NVMe power issue?

[belfastraven]

It looks to me like there are problems with NVMe disks that are heavily cached with DRAM memory which uses a lot of power.
MyDigitalSSD SBXe doesn't have any form of DRAM cache onboard. Maybe this is the cause that it just works ?
There are also reports that such disks albeit slower are running much cooler.

Yes, and the new SBX eco's are supposed to improve on power consumtion over the earlier disks , I believe.  I have run iozone tests and not seen temps over 37 degrees C.   The warmest I have seen the disk as measured by smartctl -a  is 40 deg.   at the end of a kernel compilation with -j6 and all cores maxed out.   

I had been looking for relatively inexpensive storage that would iit  inside the machine and allow for decent battery life.    So far this is working.
