have horrible random/sequetial speeds - Samsun 850 PROs are 3 times at
least faster on sequential, and more than 3 times faser on random/IOPS
measures.

Yes, it sure is - my experience with 'consumer' SSD is that they die
with obscure firmware bugs (wrong capacity, zero capacity, not detected
in bios anymore) rather than flash wearout. It seems that the
'enterprise' tagged drives are less inclined to suffer this fate.

Damn… but maybe your surname says it all - Don’t Panic :) But
If the same chassi/chip/backplane is behind both drives and maybe other
drives in the chassi have troubles,it may be a defect there as well.

these 2 drives, are on the regular SATA (on board)controler, and beside
this, there is 12 x 4TB on the fron of the servers - normal backplane on
the front.

Checked the SMART status. All of the Samsungs have Wear Leveling Count
equal to 99 (raw values 29, 36 and 15). I'm going to have to monitor them -
I could afford loosing one of them, but loosing two would mean loss of data.
