To everyone discussing here whether the title says MLC or whether the reviews says TLC, here is what I have to say about it:
Samsung just pulled a Samsung for the spec sheet of their drives.
In other words, they made a misleading marketing terminology to make their EVO line look better on the title, and completely ignored and disregarded the terminology that everyone else is using.
Here is what they did for example:
- The 860 PRO Data Sheet says the drive uses a 2-bit MLC.
- The 860 EVO Data Sheet says the drive uses a 3-bit MLC.
See what happened there? They are rebranding the TLC terminology (or triple level cell) as 3-bit MLC (a.k.a. triple level cell, too).
You can totally tell that their "3-bit MLC" has only 50% the endurance of their "2-bit MLC", the data sheets indicate that the 3-bit cells can only be written 600 times, but the 2-bit cells can be written 1200 times! (compare 600TBW vs 1200TBW @ 1TB on the 860 line).
They just pulled this one out their a** to mislead the market and profit, the correct way of calling a 3-bit cell is TLC , and a 2-bit cell is MLC.
On paper, the 860 EVO has 200% minimum the endurance of the 850 EVO, is that really so? Or is it that they are learning from statistics that they underestimated the initial endurance calculation and that their TLC holds longer than expected?
To me, this is all marketing BS and you should read the data sheet if you want to make sure you find what you are looking for.
