Today TDK Corporation (President: Shigenao Ishiguro) announced the gradual launch of SD Memory cards (MMRD4 series) and microSD Memory cards (MURD4 series) from January 2018. Both series support UHS-I for industrial application. The rapid progression of IoT has increased demand for smaller SD/microSD Memory cards with low power consumption for the storage of sensor information. However, as SD/microSD Memory cards for general use adopt TLC and MLC type flash memory to reduce costs, they are largely unsuitable for industrial application in terms of durability and reliability.

These would be good for those raspberry pi devices.

No application performance class logo, no interest from me, even if I found them selling at super low prices. I would hate to suffer another "Kingston SD" example in my face, where the SD card offers high sequencial speeds and then at 4K it writes with the speed of a 25 years old 1.44MB floppy drive(0.03MB/sec).
