The microSD drives we use are designed for Dashcam systems. These cards are rugged, built to withstand extreme heat and cold, which is perfect for being left in a car year round, and have a write speed that far surpasses the minimum Tesla requirement (4 MB/sec).
Regular USB flash drives cannot withstand the constant recording that takes place with Dashcam systems and will fail…probably when you need it the most. microSD cards, specifically those in this package, are up to the task and can handle the burden.
