Edit Reason: Clarified 3.80W as max
)
My current desktop has 2 NVME drives in it, both from HP.
Here is an extract from Smart which has indications of power usage;
Based on that information, I'd say the HP EX900 120GB would not be compatible with the Pinebook Pro.
However, if it were possible to limit the power state of the HP EX950 512GB to state 2 / 3.80W max, then I would feel more confident using that type of device on a Pinebook Pro.
Power states 3 & 4 for the HP EX950 512GB appear to be standby.
Just finished a web search to see if either drive had a firmware update, and it appears not. So my comment about the HP EX900 120GB not being compatible is probably accurate, (but only in my opinion).
Anyone else have NVME drives that they would care to share Smart output from?
