Initial USB Drive for Sentry and Dashcam

Should be good. I did mine for the first time today, using the steps you're describing. Worked as expected.

 

Both will work- but 32GB is too small for any long term use... the dashcam system writes 7.2GB an hour- meaning it'll eat through a full write cycle on a 32GB drive in less than 4.5 hours... so you're eating 2 cycles per day even if you only are using it for say an hour of driving and 8 hours parked at work.

That's gonna kill a cheap no-name drive in not much more than a year.

More like 6 months if you run it 24/7.

(and less if you save any significant amount of video for long)

The 256GB drive on the other hand, even if it was cheap quality stuff, would be good roughly 8 times longer
