    I can't get them to send me the frickin' NDA. I've emailed several times to the guy that called me.

    I will say this about the BlackVue SD cards...They work!
    I've gone through 2 different SD card, the last one was the Samsung 128g. The Samsung lasted me about 2 months and then started messing up. My camera started giving the SD card message like every 20 minutes and then would randomly reset itself. I tried every method of re-formatting the card and nothing helped.

    I bit the bullet and bought the Blackvue 64g card and it's been trouble free ever since. The Dashcam store did warn me about getting a 128g card as they have a high failure rate. 64g cards are the highest memory that work reliably in the Blackvues.

    I've been using this one (Link: Samsung 128GB EVO microSDXC UHS-I/U3 Memory Card with Adapter, Speed Up to 100MB/s (MB-MP128GA/AM) - Newegg.com ) in my DRS750-2CH without issue since the end of February this year. Not a lot of time, only 4 months, but I have been happy so far. If it does fail, I'll be sure to comment on it. So far so good. I do not do any regular formats like some users do. I use the cloud feature to pull videos as needed, and have yet to encounter an unusable or corrupted video file. Using 1080p @ 60fps @ Extreme bitrate setting for front, and 1080p @ 30 fps @ Extreme bitrate setting for the rear. That results in roughly 180 MegaByte files per minute for the front and about 90 MegaByte files for the rear per minute.

    180+90 = 270MB/minute / 60 = 4.5MB/s.

    Dashcam cards need the best temperature and write endurance, not the best speeds.

    I didn’t buy it for the speed. I bought it because it met my requirements.

    • Operating temperatures of -25°C to 85°C, non-operating temperatures of -40°C to 85°C
    • 128GB
    • Not a "value" card.
    • No 128GB high-endurance cards were available for me to buy at the time. I didn't want BlackVue brand.

    I'm all for switching to a high endurance memory card, but want it to be 128GB or greater so long as it's supported with the BlackVue firmware.

    I can't seem to get people to understand this. Faster advertised rates are fine, but irrelevant. 15Mbps camera writes at less than 2MB/sec. Think about that. A dual channel camera at 15Mbps each is still less than 4MB/sec. Double each one at 30Mbps and you're still at less than 8MB/sec. Seriously.

    I agree. It's about endurance and capacity for me. I did the same math Jaguar did before I even went shopping. I knew the speed wasn't the issue for me. I was bringing up the data in relation to total storage for me. I get about between one to two days worth of saved content on my 128GB, depending on specific conditions. All in all, I have to keep on top of pulling content off if I want to make sure I don't lose it. I record motion, and capture every vehicle that drives by the busy road in front of where I park. That coupled with driving daily, I don't always have high retention rates with my configured settings, but I'm happy where it's at.

    Yeah, your case is unique because you want to keep them long term. Most of the time, if it's within the last 24 hours of my driving, I'll have the opportunity to stop and pull anything I need off. 32GB is plenty for my car, and 8GB is plenty for my wifes, because I'd only want to have proof of an accident for hers. -shrug-

    I'm currently using 128MB Samsung EVO Select cards in my two primary cams. They're U3 (100MB/sec), write speed capability totally wasted in this application. But they've been working well and hold plenty of drives including all the manually marked recordings until I remember to go ahead and pull them off.

    Pfft I've been running the same Sandisk Ultra 32gig in both mine and another one in my wife's car since 2014 and it hasn't failed me....and mind you my wife was in Phoenix at that time and I drove from ABQ NM to Phoenix on a biweekly basis so we got to experience the high desert dry/heat and phoenix/dry heat and now it's experiencing the East coast DMV area humidity and heat (for the past year) and it's still alive. SO both of them are working great. (watch it die within the next few minutes).

    edit: The Dashcam is hard mounted to the rear view mirror so it's in the sun/heat...although my wife used the sun reflector thingies you put on the windows when you leave the car...but still in Phoenix that doesn't mean ****.

    Still going in circles, got the design doc, still waiting to understand what 'moving forward' means to WDC so they'll send me the code/app examples.

    Got the app, apparently the 'supported' readers are SanDisk Extreme Pro SDDR-329 or SanDisk Extreme Pro SDDR-399

    Hmm. To invest more or nah...

    @Jaguar I spent some time looking through the PDF that you attached from SanDisk (tnsd02_enable_sd_health_monitor_system.pdf ). After reading it, I don't think that there is actually any additional code that SanDisk will provide you, beyond what is in that document. Essentially the document says "We believe in open source.... Take the source code found online for mmc_utils and modify it like so to be able to get the additional functions."

    Code:
    sudo git clone https://kernel.googlesource.com/pub/scm/ linux/kernel/git/cjb/
    
    That's the git command you'd type in a local *nix computer to clone the remote git repository (to get the mmc_utils project source code, and then in the PDF, numbered pages 3 through 6 contain instructions of what you need to add to the C code to get the additional functionality, before compiling the code.

    Then PDF page 7 it tells you how to use the program "mmc" after it has been compiled.

    I can't say for sure as I don't have one of these cards to test, but I think that is why they haven't responded and given you anything further... as I don't think there is anything further example wise for them to provide.

    HTH.

    I tried to send an email to "Jaguar is awesome" and it complained about not having a domain.

    :D
