Good info, Mike! However!
The test that I did on the 2 sd cards I had, was just a "basic" examination of the speed comparison between the cards. One card being a name brand and the other being a Generic (I did note in my previous post that the Generic appears to be a Gigastone/Dane brand, which are somewhat Brand name manufacturers)
I think the test gives an "indication" that the 2 cards are "likely" similar in speeds for other forms of tests, such a sequential read writes, etc.
And yes, during my download speed tests, Mint 18 was showing MB/s speeds and not Mb/s.
Note also that my original post is just about the speed comparison of 2 sd cards and not about their speed, when used on a Raspberry Pi.
For use as a Class 10 memory device in a notebook computer or other device, it looks to me that the Staples Generic sd card compares favourably in speed, to a name brand sd card.
