Difference of industrial grade microSD card between ATP and Kingston

Dear Experts - I am facing an 8GB industrial grade microSD card issue when I use it with a machine as a memory part containing OS (Windows), image files, and settings. After comparing a price of each, there is the difference so much. Could you please help advise me which is a better 8GB industrial grade microSD card if comparing between ATP brand and Kingston brand? Also, why is the price of each different so much? Thanks in advance. - RR1

There is really no definitive standard for identifying a memory card as "industrial grade". Typically, manufacturers will tout their products as industrial grade if they can withstand wide operating temperature ranges of -40°C to 85°C, or if they employ single-level cell (SLC) NAND flash.

ATP recognizes that with the wide array of industrial usage applications, the "industrial" label should go beyond product specifications or capabilities. They specialize in mission-critical as well as safety (and life-critical) applications in a wide spectrum of usages. Whether they are for connected vehicles, smart factories, intelligent homes or buildings, or rugged environments and terrains. This is why they're more expensive.

That having been said, the Kingston products still meet the temperature
rating of -40°C to 85°C making them perfect for harsh environments and are durable with a rating for a minimum of 10,000 insertions. It's also IEC/EN 60529 IPX7 certified for protection against continuous water submersion for up to 30 mins at a depth of up to 1m.

So it's still a very good and durable industrial product and I would go for the cheaper option as long as you aren't putting it into the sort of extremely critical applications as listed above.
