DC P4510 sequential read performance is way below expectations

[Cliffdale89]

Hello

I have recently bought a pair of new DC P4510 U.2 drives and when I did a quick performance

check using

hdparm -tT --direct /dev/nvme0n

on Debian 11 I noticed that one drive gives just 1449.88 MB/sec while the other drive maxes out at 2590.08 MB/sec. Both drives have the same FW VDV10182 and have negotiated the same PCIe link speed (8GT/s,x4). I have also cross tested with another system and received the same results.

Should I RMA the drive in question?

Hello, Cliffdale89.

Thank you for contacting Intel® Memory and Storage support.

As we understand, you are requesting support for your Intel® SSD DC P4510 Series if we inferred correctly, we would appreciate it if you may provide us with the following information:

1- We would appreciate it if you may provide us with the system details by extracting the SSU logs.

A- Go to https://downloadcenter.intel.com/download/25293/ (for Windows*) and to https://downloadcenter.intel.com/download/26735/ (for Linux) download the software.

B- When you finish downloading it, open it.

C- Attach the file generated by the tool in your reply.

2- We would like to check the SMART attributes of your Intel® SSDs and review them to see if they show any error, using this system or another system that recognize the drives:

*Please extract the following logs by using the Intel® Memory and Storage Tool:

https://www.intel.com/content/www/us/en/download/19520/intel-memory-and-storage-tool-cli-command-lin...

- SMART attributes: intelmas show -smart -intelssd “SSD_index”.

-The SSD information using show -all command from Intel MAS CLI: intelmas show -all -intelssd “SSD_index”

A complete User Guide is available below. Replace the “SSD_index” with the actual index number of your SSD.

3- Is this drive new, or it came preinstalled with your PC?

We will follow up with you again on Thursday, the 30th of September 2021, if we do not receive an answer from you. Please, let us know if you would like to schedule a different date for the follow-up.

Hello, Cliffdale89.

Thank you for your reply.

We have been working on reviewing the logs you shared with us, and we noticed the following:

1-  The SSU logs do not reflect your Intel® SDD as connected to the system.

2-  The SMART logs are not showing any hardware issue with the SSD.

We advise you to use another tool to test your SSD performance like FIO (http://freshmeat.sourceforge.net/projects/fio) instead of the hdparm since it was designed to be used with ATA/SATA and may not provide you with accurate readings.

Please review the following public information as a reference to test your SSD:

- How to benchmark SSDs with FIO Visualizer

https://itpeernetwork.intel.com/how-to-benchmark-ssds-with-fio-visualizer/

- Evaluation Guide for Intel® Solid State Drive DC P4510 Series using Linux* Intel® Virtual RAID on CPU (Intel® VROC) with FIO*

https://www.intel.com/content/www/us/en/support/articles/000032617/memory-and-storage/ssd-software.h...

Please follow this article as a reference since it is for SSD on VROC, but it will provide you with the information necessary to run your test.

We would be looking forward to your reply in case that you need further assistance.

We will follow up with you again on Friday, the 1st of October 2021, if we do not receive an answer from you. Please, let us know if you would like to schedule a different date for the follow-up.

Best regards.
