I put regular cards in my wyze and previous dashcams, they started failing within 1 yr.

I mean to each their own but I purchased the high endurance ones and no issues past 2 yrs now with my Yi dashcam

I have been using a standard Sandisk card for a while now which isn't High Endurance and have had zero issues with it. Probably been using it for 2 years now. Im sure at one point it might have some issues but the price of SD cards keep dropping I have plenty of backups. Just pray it doesn't have an error when you actually need the video in an accident or something.

That's the most important part. Don't want any issues when I need them

If for any reason you want to file a warranty claim, it automatically voids the warranty and SanDisk won't honour it because these microSD cards aren't meant to be used for dashcams. That's why there are High Endurance ones which are specifically made for dashcams, security video, etc.

I've read this one is the best: Transcend 32GB MicroSDHC Class 10 UHS-1 Memory Card with Adapter up to 60MB/s (TS32GUSDU1PE)

Sandisk Ultra = TLC = bad for continuous writing... thanks for that tip!

No, especially not for a dashcam. "High Endurance" cards are mostly marketing. YES, they last longer, but non "high endurance" cards will last most people using them in dashcams for many years.

For example:
https://www.amazon.com/SanDisk-Enduranc ... B00V5Q1K3O

Lists:
Up to 10,000 hours of Full HD video recording
&
Based on Full HD (1920x1080) video content recorded at 26 Mbps to one device;

So, a little math, that's:
10000 hours * 60 * 60 = 36,000,000 seconds @ 26Mbps ~= 117 TB

Wow, that sounds fantastic, for the 64GB card that's a full 1800 full writes to the card, WOW!

But, let's stop for a second and look at that 10,000 hour figure.

Say you drive 3 hours a day (alot for most people), 5 days a week = 15 hours/week * 52 weeks/year = 780 hours/year

So, to use 10000 hours of recording: 10,000/780 = 13 years

Frankly, if you still have the same car in 13 years I'd be surprised, if you are still using the same dash cam and SD card in 13 years? Not a chance.

Let's look at a 'typical' SD card endurance.

I've done some quick searching on write endurance, focusing on TLC, the figures vary, from as low as 500:
https://media.kingston.com/pdfs/MKF_283 ... ide_EN.pdf
To something around 3000-5000:
https://www.mydigitaldiscount.com/every ... flash.html

I'll go with the worst I could find, the 500.

That means your typical SD Card will withstand 500 write cycles, that's less then a third of the 'high endurance' card. But in a dash cam? That means instead of 13 years your run of the mill SD Card, WORST CASE, will 'only' last 4 years.

Note that I'm making several assumptions that err on the side of 'worst case', I've set a rather high commute time (3 hours/day is above average), chosen the worst cell type and write endurance type I could find (TLC and 500 cycles).

If you are running something 24/7 then PERHAPS a high endurance card will come into play, but even then, you can mitigate the cell write cycles by just getting a bigger card, a 128GB card will last 4 times as long as a 32GB card, I'd rather put the extra money into more storage space.

Do you have actual experience with that? I've had two sandisk cards fail, both in dash cams, both non 'high endurance', and both cards were replaced under warranty without issue.

In both cases the cards were unreadable (wouldn't show up in explorer when you put it into a computer), this seems a 'normal' failure mode for at least that kind of card. So how would SanDisk even know what you'd been writing to the card if it's completely dead?

You had crap cards. Doesn't matter who the manufacturer was, all of them produce some crap cards from time to time.

My card failures have ranged from top of the line Sandisk, to no name whatever. Some have failed in 'high endurance' situations, some have failed in my DSLR, some have failed seemingly sitting in a drawer.

The point is your observation doesn't prove anything. A sample of two is not representative of anything IMHO.

EVERY card you buy can fail, don't for a second believe buying a certain type of card protects you from that.

If you REALLY want to be sure, have two dashcams, with completely different cards in them, that'll increase your chances.

Depends on what you want, most people only care about storing there last couple drives, anything before that probably isn't needed. I find 32GB is more then enough, going bigger reduces the cycling on the card, so that's a good thing, but not necessary.
