Just bumped into this comparison of makes/sizes of card in various cameras, and with real read/write speeds tested.

Very interesting comparison. My latest SD purchase, Integral 128GB Micro SD Card Read 180MB/s and Write 130MB/s MicroSDXC V30 U3 UHS-1 4k Video A2, was not on his list so I intend to run the same test he did later today.

I test all my cards with one tool to be consistent

He seems to be comparing speeds against price 
These cards have different ratings: v30, v60, v90 etc. yet he makes no mention of this.
Not a very technical test IMHO
Cheers
