> It's possible to configure NVMe devices with power caps, but the 970 Evo in the article loses 95% of its performance if you cap it to 3.6W, which is its lowest operational power state.
Heh, yeah I saw about 4 MiB/s max read speed with similar enclosure plugged into USB 3.0 port (I guess it self limited for a while). Meanwhile much less power hungry SATA SSD + USB-SATA bridge worked at 400 MiB/s there.
I don't know why the Samsung is so bad at low power. A WD SN850X in the same machine has no noticeable change in random read performance with a low power state configured. It's half the speed of the Samsung at full power, but 10x as fast at low power.
