This Kosher?!

An old PNY SSD died on me this week which caused me to replace it.

 

Decided to go with WD Black nvme 256 ssd. Rated read speeds were 2000+ Mbs and write speeds were 700+ Mbs.

 

Motherboard is a MSI Z97S with an i7 4790k.

 

Here are my results from Crystal Disk Mark.

 

Could the slow speeds come from an older bios running that might not support the full speeds?

 

WD Black nvme SSD 256GB

 

 

just for funsies here are my two WD 2TB drives first is a Black second is a Green.

Did you install the driver from WD's website?  Enable trim?

I have the WD SSD Dashboard installed which says everything is update and running correctly.

Not 100% sure about this, but I think your mobo only supports PCIe Gen 2 2gb/s instead of the full speed achievable in PCIe Gen 3 4gb/s

Hmm you may be right, quick look at the https://www.msi.com/Motherboard/Z97S-SLI-Krait-Edition/Specification

shows Gen2 but the overview claims other wise?

Welp. Not enough research and I screwed my self.

 

At least I got it at a huge discount on Amazon.

 

Z97 chipset does not support the full speed of that drive.

 

So effectively I have regular SSD plugged into a m.2 slot.

Because the overview is referring to CPU lanes. Not lanes from the chipset which is under the M.2 bit.

Definitely only  x2 on m.2.. I have a similar/same board from msi, I researched this thoroughly when looking at m.2 drives a few years back.
