NVMe VS. SATA M.2 Power Consumption

[kevinshroff]

Do we still need to swap out our NVMe drives with SATA M.2 to improve power consumption or is that no longer an issue?

I want to know that also.
I've read that MacOs doesn't have proper energy management with thirdparty NVME's.

Since macOS 10.14.6, a 3rd party NVMe SSD controller is now identified as a "Generic SSD Controller", but is unknown if this helps NVMe power management in any way. Someone would need to measure and confirm.

I've updated to 10.15.1 and still have terrible battery drain with stock Toshiba 512gb NVMe drive (BIOS says battery in excellent state)

NVMeFix.kext was added to repo recently
Had anyone tried it with stock Toshiba ssd already?

[rostopira]

Okay, I've finally tried it myself, result = kernel panic

@rostopira,

NVMeFixup.kext was just updated hopefully fixing some kernel panic issues.
