It elaborates on the differences in structure, capacity, power consumption, performance, and cost.

It is ideal for storing mass data as required of anSSD(Solid State Drive) orUSB flash drive.
Each cell comprises floating gate transistors that trap an electrical charge (indicating the 0 or 1).
Those 2 types refer to the logic gates used in the memory cells.
Flash Memory in SSDs
In SSDs, data is stored in cells.
Extremely small cells suffer from cell-to-cell interference leading to increased instances of errors and power use.
Thus, at a certain point, it is not feasible to make the cells any smaller.
Yet, users all want faster SSDs with more capacity for less money.
So, to continue producing more advanced SSDs, something needs to be changed.
Therefore, there comes into being the 3D V-NAND technology and its applied SSDs.
The first 3D V-NAND SSD is the Samsung 850 Pro, which is a 2TB SSD ofSATA-based.
2D NAND vs 3D NAND
What are the Differences Between 2D NAND and 3D NAND?
First of all, lets see a general introduction to 2D NAND and 3D NAND.
The industry is currently facing a very large surplus of NAND flash memory.
Significant price drops in SSD could be seen in 2019 according to some analysts.
3D NAND, also called 3D V-NAND or vertical NAND, is the newest technology adopted in flash memory.
It is just the planar NAND (single planes of NAND cells) are stacked vertically.
Yes, it is capacity!
It is tested that V NAND is about twice the speed of 2D NAND.
In this perspective, V-NAND means higher manufacturing costs yet retail price per GB.
Yet, 3D NAND still has some disadvantages as below:
What is the 3D NAND?
Why should you choose it?
This post shows you some detailed information.
Below introduces some common 3D NAND SSD manufacturers to you.
The above table only lists some important information about each V-NAND SSDs.
it’s possible for you to choose one 3D NAND SSD that suits you.
SK Hynix begins sampling its 4D NAND flash to clients.

How to Switch to 3D or 2D NAND SSD?
After picking up the desired V-NAND SSD, you’re free to put it into usage.
Yes, you have tomove your system, programs, files/folders, etc.
to the new disk before throwing the old stuff away.
After many years of usage, there must be a lot of staff on your current hard drive.
To move or copy them to the new SSD, your need some time.
And, the most important thing is to ensure the system is bootable when migrated to the new destination.
Thus, is there is a way to achieve that?

Step 1.
Download, install, and launch MiniTool ShadowMaker on your old disk.
Connect your new 3D NAND SSD to your box.
ClickKeep Trialon the top right of the screen if it asks you to buy.
On its main screen, clickToolson the top menu.
In the Tools tab, click theClone Diskoption.
Finally, clickOKandYesto carry out the migration.
Wait until the process finishes.
Finally, it’s possible for you to boot from your new disk.
Yet, it is more complicated to manufacture 3D V-NAND than 2D planar NAND SSD but worth it.
