Basically what you're saying is that I should not trust anybody who says newer TLC SSDs are trouble-free.
 
TLC has been around for a while and, from my personal experience with TLC drives from Samsung, Kingston, Intel, and Adata, I say TLC are trouble-free. There can be lemons from any maker and I have been fortunate so far. Also, I have been using an Intel 600p TLC drive in my early 2015 13" Air for about 1.5 years with no issues.

No one can tell you who you can and cannot trust as the final decision is yours to make.
 
So the answer is "keep buying MLC".
I have had MLC drives (OCZ Vertex, Intel) die on me or give me issues too. MLC drives are very difficult to find in a 2.5" form factor as they have not been made for the consumer market for years.

What episode did you experience? How old was the drive when the episode happened?

OCZ is and indicator that OCZ was bad, not that MLC is as trouble-prone as TLC.

You can still find 2.5" consumer SSDs up to 4TB.

The usual massive slowdown happened to my 850 EVO. It must have been about one year old.

I have had excellent experience with OCZ drives. The one defective drive I had was replaced and the replacement is still being used today.

Could you link me to a 2.5" 4 TB MLC drive? I'm curious as I have not seen MLC used in a consumer drive for many years.

How full is your Samsung 850 EVO? Which machine is it being used with?

Well, many people got burned with some OCZ drives before they were bought by Toshiba.

The 860 PRO 4TB is available.
 
I suppose it really depends on a person's specific need but I don't envision many people using a single 2.5" 4 TB SSD in a laptop or desktop. 4 TB of data is a lot to lose regardless of the memory chips used in the SSD.
I have been waiting for at least a 3TB SSHD for my laptop for years.
 
I was able to refresh the 850 EVO and later moved it to another laptop and it gave no more problems. It was stressful when the issue happened.
