Performance of Samsung SSD 970 EVO 1TB on NUC5i7RYB

I have just installed a brand new Samsung SSD 970 EVO 1TB consumer drive into my 2½ year old Intel NUC5i7RYB.

When I read the https://s3.ap-northeast-2.amazonaws.com/global.semi.static/Samsung_NVMe_SSD_970_EVO_Data_Sheet_Rev.1... SSD data sheet I get to expect sequential read performance about 3400 MB/s and sequential writes about 2500 MB/s. However, the actual performances scores I read out from Samsung Magician are only about half (1525 MB/s and 1507 MB/s):

I am using the default Windows 10 NVMe driver; BIOS version etc. are relatively recent (v369). This is my system summary:

I am aware of other threads in this forum with similar questions (such as this one: ) - but none with the exact same combination of NUC, O/S and SSD.

What can I do reach the advertised performance of my new Samsung SSD ?

Thanks,

/Thomas.

Have you tried installing the Samsung NVMe SSD driver?

I suggest that you try it. You can always remove it if it has any side-effects or doesn't help.

OK, now I tried it (and validated through device manager, that the Samsung driver was properly installed).

These are the performance results before installation - i.e. with the Microsoft NVMe-driver:

And these are the performance results after installation - i.e. with the Samsung NVMe-driver:

So my conclusion here is, that the Microsoft driver performs better than the Samsung driver; but still it underperforms with a factor 2 compared to my expectation of the system's performance.

Hello tbsalling,

 

 

I am following up with your case and see that we have not heard back from you.

 

 

Are you still experiencing the performance issue with the NVMe drive?

 

 

If you need more assistance do not hesitate to reply.

Hi David,

Thank you for following up.

Unfortunately, I have not found a way to solve this issue.

The Samsung EVO 970 SSD as such works fine in my NUC - but the performance numbers are still lacking similar to what is shown above.

Any input on how to improve these numbers to look like the advertised specs is greatly appreciated.

Thanks,

/Thomas.

Hi David,

Thank you for your help.

I attach a fresh performance measure from Samsung Magician, the full output of SSU, and the full output of dxdiag.

Best regards,

/Thomas.

Hello tbsalling,

 

 

Thank you for your response.

 

 

Upon review of the information and the reports I was able to determine that the BIOS version of your unit is not the latest. Please go ahead and follow the steps in the link below in order to update the BIOS:

 

 

https://www.intel.com/content/www/us/en/support/articles/000005850/mini-pcs.html https://www.intel.com/content/www/us/en/support/articles/000005850/mini-pcs.html

 

 

You can get the latest BIOS version for your device in the link below:

 

 

https://downloadcenter.intel.com/download/28026/BIOS-Update-RYBDWi35-86A-?product=87570 https://downloadcenter.intel.com/download/28026/BIOS-Update-RYBDWi35-86A-?product=87570

 

 

After you are done, please boot the system and run the utility again to see if the speed is still not the expected one.

 

 

I hope this helps.

Hi David,

Well spotted. As you can see from the attached SSUreport1.txt I have now upgraded the BIOS to the most recent version.

Unfortunately, it did not have any affect on the performance of the SSD:

Best regards,

Hello tbsalling,

 

 

Thank you for your response.

 

 

I am currently reviewing the information to see if we can address the problem in the best way, please allow me some time and I will be getting back to you as soon as possible.

Hello tbsalling,

 

 

Thank you for patiently waiting.

After doing some research, I found that the Intel® NUC Kit NUC5i7RYH does not support M.2 NVMe; it supports the following SSD drives and bandwidths:

With this in mind, the Samsung* SSD 970 EVO NVMe M.2 1TB is running within specs on this system.

Oh. So I need a quicker NUC to keep up with the new SSD. Thanks for clearing this up.

Hello tbsalling,

 

 

Thank you for your response.

 

 

In this case, I can recommend you to either work with the system the way it is, since it is working within specifications. However, if you are looking to upgrade, I can only recommend you to make sure that the unit supports NVMe drives. This way it should run at the advertised speed of the drive.

 

 

Here is a list of the NUCs and the technical specifications of each of them:

 

 

https://www.intel.com/content/www/us/en/support/articles/000005545/mini-pcs.html https://www.intel.com/content/www/us/en/support/articles/000005545/mini-pcs.html

 

 

By searching for "NVM" you should be able to find if the NUC supports the NVMe drives.

 

 

I hope this helps.

The NUC5ixRY (Broadwell) series does have NVMe support, at least with latest BIOS 0373. I have successfully installed Windows 10 (and Windows Server 2016) into a Samsung SM961 PCIe NVMe 512GB M.2 SSD with my NUC5i3RYK. Windows Device Manager clearly shows a "Standard NVM Express Controller" supporting the Samsung NVMe SSD.

The M.2 2280 SSD slot in this NUC series supports PCIe x4 Gen 2 (not Gen 3), so the theoretical bandwidth is 20Gbps, not 32Gbps, My SM961 delivers a sequential read speed of about 1600MB/s. When installed into a Skylake-based NUC such as NUC6i5SYH, the read speed of this SSD is closer to 3000MB/s. The Broadwell series NUCs talking PCIe x4 Gen 2 cannot take advantage of modern NVMe M.2 SSDs supporting PCIe x4 Gen 3 speed.

The only issue I have pairing an NVMe SSD with NUC5i3RYK is system occasionally failing to recognize the SSD at bootup, and Windows throws a winload.efi failure screen. Warm booting (Ctrl-Alt-Del) the unit usually gets Windows to boot up properly again.

Hope this helps!
