Samsung's NAND is some of the best. Not sure where you get the idea it's cheap. This also 10 nm, not 19 nm.
They've performed longevity tests on modern cell performance and it's now far and away beyond what original longevity tests showed back when flash was first coming to market. The early SSD tests were not much better and in both, RAM was never taken in as a factor which actually plays a huge role in the longevity of your SSD.
Most longevity tests are actually still based on the old Compact Flash drives. Those being much smaller in capacity and of older technology did indeed have issues with short cell lifespans but that's really no longer an issue. Especially with larger drives (meaning fewer write cycles per cell over time), better wear leveling software, great over provissioning software and finally...computers with more RAM which leads to far less paging on the SDD.

It's "10nm class" but actually 19nm.

Samsung did the same thing by stating 28, 22 and 21nm as 20nm aka. "20nm class". - Advertising at it's finest, sorry you fell for it.
In regards to longevity, you're right RAM, SSD controller and other factors play a massive role, but you still have Physics come into play which simply, you cannot get around. (Simply, MLC and SLC will generally have far higher endurance than TLC at the same node.)
Because I'm feeling lazy and don't feel like repeating/rewriting what Anandtech has stated... Sink your teeth on this: http://www.anandtech.com/show/5067/understanding-tlc-nand/2

I didn't see the "class" part but based on some research, it's most likely going to be 16 or 14 nm, not 19. Samsung has been working on both 14 and 16 for a while now but nothing about 19 nm. Only Toshiba is working with 19 nm right now.
Of course SLC and MLC have a highe rendurance than TLC. I never said otherwise. In fact, I was speaking about SSD's in general with regards to their mechanical counterparts. I wasn't comparing the different cell technologies.
I did, however, get the price correct. The 1 TB model is $650.
