Question Is this SSD compatible ?

[wm3797]

My ASUS Z390-P motherboard has a PCIE 3.0 x4 slot. Will 250 GB WD Black SN750 SE, a PCIe 4.0 x4 ssd, still have the 3200 MB/s read speed and 1000 MB/s write speed ?

Yes.

Yes.

Do PCIE GEN 4 ssds maximize the PCIE GEN 3 slot speeds ?!

Do PCIE GEN 4 ssds maximize the PCIE GEN 3 slot speeds ?!

In theory, yes.

But wouldn't be "faster" than a good quality PCIe 3.0 x4 device.

What do you recommend for good quality PCIe 3.0 x4 device ?

Samsung 970 EVO Plus.

How much read / write speed loss would the PCIe GEN 4 ssd experience in Gen 3 slot, if compared to a Samsung 970 EVO Plus ??

It would be no faster or slower than the 970 EVO Plus.

Even if there is a difference, that would only be seen in artificial benchmarks. Not actual use.

 

[USAFRet]

And if the WD drive is rated at "3200 MB/s read speed and 1000 MB/s write speed "....a 970 EVO Plus (3,500 / 3,300) would be faster, no matter which M.2 ports were involved.
