Have Sandisk High Endurance cards in several version from 32GB to 256GB and like every one of them. And what a fantastic deal for the cost! $46 CDN for a 256GB card on Amazon. I use them for dash cams, and regular camera use, and have never had any issues whatsoever. And they are fast. Even the 32GB is U3 rated and speed rated at 100 MB/s read and 40 MB/s write. Cant say enough good things about my experience with Sandisk High Endurance micro SD cards.
If you only want the 32GB version, especially for dash cam or continual recording use, you may consider the Sandisk Maximum Endurance version for a couple extra bucks. Currently the 256GB version of the Sandisk Maximum is not cost effective in my opinion (double the cost of the high endurance version).

I know that published specs are maximum values but this card claims 100MB/s read and 40MB/s write. I tested it in a Lexar USB 3 card reader and in the card slot of my iMac and only got 20 MB/s for both read and write. My other cards read at spec in this reader. My Dashcam records at 30MB/s so I was concerned about skipped frames and sure enough in a 5 min clip I do see missed frames. I would return it but I had to pretty much destroy the packaging in order to get the card out. I should have gone for the more expensive Samsung High Endurance.

Finally I found a 128 gb micro-sd card works on my stupid dash cam. A dash cam reset sso often to be compare with an original card from thinkware however the price is fractions cheaper so it’s acceptable. Not sure how long it will last for. ***Update on November 19: Not fully compatible with my thinkware dashcam. Tried to format the card many time in both fat 32 and exfat. Anytime I get in the car to start my ride, it always been noticed that the memory card need to be formatted.

Highly recommend to test with h2testw right after opening the packaging. You could receive a defective product or a counterfeit one. h2testw is a free tool that simply writes data into the card and reads it back. In my case it failed this simple test. I bought this for my dashcam and it’s quite important that this is actually reliable. If it doesn’t work what’s the point of having a dashcam? Please also note that I haven’t encountered a single dashcam that can detect read/write errors and inform the user. It just chugs along as if nothing is wrong until you actually get into an accident and find out that it’s stopped working back in 2015. It’s just the nature of the beast. To ensure no surprises I would recommend testing it every month by simply playing back something even if it’s yesterday’s recording. I’ll be using Samsung Pro Endurance cards from now on. Never had any issues with that despite using one for the past 2 years.

I bought two 128GB High endurance cards for my dash-cams from this seller, looks like they are genuine SanDisk cards.
I tested them by using different softwares, screen shots are included Read/Write speeds are like advertised .
This is very important, if you don’t have fast micro SDCard reader every test will come back with Read/Write speed below 20mb/s or whatever the speed your SD card reader has. With slow SD Card reader basically you are testing SD Card reader speed not a actual SD Card speed.
Most of the SD Card readers especially old ones are slow so it makes so sense using them for testing SdCards because you will always think that Micro SD Card is slow or fake when in reality it’s your SDC ard reader Read/Wriet speed that you are getting not actual SD Card speed.
SD Card reader used during this tests was ( Verbatim USB-C Pocket Card Reader ) I recommend this one it’s affordable small, and fast.
I bought this for my new Nextbase 322GW dash cam with rear-view module – these require a quick U3/V30 memory card to ensure good quality simultaneous front and rear continuous recording. A ‘High Endurance’ card is recommended to meet the harsh conditions inside a car and constant rewriting to the card whilst driving.
This card claims to meet the Nextbase requirements. So, I did a quick check with CrystalBenchMark and the device proved to be marginally slower than advertised (88/38 Mbps). However, it works well in my dash cam with both cameras running and I have no complaints about the integrity or quality of the recordings.
Nextbase suggest that SD cards are reformatted in situ about once month. I presume this tidies up the file system and checks the integrity of the card.
The card is advertised as ‘High Endurance’ so time will tell as to how well it stands up to the harsh dash cam environment. After 1 month of continuous use it is still working fine. Fingers crossed! UPDATE. All continues to work well – indeed, I have just purchased the 128GB card for the wife’s new dash cam.

I tried to write a 32gb image to a 32gb card, something I’ve done with other cards for using in raspberryPis I tried 3 times and it failed every time around the 9GB mark.
Hard to believe anyone would go to the effort of conterfeiting a 32GB sd card these days, but mine had different looking packaging to the others as well. So I’m not sure if it was real.

I purchased a new card reader that supports USB 3.0, and now I’m successfully getting 90MB/s read and 80MB/s write speeds. It still doesn’t make sense to me that a lower-tier SanDisk card performed better than this one did in that particular SanDisk card reader, but using a Kingston USB 3.0 reader, I’m getting double the advertised write speed.
I am leaving the original review below as a cautionary tail about assuming that the average card reader is up to the task of handling these kinds of speeds.
Beware that if you have poor performance while using this card, your card reader probably can’t match the speeds of a high-performance microSDXC card.
———————————————————————————— ***IT TURNS OUT THE CARD READER WAS TO BLAME*** ***IGNORE EVERYTHING BELOW THIS LINE***
I put this through a stress test and ended up with speeds that are significantly lower than advertised.
The stress test was done using the `stressdisk` utility. It consisted of writing approximately 1000 identical files each consisting of 250MB of random data, followed by reading random pairs of those files to ensure that they all actually were identical. In total, over 250GB of data was written and over 850GB of data was read. The test passed with zero errors, but the overall read and write speeds were extremely poor.
The average write speed after the full data write was 18MB/s, and the average read speed was 14MB/s.
I suspected that the slow speeds could be a result of writing many relatively small files and then reading two back at the same time. To test this theory, I reformatted the disk and used stressdisk to write a single 5GB file, then read the file back. I ended up with a 17MB/s read speed and a 14MB/s write speed.
For comparison, I have an older model SanDisk 32GB High Endurance microSDHC card, and using the same SanDisk-branded card reader, I’m able to get the full 20MB/s read and write speed as advertised. A V30-rated card should not be 75% slower than a C10-rated card.

This review us about the 32GB, 64GB and 128GB versions sold by this particular seller.
As there are so many fake cards being sold on Amazon and just about everywhere else one needs to be very careful when buying these. Usually if it seems that the price is too good to be true, it usually is. I thought around £10 for a genuine Sandisc 32GB Micro SD card, class 10 was about right seeing as the bigger cards are the ones most required for today’s devices the smaller ones are cheaper. I had also bought one of these exact cards from this seller before and I did a test and believed it was reporting a genuine capacity. I left a five star review for that.
The last time I bought one of these 32GB cards I tested it by transferring around 32GB of various sized files from my PC to the card, it copied just under 30GB so it was successful as the rest is used by the system. I posted a screenshot of it in order to show other Amazon purchasers, but at that time I had no real idea on how the ‘fake’ cards lied to the computer (and so to the buyer).
Since then I’ve found out that although the card will show you that all the files were successfully transferred to the card, they may not have actually been copied at all!
The real test would have been accurate had I tried to transfer them from the card back onto the computer, I didn’t do that so I may have been in error, I hoped I was not when I decided to properly test the new ones I’ve bought over this last two weeks. A new 32GB card and one each of 64 and 128GB cards for dashcams, all three from this seller. In case some people had bought one based on my review. This review is to replace that one.
Since then I’ve found out that it is in fact not the actual memory chip in these cards that reports usage and space to the computer, it is the controller chip that sits between the memory/storage and your computer, and it is this chip that is reprogrammed to tell the computer how much memory/storage the fake manufacturers want you to believe is in it.
So, I downloaded a free verification programme called with H2testw. This is the one that most places and sites will tell you is the go-to software for testing for fake cards. It can take a while as it is thorough, both writing and verifying files it filles the cards with, but it is worth it as it can prove a fake which will help in the return and refund process as you can give hard data.
With H2testw, I tested all 3 of these cards with the ‘Write + Verify’ option and they check out fully, ALL are indeed genuine 32GB, 64GB ans 128GB cards and in that respect are not fakes as far as capacity is concerned.
As for the manufacturer, well the printing on the cards seems very crisp, solid colours and not grainy, and the knock-out (for hanging on display shelves) is missing which is usually a good sign. I assume they are genuine Sandisc cards and not fakes, otherwise the manufacturer would have faked the capacity too.
So here are the details after I did the capacity test with H2testw:
32GB Card Results…. Test finished without errors. You can now delete the test files *.h2w or verify them again. Writing speed: 17.4 MByte/s Reading speed: 19.2 MByte/s H2testw v1.4
Here are thecresults of the test for the 64GB card:
Test finished without errors. You can now delete the test files *.h2w or verify them again. Writing speed: 62.2 MByte/s Reading speed: 82.1 MByte/s H2testw v1.4
I forgot to copy to clipboard the data for the 128, but it passed just as the two above did. I promise.
Do not be concerned with write speeds for the 32GB card, the multi card reader I used for that test was a USB 2 so it will be slow. I used a new USB 3 reader to test the 64GB and 128GB, hence the much better speed on the 64GB.
