Question Which is a better M.2, Lexar NM790 (2TB) or NV3 PCIe 4.0 NVMe (2TB)

You mean games do not use that type of data or for sequential read/writes?

Also you mentioned that 580 is an Old tech? could you please tell me in which way?

Sequential data....if you were a 10GB ISO file of a movie from one PCIe 4.0 drive to another PCIe 4.0 drive.
In normal, every day use (games), the files we see are much much smaller.

Running a CrystalDiskMark scan, the big number at the top is what is advertised.
But the smaller 4k numbers at the bottom are what really matter.

ex:
3 of the drives in my system.
Samsung 980 Pro, PCIe 4.0
Intel 660p, PCIe 3.0
Samsung 860 EVO, SATA III

The top line, outlined in blue, is what is advertised. "OMG! 10x FASTER!!"
The bottom line, outlined in red is where our actual daily ops happen. Incl and especially games.

Wow that is actually surprising, basically your slowest part which is the SATA would just be x2 less performant than your 980 Pro, but if someone were to view both based on read/writes they'd actually say it's around as much as x10 (which is not what would be needed for games)

So to sum up basically the Sequential data is for huge file moves? like moving 100GB of games or something, right? this is the only operation that I may find noticeable difference ?


I was viewing a channel that has reviewed the SN580 and did a benchmark comparing it to other SSDS, surprisingly, in gaming and other benchmarks, it is one of the highest scored SSDs.
Would you happen to know more about the SN580 WD? Have you seen reviews or anyone have it? is it really good and should I just go for it?

Note: I noticed that you disliked companies that change parts without notifying customers about it, While I was searching, I found Linus doing a video for the exact same thing on the SN550 WD

Exactly!

SSDs main benefit is the near zero access rate. Which holds across ALL SSD types.

Correct.

Correct.

So sorry, one last thing I forgot to ask is, does the sequential read/writes also affect things in games like shaders? (Whenever loading or compiling game shaders at the beginning)

If I get better read/writes then it would be even better for shaders or ?

A "faster" drive is rarely a bad thing, if everything else is equal. Price, warranty, etc, etc.

But it is unlikely you'd see any real user facing difference.
