I just updated to 2019.24.4 and noticed that the dash cam was not working. The error message stated that the usb drive was too slow. I have been using the same usb drive for 3 months without any issues. SanDisk Extreme GO USB 3.1, 128gb. Any ideas??

I have to assume they are preparing to turn on more cameras.
The slowest USB keys in the world would still be several times faster than needed with all 8 cameras running (and it seems unlikely they'll run more than 4 but I suppose they could)
While I assume you are being hyperbolic it's not uncommon for cheaper flash drives to only write at 10-15MB/second sequentially so it's not out of the real for them to be fairly overwhelmed by multiple video feeds. .
About 30 MB/minute/camera according to my file sizes. 90 MB/minute for three cameras.
Also, they need to continue recording real-time to the Recent folder while saving files to the Saved folder.
The SanDisk Extreme GO USB 3.1, 128gb does random 4k writes at 12.2 MB/sec. It will do sequential writes much faster, but does what Tesla is doing match the sequential use case? Or maybe a new Tesla use case that is different than what they were doing?
This is true, but it may still be a good idea to buy a USB 3 drive because they generally have faster controllers and flash memory. I have seen cheap USB 2 drives with less than 5MB/s write speed.I guess I could buy a USB 3.0 stick but I’ve seen posts that say that the USB’s in the car are only 2.0 versions.
