    • 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

    • Excellent microSD card for Tesla Model S – reliable and perfect for Dashcam/Sentry Mode.
Capacity: 256 GB
I've been using the SanDisk 256GB High Endurance Video microSDXC Card in my Tesla Model S for a while and it's been absolutely flawless. I formatted it using exFAT, inserted it into a USB adapter, and plugged it into one of the front USB ports — the car recognized it instantly. It records both Dashcam and Sentry Mode footage without any hiccups. The video files are stable, and I haven’t had any corruption or lost footage, even after long drives or extended parked sessions. The card is built for high-endurance applications, which is exactly what you need when recording 24/7 in a vehicle like this. Living in an area with both hot summers and freezing winters, I also appreciate that the card handles extreme temperatures without any problems. No performance drops, no reformatting required, and no errors from the car. If you own a Tesla and are looking for a reliable, plug-and-forget storage solution, I highly recommend this SanDisk High Endurance card. 256GB is plenty for keeping several days’ worth of recordings before overwriting starts. Highly reccomended. ... 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
