My thought too. Appreciate the authors effort; but given how tight all the numbers are along with the 5 tests, if I were the experimenter I'd feel like this was a big waste of my time and inconclusive.
No need to worry, I often feel like what I'm doing is a waste of time. I do agree with what someone else said though as I feel like whilst the sequential reads and writes on most boards are largely the same, the random reads/writes are a little more varied and this may be what people are looking for. In either case, if a £5 card performs largely the same as a £15 card, I'd say it was worth doing for the money savings. Whether that £5 card will last as long as the £15 one is a different matter but hopefully with some of the other tests I'm doing, we'll find out!
Haha I know what you mean! It was just a nitpicky thing, I found this interesting nevertheless.
Not at all IMO. Concluding that they all perform about the same is informative in and of itself.
As a reader, I found this more interesting as an IO benchmark of various SBCs. While it may not have been the first benchmark of its kind, I don't really seek out that information, so this was interesting to me at least.
