With 80MB/s seq write speed, Kingston 90R/80W card performs flawlessly on BlackVue DR650GW-2CH dash cam that needs to record both Full HD and HD videos simultaneously while still able to provide wireless access to read the content on SD card. BlackVue DR650GW-2CH is very picky on micro SD card and won’t work on slow cards. And should work on the upcoming YI 4K+ Action Camera with 4K/60fps at highest bitrate 135Mbps too. Can it be used as part of internal storage of Android Adoptable Storage? Yes, it is working properly on my Android TV boxes. No possibly degraded experience warning here.

Advantages

  • Excellent transfer rate on both read and write
  • UHS-I Class U3 support
  • Lifetime warranty
  • Come with SD adapter
  • Decent build quality

Limitations

  • None from me

Conclusion
With price around US$35, 64GB Kingston micro SD UHS-I U3 90R/80W is the card that you don’t want to miss out. Enjoy fast read and write transfer rate speed up to 96MB/s. And supported by Kingston lifetime warranty too. More information can be found at Kingston Website. And get yours at Amazon.
