SSD with and without DRAM difference? (and one other question)

So TLC and 3D TLC has 0 practical difference for me, more as that they might survive more writes than regular TLC and are cheaper to make somehow?

AFAIK virtually all SSDs are 3D NAND now. It was a big part of what allowed SSDs to break out and become both large enough capacity and cost effective enough to compete with (and largely overtake) HDD storage.

 

It has nothing to do with TLC one way or another.

Than why does samsung has TLC in specification and adata has 3D TLC?

 

But let's not dig too deep for fairly casual implementations.

 

980 is among one of the right choices along with being fairly cheap and Adata would give me similar performance,

 

right?

It's 3D or Planar (2D) ... it has to do with how the memory cells are constructed on the silicon. Nowadays pretty much everyone makes 3D because they can put more cells on a die, so it's more profitable.

Just like they don't say Samsung 980 has a SLC cache, they just default to saying TLC because whether it's planar or 3d has very little relevance and importance to a consumer.

 

It's a detail that's not important, like you don't care if your DDR4 stick has chips that store the bits in a 8 bits x 512 M arrangement or as 16 bits x 256 M inside the chip... or you don't particularly look to determine if the stick is Single Rank or Dual Rank DDR4 - it's DDR4 and that's all you care about.

 

You're seriously overthinking this ... good for you for asking so many technical stuff, you'll learn something, I hope ... just don't stress yourself too much with these choices.

But in things like RAM it actually makes a noticable difference in the high end, right?
