WDS120G2G0B and WDS120G1G0B difference

Hello. There are two WD Green 120G SSD M.2 drive models on the market, WDS120G2G0B and WDS120G1G0B. What is the difference?

Looks like one (WDS120G2G0B) has 3d NAND.

Hi Martin5,

So, this difference is able to define if my laptop is compatible just with one or both?

I want to know wich one i have to choose to install it into a HP 14-bp005la laptop?

Thanks in Advance,

WDS120G1G0B much better but hard to find, look for the Kingston A400

the tests show the opposite
