Paid 90 dollars on 2x NVME m.2, 4Tb each, SSDs.
One can't be detected. (but was able to revive on a laptop, which temporarily died from there, and transferred to PC, again doesn't detect)
The other one, data transfer slows down significantly and shows "corruption" error
when downloading into it.

So tomorrow, going to investigate further on it with a software...

When things are too good to be true... It usually is.

What a waste of time and money....
