Micron Launches 1.5 TB microSD Card With Five Year 24/7 Endurance Rating

This week Embedded World 2022 is taking place in Nuremberg in Germany and Micron decided to launch its new i400-series of microSD cards at the show. Normally microSD cards aren't worth a writeup, but in this case there are at least two noticeable features that makes Micron's i400-series of cards stand out. First is the fact that the i400 cards come in sizes from 64 MB to 1.5 TB, which is the largest size microSD card in the market to date.This is according to Micron, enough storage space for up to four months of continuously recorded video from a security camera, albeit at unknown resolution.

This brings us to the second noteworthy feature of the i400-series, the endurance rating. Micron claims that the cards will last five years in a 24/7 write scenario, or 2 million hours mean time to failure. The cards are also said to be optimised for sustained performance, even during concurrent 4K video streams being recorded to the cards. That said, Micron doesn't provide any actual performance numbers beyond the fact that all the cards are Class 10, U3 and A2 rated, except possibly the 64 and 128 GB models that are seemingly also U1 rated. All cards are rated to operate from minus 25 degrees to plus 85 degrees celsius. No word on pricing, as the cards aren't intended for retail customers.

And why not? I can think of many uses for such cards in the prosumer/consumer space. Come on Micron, do better.

I wonder how much more expensive i400 series will be vs WD Purple SC QD101 Ultra Endurance microSDXC series (1TB for example starting at 200-220€) due to 5 years warranty with 24/7 usage vs 3 years warranty with 24/7 usage.

This isn't the 2 terabytes that I was waiting for, but this is still "progress", and the most that I have seen in a long time, in this area. Now I'm wondering how many months or years it may take to reach the 2 terabyte capacity, if it was this much of a struggle to get to 1.5 terabytes.

Probably yields are low so high margin market segments take priority.

How time flies. I remember when I bought my first USB flash memory. It was a massive 16MB drive on the impressively fast USB 1.1 bus. I treated it like a gemstone and people asked me to just show it to them so they could admire this technological marvel. Twenty years later I got a fast 256GB drive as a gratis to another one which I picked by the cash register when I bought a new microwave oven and people demand 2TB memory the size of my thumbnail. The technological progress is nothing short of astonishing.

The warranty off SD cards in mobile phones, more likely not longer than one year or less.
