An old thing
I found an old microSD card in a storage enclosure.
What an “Exceria” brand name! It belongs to the forgotten Toshiba.
Conclusion
As I expected, the performance of this old microSD card is not as good as that of modern UHS-I grade microSD cards. Just 10 MB/s is insufficient for today’s imaging devices.
I think TOSHIBA, a forgotten brand, was extinguished because of slow and ineffective cost reductions and because it had many more features than other products.
