After a few years of post-pandemic SD card troubles, I took a gamble on this: https://www.amazon.com/gp/product/B08TJTB8XS/
Suffice to say, I’m very pleased with the performance and price on this one.
Average speed: 2978.04 kb/s, 36.37 simultaneous audio streams on a proffie v3 (SDIO Default speed).
Average speed: 1292.96 kb/s, 14.92 simultaneous audio streams on a proffie v2.2
Have to convert from exFAT to FAT32, but once that’s done, pretty damn good read/write to copy font files and no audio tics.
