What is the difference between MLC V-Nand and TLC NAND?

[iseeu1001]

I know I can probably google this but I am to lazy to but what should I choose as far as a 1tb ssd? I have used both samsung ssd and crucial ssd and can't really tell a difference as I am not to technical as far as what they do differently. Here is the links for the 2 ssd I am looking at so please tell me which one is better and why. I don't care about price difference at all.

Crucial MX500
Samsung 860 Evo

Samsung only because it has a larger TBW (TerraBytes Written) so that it can write more before its start to fail.

But what is the difference between MLC and TLC? The samsung is better because I can write atleast 600 tb before it starts to fail?

MLC is warrantied for longer write endurance, but, even the TLC samples are far more likely to run out of years before TBW values are challenged for 99% of most users.... (my 960 EVO is a year old, with only 9 TBW in that time, with most of that installs and Windows updates....)

If planning a life of heavy video editing, go with MLC.(850 Pro, 960 Pro/970 Pro)

Ok, the main difference here is that the Crucial disk uses TLC NAND. This uses old-style "floating gate" transistors which have been around since the 1970s.

However, the Samsung uses "charge-trap" transistors. This is the next generation type of transistor.

Which is better? Well, floating gate transistors by their very nature are prone to electron leakage. Over time, this can result in data loss. Charge-trap transistors are much less prone to this problem - as the electrons "get stuck" much better. Think of "floating gate" transistors acting like water whereas charge-trapping transistors act more like a block of cheese. You can find out more here:

My advice: just go with the Samsung V-NAND.
