    • Solid endurance card — dependable for dash cams and 24/7 recording
Capacity: 256 GB
I’ve had cheaper cards fail in less than three months, but this one feels like a safer investment when the recordings actually matter. I’m using it in a dash cam, and it worked instantly without any formatting issues. Compatibility has been spot on — it also ran fine in a Wyze security camera when I tested it there. The 256GB capacity is plenty for continuous loop recording. In my setup, it gives me well over a week of 1080p video before it starts overwriting, which is more than enough. File transfers are quick with the included adapter, and the card fits securely without wobbling. Playback on my laptop has been smooth and reliable, no stuttering or corrupted files. Even in Florida heat, it hasn’t overheated or shown errors, which is something I can’t say about cheaper brands. ⭐ Verdict: Tough, reliable, and worth it if you need a card that can survive heat, constant rewriting, and heavy use. ... show more

    • The High Endurance feature means it's built to withstand continuous writing and rewriting
Capacity: 256 GB
I've always had good success with the SanDisk brand of microSDXC cards, and my recent purchase of the SanDisk 256GB High Endurance Video microSDXC Card with Adapter has exceeded my expectations. When I paired it with my new Insta360 Ace Pro action camera, the performance was nothing short of stellar. The card is designed specifically for high-demand applications like video recording, which is crucial for an action camera that captures fast-paced, high-resolution footage. With its generous 256GB capacity, I can store plenty of videos and images without worrying about running out of space during my adventures. The High Endurance feature means it's built to withstand continuous writing and rewriting, which is essential for recording long sessions without degradation in performance. What impressed me the most was how seamlessly this card integrated with my camera. From the moment I inserted it, the camera recognized the card instantly, and I was ready to start filming in no time. The write speeds are fast enough to handle the 4K video recording capabilities of the Insta360 Ace Pro, ensuring that I never miss a moment of action. Additionally, the card is competitively priced compared to similar products on the market, making it a great value for anyone looking for reliability and performance. I appreciate that SanDisk has a strong reputation for quality, and this purchase has reaffirmed my trust in their products. In summary, I can't recommend the SanDisk 256GB High Endurance Video microSDXC Card enough. It just works! ... show more

    • A great value for an awesome storage solution
Capacity: 256 GB
SanDisk High Endurance 256Gb is an excellent choice for dash cams with a price tag that does not shock the senses. I was a bit concerned because of the price that it would not hold up but it is flawless so far. It works well with my dash cam and I believe it would be compatible with many brands. In reviewing multiple images I see that the quality of these still pictures or snap shots are clear as can be. The videos are also very good with no artifacts or anomalies showing up, and the 30 and 60 frames per second are stable and completely useable. I can recommend the SanDisk HE 256GB, and if you are looking for worry free storage in many applications where quality is paramount then this is a great choice in my opinion. ... show more
