When ordering this I received a Kioxia branded produkt named Exceria.
I'm not familiar with this brand but own a Toshiba card which is also named Exceria, som maybe it's origin is the same OEM ?
The card is labeled "Read speed up to 100 MB/s", which would normally translate to 60-80 MB/s in a real application depending on actual conditions.
I tested the card with 4 different benchmark applications and never achieved more than 29 MB/s. Disappointing. However the write speed is the most interesting spec and rarely stated in card specs. This was a pleasant surprise as it generally clocked in at 17-19 MB/s which is about 50% higher than I'd expect in this price class. The card managed to sustain recording 4K-30 frames video without failure.
Even though read speed is surprisingly low, the write speed is surprisingly better than expected.
