So a few days ago the wife brought home a dash cam from the casino. She's on the sucker list so they lure her and her money back as much as they can. The dash cam was a super cheap one but caught my interest some. I then order a better one from Ebay that's incomplete (no wires), I used the power wire from the gifted one.
Now here's what the post is about.
I measured linear read speed of a class 4 4Gb micro SD card placed in a USB 3.0 card reader plugged into a USB 3.0 port, it was only around 12 Mb. Then I measured a 32 Gb class UHS-1 micro SD card and got above 90.
I've been using the dash cam for about 3 days now, just about done with it, works really good but........
