    Samsung Pro Endurance 256gb Micro Sd Card w/Adapte

    I purchased the 256gb Samsung Pro Endurance Micro SD Card with Adapter. It is a great Storage Solution for Pictures and Videos and offers a significant amount of space for the Value. I got it for my 4k dashcam and it worked well for 4k recording in motion detection, but it doesn't hold up to 4k loop recording.. but it holds up with 1080p loop recording. It works well if you arent continuously recording in 4k. It does work well in motion detection 4k recording and can hold a lot of photos just fine. So Unless you plan to Loop Record in 4k then this SD card option is a great option and regardless it is still a great option and value for the money. I would highly recommend for eceryday use and fast data transfer speeds.

    Best Quality for the price

    These are easily the best available for the price. I use them in my drone, security cameras and car camera. Been using them for about 4 years and never had a failed card which includes about a dozen of them. Right capacity so that I get about two weeks before the security cams overwrite.

    Perfect performance for the price

    Solid product, what more can be said? I got an endurance card for my Go Pro since it can record in up to 8K and that just chews through space like nothing. Even with a 256 GB card slapped in there, I think I'll just put it backdown to 1080p or 4k. These videos take so long to edit. You want a legit card so get it from a brick and mortar store. I will say that I waited over a month for it to be delivered as I ordered it over the holidays. Fedex lost it, I reached out to BestBuy customer support and they re-shipped it to my house in about three days. I trust Samsung cards over others. This card is great for dash cameras, Go Pros, or other devices that write a lot of data continuously.

    Random corrupted files on my 4k dashcam.

    Samsung 256GB Pro Endurance This micro sd card comes with a SD card adapter, and I purchased this for a 4K dashcam for the extreme temperature tolerance and read/write endurance of the card. I have two of these cards, and I’m getting random corrupted files on both cards, my tested speed benchmarks in a 10Gbps hub are 28.5MB/s Write and 94.1MB/s Read. I think the high temperatures this year proved too much for card, or it could just be two random bad cards. I format the cards in the dashcam often which didn’t make a difference in corrupted files ratio.
