So my question is i have gen 3(PCI-Express 3.0) motherboard (B365 M AORUS ELITE) and want to install gen 4 Nvme m.2 ssd but will the gen 4 ssd be able to use its full speed in gen 3 mobo or i am wasting money?
Thank you in advance
 
The bandwith of PCIe3.0 is the max you can get so about 3500MB/s where PCIe4.0 can push it to 7500MB/s.
So you wanna say that i should buy gen 3 ssd because gen 4 ssd wont be able to push beyond 3500 read write speeds on gen 3 mobo is that it?Or maybe i should buy gen4 because that will push the write read speeds of that gen 3 slot to the max

In the end even if your pc has a gen 4 ssd you likely will not see much difference. The speed of SSD is so fast that unless you are running very special apps or obsess over benchmark numbers you will not be able to tell.

I guess it depends on how likely it is that you would use the gen 4 SSD in a different machine in the future that could use the full potential. It also depends on how much cost difference there is. If you were asking about PCIE 5 devices that would be harder question because they are very expensive for something you can't really use today.

Ok so im gonna put two different ssds and you should tell me which one should i choose the difference in price is like 10 $
1.https://www.kingston.com/en/ssd/nv2-nvme-pcie-ssd -65$
2.https://www.samsung.com/sg/memory-storage/nvme-ssd/980-500gb-nvme-pcie-gen-3-mz-v8v500bw/ -$75.00
 
Assuming they are both 500gb.

This is a much more complex question and shows why the PCIE type is not the critical question many times. In this case both devices will not be limited in any way by the pcie 3.

The pcie3 device you are looking at appears to have a better write time. This is all related to things like how much dram cache there is. That also likely is what partially makes it more expensive....then again it could be just because it has the name samsung on it.

This quickly leads to the next question of how long does it actually write at the higher speed. At some point it will exceed the cache and the underlining memory speed will dictate the write speed.

You would have to find the benchmarks that show what the write speed is on these devices when the cache is exhausted.

When you start to really dig into all the specs you quickly find out there are not simple answers because there is always a trade off. Overall I think you will be happy with either drive.

Maybe check for reviews to be sure the certain models do not have issue. Samsung got big egg on its face when it released a bunch of drives with bad firmware that I forget the exact details on. It is not the older ones you are looking at but I would check both to just be sure.
