That seems like good advice. I am not sure on @Knightshade's statements since I can only go off of what I read and manufacturer's recommendations. I even called Samsung and their tech support told me that they recommend SD card over their USB drives for continuous writes. Maybe as @Knightshade stated though, it's negligible for how long it will take before one fails over the other.
I expect (or hope anyway) they'd tell you (Samsung being they) to specifically buy the Endurance Pro card- since that's the one of their many SDcard lines they actually warranty for dashcam use- with them explicitly excluding warranty for such use on other lines of SDcards.
You can certainly get a USB key with similar high endurance memory though it's less common (because sdcards being physically smaller tend to be what dashcams are built to hold/use
But yeah consider the math- let's say you run the cameras 24/7/365 on a 128GB key.
Even "regular" types of flash are rated for 3000-5000 cycles typically.
That's 1,5MB/sec, which is a bit over 126GB per day. Or 1 cycle per day (slightly under).
At 3000 cycles you're good for 8.2 years.
At 5000 it's 13.69 years.
And again that's running Sentry/dashcam 24/7. If you only use it 12 hours a day that's between 16.4 and over 27 years of life.
By all means I'd expect Samsungs Endurance Pro to last longer. But who is likely to need it to?
