I have been using your cards and competitor's cards in the past, I never had the need to sanitize a card. Why do I need to sanitize cards now?Updated 9 months ago

Flash memory gets dirty as it gets used regardless of what brand it is. Every flash controller manages that flash to clean up flash when it must. But this house cleaning process that is called Garbage Collection (GC) could be triggered during your recording forcing your card to run slower as it is running in parallel and leveraging CPU resources inside the flash controller. This could cause recording to stop. In addition, with faster write speed requirements from the new cameras compared to some of the older cameras, the card dirtiness issue is exasperated that may not have been an issue on those older generation cameras. For example, an SD V60 card guarantees 60MB/s sustained write. If you had a camera that required 20MB/s, a dirty card may not trigger stoppage of video capture. But a new camera that may need close to 60MB/s requires that flash to be clean in order not to trigger the GC process while you are recording.
