Unfortunately a bit too slow when writing
The scope of delivery of the 64 GB micro-SD memory card from K&F Concept also includes an SD card adapter.
For speed tests on the computer, I used a USB-A memory card adapter on a free port.
The micro-SD memory card was recognized immediately without any problems, the manufacturer had already pre-formatted it with FAT32 and a free storage space of 85.2 GB is displayed in Explorer.
Significant fluctuations in the data stream became apparent when writing a file of almost 4 GB in size. This varied between approx. 33 - 45 MB/s. When reading, on the other hand, around 89.5 MB/s were consistently achieved.
Conclusion: I think the storage capacity and the performance when reading data are good. Since the writing speed does not consistently stay above at least 40 MB/s, I cannot recommend it for recording 4k videos.
I hope this review is useful
