What is the difference exactly between the 3D-NAND (or V-NAND) architecture TLC and the regular non-planar MLC?
I really can't tell the difference exactly, because stupid Google always compares 3D-NAND TLC vs Planar NAND MLC.
The only difference I found was when I went to compare two of such SSDs on an online benchmark, and it was slightly in favor of the 3D-NAND TLC SSD.
The SSDs in question were:
Samsung 860 EVO vs Kingston HyperX Savage.
For 5 years now, I've used the HyperX Savage (250 Gebibytes, which translates to the 232 Gigabytes. It's actually 222 on my drive now, but that's a technicality), and the performance never disappointed me. The only issue I have is with the storage, which is slowly becoming more limited. Of course I'm planning to do a clone and migrate, but I just want to know what exactly is the difference between the aforementioned architectures (I mean, what EXACTLY is the difference, and how it affects their longevity).
Thank you!

3d nand and v nand are the same technology, They stack the nand flash for more effiecency, without degrading performance. different wording. Ussually 3d/v nand is always TLC.
Dont choose an ssd based on marketing terms, and even then dont choose an ssd based on weather its MLC (2bit per cell) or TLC(3 bits per cell). Yes technically the lower bits bits per cell is better but its better to look at reviews if you want the actual performance, and the quality of the nand flash can affect longevity sometimes more then the bits per cell. So look up the manufacturers claim for estimates.
Samsung 860 evo is tlc and the 860 pro is MLC, but they have nearly identical speeds in the real world performance tests, and both will last long enough for any consumers needs.
