I'm not sure how to format it 4k, but this is how Frédéric set it to 512

Copied. Let me try to find Intel P3700 firstly.
Thanks to Lenovo, they lent me P3700 PCIe SSD for bcache testing and
debug. Now I format the card to 4K sector size and see the new 4k sector
size from fdisk output.
I start to run fio with 8 io jobs and 256 io depth, 4K random write. Let
me see what may happen. If any one has advice to reproduce the
non-aligned I/O error more easily, please hint me.
