I was thinking that a fast sd card with a pi 4 or asus tinkerboard would really make volumio work quickly
I found an article which is not promising but then in the comments:
I found only one test where an A2 card achieved true A2 IOPS figures: techradar.com/reviews/micro … uhs-i-card
Maybe someone should check the kernel sources for the Ulefone Power 5S which they used for testing.
Is this of interest?
