-I (capital i)? if this isn't supported, then there is no way to fix. but I remember using this test on armbian and it worked.

Yup it is. See my results below. IIRC the iozone version is relevant, way back working with Thomas Kaiser we worked out some discrepancies were version related.

All tests on my RockPro64.
My 512G Adata SX8200Pro NVMe (not as fast as my Samsung SM981 but a whole lot bigger)
Code:
$ iozone -e -I -a -s 100M -r 4k -r 16k -r 512k -r 1024 -i 0 -i 1 -i 2
Iozone: Performance Test of File I/O
       Version $Revision: 3.429 $
Compiled for 64 bit mode.

And a 32G class 10 micro SD, one of my better no-names! Yup - today (newly formatted & empty) it beat the Evo+ in 4k random writes, mainly as the Evo+ is nearly full so the test file was placed at the end of the disk. On a good day my Evo+ are closer to eMMC performance.
