The “Up To” speed of 150MB/s are not specified to be Read or Write, refer to images
As the packaging states “Transfer a full-length movie in less than Blah blah Blah seconds”, calculations may be assummed the specified speed is for both Read and Write ?
This may be construed to be misleading product information.
In the Far East where people are a sticker for details and nothing but exactness is acceptable or they’ll complain complain and complain some more, the Sandisk packaging DOES state both Read and Write information !
So the question to be asked with regard to Western packaging is “Why” ?
