TCELL Gaming 256GB Micro SD Card, Nintendo Switch Compatible, microSDXC A2 USH-I U3 V30 Read 100MB/s Write 80MB/s with Adapter, Designed for Gaming Console

This came packaged in standard retail packaging and included SD card adapter, but I did not use the adapter so I cant speak to how it works. I used the card in my dashcam and it works as expected. When I inserted the card, my dashcam immediately recognized it and prompted me to format (which it did successfully). It records and plays back video without issue and works exactly as one would expect it to.

This 128GB micro SD card works very well in my dash cam. I tested this with H2testw and it comes up as accurate capacity. The speeds are right on with description and time will tell how long it will last in my dash cam because thats a rough use but I have high hopes!

I inserted this into my Windows 10 Mini PC and it was instantly recognized as an SD drive - no problem - plug and play. The 128 GB capacity is correct and I tested the card for speed by copying files and its really fast. The price of SD cards fluctuate quite a lot - this one is less than 25 bucks - very reasonable. HIGHLY RECOMMENDED! AAA+++

This is one of the faster cards I have tested. There are few others that may be faster, but anything faster for an external memory stick will be using something like M.2, which is an order of magnitude faster, but so is the price.
