card at a reasonable price.
Unfortunately earlier this year I got a memory card error while taking photos-- not only did I lost most photos I had just taken that day but random ones that were stored on the card. I'm not sure why this happened as I hadn't dropped the phone when it happened or even within the past few days, it suddenly just went out on me.
I've always trusted SanDisk and never had any issues, so unfortunately now I have to replace this but unable for the photos I took that cannot be replaced.

まだ使い始めですが、今の所大満足です。
Using it both in my Nintendo switch and switch lite with no issues!
I bought this micro SD to complement my new tablet laptop (HP Spectre). I’ve been using it for a few weeks now and it works really well - data transfer both ways is fast and best thing is, I can pop it in my micro SD slot and leave it there without having a lengthy or cumbersome USB (or 2TB hard drive) hanging off my otherwise ultra portable laptop.
Another reviewer commented this isn’t a genuine product. I bought mine direct from Amazon (ships from and sold by Amazon AU) and I can find no evidence that this isn’t genuine.
The price seems to fluctuate, but once it’s down again I will purchase another one as I’m so happy with this one!
