@royk ...thanks for your post:
1. Yes, I did dd write the image (used the orange pi users manual instructions to install the Armbian image)
2. Temps are at 30C-40C (have heat spreader installed)
3. No performance change after I added extraargs="pcie_aspm.policy=performance" to armbianEnv.txt (tested after reboot)
I have a 4TB drive and armbian has the Host Memory Buffer Size set at (HSIZE): 8192. The Manufacturer, Crucial sets the MS windows driver to 64MB, could this be the issue?
Thanks again for your help
