The Samsung Magician is also handy since it can tell you if the drive is connected in a way that offers less bandwidth, as well as drive health and other SMART type stuff:
Here you can see at upper right this drive is connected as PCIe 2 x 2, which I didn’t realize, and would affect perf!
I don’t know if the “performance optimization” here is worth it either. But you can turn on a “full power mode” which
Full Power Mode allows the SSD to run at peak level (PS0) for nonstop consistent high performance
requires a reboot though!
