Samsung PRO Endurance 32GB 100MB/s (U1) MicroSDXC Memory Card with Adapter (MB-MJ32GA/AM) , Black/White

I've tried a lot of different microSD cards over the years. They've ranged in capacity from 16GB to 512GB. I've tried many name brands and a few no-name brands. The most dependable cards I had used before were from San Disk and Samsung. Even those discs would eventually be corrupted by the daily power cycling of the RasPi systems. The machines were always shut down properly before being powered off, but the microSD cards would still fail after a couple of months.Then, I saw these Pro Endurance cards from Samsung. After reading about them, I realized these were made to be used the way I was using them. I basically had DSD or HiRes music playing from a partition on the microSD cards straight into DACs connected to audio amplifiers 18 hrs a day all over my home. So, I ordered a couple of them. I created my normal dual-partition combination boot drive plus data drive SD image on each of the Pro Endurance cards. Then, I replaced the cards in two of the music players with these new cards.Before trying these cards, the longest I had any microSD card last was under 2 months. I've been running those two Pro Endurance machines for well over a year, now. They still work perfectly. I am blown away by the difference in longevity. If I could always use these, I wouldn't buy any other card. Unfortunately, there is one major problem with these cards. These cards max out at a paltry 128GB. My music collection won't even fit on a 512GB SD anymore, so 128GB is just out of the question. So, in order to keep the dependability of the boot drive intact, I had to move the audio files onto their own large thumb drive.As a result, I just buy the smallest size of this microSD disc now and use it only to boot the systems and then start the media player software. All of the constant file access for playing music is hosted on the USB thumb drive, now. This two-drive approach is a very expensive solution to get reliable booting plus enough storage space for my music collection, I would entirely prefer to put a 1TB microSD into the Pi then split it into two partitions. It would eliminate the bulk and awkwardness of having a thumb drive sticking out of the Pi.Sadly, that's not possible with the largest size only being 128GB. So, I love these cards, but I hate that they are not available in the size I really need. For now, they're only useful as a reliable boot device. Still, they work so well, that my Pi builds boot every time, now. I definitely recommend these, if you can live without the larger disc sizes.-----Thanks for reading!-Bill-----* If you found any of this information helpful, please let me know by clicking "Helpful" below.-----

I didn't realize there is a difference in cards for cameras and just plain storage. After buying two cards that were useless in my dashcam. After some research I realized I was buying the wrong card, these are perfect for camera and dashcam applications. Well worth the money and an asset to have when people get stupid and you then try to lie to the law enforcement officers that show up to clean up their messes. This does not replace a card for a dash cam it is a new card for a cam that came with a 4gig card that was pretty much useless because it was too small. I can now record my entire trip to Vegas With a dashcam rolling, you have indisputable proof of what went down, put one in front and back and one on each side of the vehicle you can even get the boneheads that pull up beside you with that red ass road rage looking to take it out on some unfortunate victim because they are so brainless they have to take their frustrations out while driving. I fully endorse the use of these cards to capture the worst of humanity.

Got this strictly to use on a Roku device. Worked on model was #4662RW released on August 14, 2020. Be very careful if you've never dealt with an micro sd card before because these things are hella small.And yes I wrote "these" as in plural the image shows one is an adapter and the other is the actual micro sd card thus the "micro" wordage. This thing is smaller then a pinky nail an a grown adult.On the Roku you only need this the micro sd and not the adapter, so you can store that away. Install it with the "teeth" pointng upwards not downwards if you have a Roky device with a micro sd slot behind the device. It will load channels faster and save channels that won't fit because it ran out of file space on the Roku device itself.

Great memory card for most devices. I've had no memory issues using this device.

If you know about Raspberry Pi, then you know that SD cards often suffer from degradation and failure after being used as the storage device. I make sure only to buy trusted brands and make every effort to avoid counterfeit products, but still have had issues with SD cards failing after a year or so of use in a Pi. Even when I make sure to always do a safe shutdown and even enable read-only mode...SD cards still fail! I hope that the claims of this products better "endurance" by Samsung are true, and that for a couple bucks more this product will save me time and hassle of replacing and re-imaging SD cards.Time will tell.....

I put it into a cheap feature phone. I'm not really sure why or how I ordered such a small card, but I did. It wasn't really what I wanted, so I palmed it off on an unsuspecting young man who needed a hand-me-down cheap phone. But, the card worked flawlessly during the time I used it!

Raspberry Pi single board computers are known to chew up micro SD cards. Not only can an endurance micro SD card extend the life of the storage, but also using a distribution with log2ram (or a syslog server) can take that even further. I use the DietPi Debian based distribution (which uses log2ram by default) for my Raspberry Pi(s) which alone has extended the life of my micro SD cards... but with a recent failure I have upgraded to these endurance micro SD cards and the performance is more than adequate.

So far so good currently using on my Nextbase 622GW Dash cam.
