You can use the same thumb drive, hard drive, or adapter with sd card for your music and dashcamera.
I use a high end Sandisk thumbdrive (256gb if memory serves). After 10 months I’m starting to get the “drive is too slow” error sporadically. When I buy again I’ll likey try the puretesla setup as its gotten good reviews. There are a ton of options. The dashcam rated SD cards are argued to have better life expectancy.
