SD card wear after 2yrs of mild use

[speedingcheetah]

{I am posting this thread in the VIOFO A119 Mini 2 section, as i that is the dash camera these SD cards have been used in. Feels more relevant here than in the forms general/Off Topic section (mods feel free to move this thread if it fits better somewhere else))

I recently have tested my SD cards that i have been using the last about 2yrs in my VIOFO A119 Mini 2 cameras.

I have noticed a decrease in performance reading/writing for copying off files to PC and wanted to see if the cards still tested as to spec.
They both still function fine in the dash camera, with no errors reported by the camera (at the time of posting)

Cards: (purchased within 1 week of each, on Sept 26, 2023)

VIOFO 256GB High Endurance (Industrial) (used in front cam)
Samsung Pro Endurance 256GB (used in rear cam)

(Purchased 9-12-25, unused)
NEW VIOFO 512GB High Endurance (Industrial)

Usage: I would consider "mild to moderate", being at the minimal, less than 40min of recording every 4 days, and at the max, 2hrs 2x a month.
Both quite hot temps, and quite cold.

Curious did you format the cards in the computer before running the test? Or just take them out of the cams and run it?

What speeds does VIOFO publish for their cards?

MicroSDXC 'Industrial' cards are generally built to withstand a broader temperature range, vibrations, dirt, etc., and not so much for speed. Though some manufacturers are claiming they make high-speed industrial MicroSDXC cards.

I've searched high and low for technical tools that can access the endurance data for various brands, but had zero success. My Micron card's brochure boasted that a tool is available, but I got no response when asking for it. It would be neat to see how much data has been written, and allow pre-emptive replacement decisions.

Made no difference. I ran the test before and after a format in the computer, preserving the cards file system ( not changing it to NTFS) Identical results.
