Windows couldnt recognize 2 SSDs anymore, one was the project SSD and the other windows, I have tried several times to replug the cable and restart the computer. Now all is back online without any problems like health or something else. Thats strange.

I will order a new samsung ssd 850 pro. I think the lifetime of the 840 pro is over. The max writing is 75TB and its now at 140TB. Better stay on the safety side before the ssd kills itself.

Update:

As soon as the new SSD 512GB Samsung 960 Pro is available I will order this one. It has a datarate of 400TB writing instead of 150TB (can handle around 4 years runtime before the limit is reached) and its much more faster than all others for PCIe 3.0.

There are some trouble with 2 ssds again. The filesystem (1 file from the VM) was corrupt) and could be repaired. My windows OS ssd got the same issue with no loading programs anymore and dont react to anything. I will watch this out...

I have identified 2 programs causing some issues, 1 deleted one and fixed the other. The ssds are still in good health so there could be software related problems. Since a few weeks now there I observed no problems so far. Due a lack of time there is only sporadic work available but its available.

For the upcoming stress test I will prepare a lot more of work.
