Drudging up my old thread here.
Found some interesting features in smartmontools for a new Intel AIC NVMe drive I recently purchased.
In particular the sectors section.
In addition to 512/4096 we have a 'metadt' column that other drives don't have.
So extra sectors for metadata?
I would also call your attention to the Intel 670p PCIe settings. Support for SR-IOV in a consumer M.2 drive??

How bizzare the Data Center AIC doesn't have any SR-IOV support.

Running FreeBSD on Radxa Rock 3C RK3566 board
I see that RK3566 and RK3568 have different bus schemes. RK3568 adds PCIe3.0 bus. https://www.cnx-software.com/2020/12/16/rockchip-rk3566-and-rk3568-datasheets-and-features-comparison/
