Discussion

Well, I seem to be on a quest to see not only which microSD card will endure the best, but also which industrial-grade microSD card will endure the best. I wasn’t able to find any on either Amazon or AliExpress — at least, none that were within my budget (although in hindsight, I realize that I may have not looked hard enough, because there absolutely were), so this card marks the first use of a supplier other than Amazon or AliExpress for this project.

Unlike the SanDisk Industrial 8GB, this card came in retail packaging. However, this card is missing the color-shifting stripe that the other Kingston cards have. If you look at the product pictures, it looks like the 8GB model is the only one that doesn’t have this stripe — the 16GB and larger versions all seem to have it.

So far, I’m actually liking this card. All performance metrics were above average, with write speeds (both sequential and random) being more than one standard deviation above average. The lowest single sequential write score puts it in the 81st percentile, while the lowest single random write score put it in the 88th percentile. This would actually make it faster than the SanDisk Industrial 8GB — and to boot, it’s not skimpy, whereas the SanDisk Industrial 8GB was.

All three samples are currently undergoing endurance testing.

  • Sample #1 has not yet the 2,000 read/write cycle mark. It is currently expected to get there sometime in June 2024.
  • Sample #2 has survived 2,359 read/write cycles and has not yet experienced any issues.
  • Sample #3 has survived 2,365 read/write cycles and has not yet experienced any issues.
