No need for the condescension really.
Everything you posted explains that as a NAND cell reaches the end of its life if is more susceptible to errors. This will happen with any NAND type, MLC or TLC. So back to my original point, if you want to spend more money on a MLC NAND SSD so this does not begin to happen for 70 years instead of 23, go for it.
Post up any data you have on people losing data due to TLC NAND.
I believe the OP has the information needed to make an informed decision either way.
I didn't mean to be condescending. Honestly. In the circles I normally discuss this in, this information is considered obvious.
But with regards to attitude on a forum post, as childish as it sounds, I feel you started it. I had written up a larger post which points out why I thought so, but I erased it because it's simply not worth spending time discussing our misunderstandings in the public. Sorry.
To answer your query: "Post up any data you have on people losing data due to TLC NAND."
I don't have any direct data that I can provide you on rates of user data loss from TLC. There's simply not enough consumers out there with TLC to get you a good sampling of long term real-world TLC SSD usage and failure rates. Any information I've seen regarding test data was confidential to the sources I discussed it with.
The most I can do with public information at the moment is provide you with the physics and operation of NAND, the differences between MLC and TLC, and show you how some of the differences makes it harder to reliably write/read data to a cell, and then how each of these differences compound with each other to approximate an exponentially worse uncorrectable bit error rate. Much of this has actually been summarized on Anandtech's SSD articles in the past, but those three links I posted have almost all of it with just a little more depth.
