The SSD's in my laptop and desktop all have been working just fine. If they were different brands, I would suspect power problems. They were all WD Blue drives
That confuses me, or is unclear on what you are trying to say.
Is it that other brands in the same computer(s) are fine? If not it doesn't make a point.
FWIW it sounds like your 60hZ experiment checked the power to the computer.
What about the power to the actual drives after running through the Internal Power Supply .. how steady and correct is that?
I think that may be what the previous poster meant to question.
/many times going into the BIOS will reveal a basic test.
