The A1 is rated for 1500 read and 500 write IOPS, with a sequential transfer speed of 10MB/s. The SD Association writes:
SanDisk claims it can be used for recording video, not just storing it. But it’s not going to be fast enough for 4K data; Class 10 devices are limited to 10MB/s of sequential write performance. The 100MB/s speed is a reference to read speeds; write speeds are lower and likely closer to the 10MB/s sequential target mentioned above.
The Sandisk 400GB microSD card is available for sale on AMAZON US at USD 249.99.
