The above is for the nvme interface and should be noted that it is x1. That means I'll never get the extra performance that these disks have to offer. However not is all lost as it makes an excellent boot device at sata speeds with the extra enhanced uefi bootablility of nvme (ie partuuid instead of hdx limitations).

Bottomline is don't bother investing in a high performace nvme disk when it will never attain that level of performance.

Life is good,

It is the same situation on the x86_64-znver1-linux-gnu host. Different chipsets but the result is the same.

Life is good,
