Power Measuring Crucial BX500 240
I ordered a Crucial BX250 because it was several times recommended by german magazine c't (Heise Verlag). It was also part of a recommendation for a DYI low power system "7-Watt-Mini" in c't 24/2019.
Unfortunately I can't understand this recommendation: The SSD has low write transfer rates and has a high power consumption on write. And even its (low) power consumption on read is higher than Corsair, Kingston and Patriot have.
