Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
This is a first I have never been able to measure the rated write speed for a SD or micro SD card I have gotten close within 4% but in this case better than rated speed I measured 51.3 MB/sec it is rated at 35 MB/sec. For the read speed I measured 95 MB/sec right at rated speed.
