Sufficiently fast MicroSDXC memory card for 4K game cameras, action cams, surveillance cameras
The K&F Concept microSDXC UHS-I memory card 64GB is delivered together with an SD card adapter in a transparent packaging and can be removed relatively easily from the same. According to the manufacturer, it is advertised as a UHS-I U3 card, so it should have a write speed of at least 30 Mbytes/s.
Like the manufacturer, I used the "H2testw" tool to test the SD card's speed. For the test, I had a 1GB file written and read via a 3.0 USB interface with a USB 3.0 card reader. H2testw achieves a write speed of 42.0 Mbyte/s (23s), the read speed is 77.7 Mbyte/s (12s).
Conclusion: The card and the adapter are well made, and the contacts also make a solid impression. This card is more than fast enough for use in a 4K trail camera, action cam, surveillance camera or dashcam!
