I have noticed that my onboard NVMEs perform close to twice as well than my NVMEs attached to a PCIE nvme adapter.
I have been using a combination of these three adapters.
when i do a benchmark on my drives they all show to have the same write rate 1.9GBPS
But when it comes to actually plotting i notice my onboard NVMEs out perform the once attached to the adapter significantly.
anyone else experiencing the same thing?
I am using a ryzen 5900 with 256GB of ram and a Gigabyte Aorus x570 motherboard (PCIE4) on Ubuntu 20
Here are a few of the PCIE adapters i have been using as well
