Optane 905P SSD poor performance in 4k1Q1T test

[RoyalGriffin]

Hello!

My SSD shows 95MBytes/s maximum result of 4kbytes 1Q1T operations in CrystalDiskMark.

System is Xeon 2xE5-2667v2, DDR3 1333 256GB.

May this problem be with Optane or it seems to limitations of my system (too old)?

Thank you

Hello, RoyalGriffin.

Thank you for posting on the Intel Community Support forums.

I received your thread regarding the Intel Optane SSD performance, I will be glad to assist you.

Please let me know the following:

1. Is the Intel NVMe driver installed?

- Download: https://www.intel.com/content/www/us/en/download/19172/client-nvme-microsoft-windows-drivers-for-intel-ssds.html

- Try installing the driver and check if there are any changes.

2. Please follow the Evaluation Guide for Client Intel® Optane™ SSDs available below:

- https://www.intel.com/content/www/us/en/support/articles/000025989/memory-and-storage.html

- This document provides guidance on system and drive preparation along with examples.

I will follow up on October 14th in case additional time is required.

Hello, Bruce!

Yes, the reason was the insufficient amount of performance of one core when testing 4k1Q1T. If I use 32 cores (threads), then the performance tends to 500,000 operations and the speed to 2 GB/s. The Evaluation Guide was useful for correct test.

Thank you
