vRoC big trouble, high response time only on Raid5


same problem like...

I have:

• Gigabyte C246M-WU4
• 4x 16 GB ECC
• Intel E-2276G
• 1x 250 GB Kingston A2000 (in the future 2x as Raid 1 planed)
• 5x 3 TB WD30EFRX as Raid 5 (Intel vRoC, Version / ????)
• 1x 8 TB ST8000AS0002
• 1x 250 GB MK2546GSX
• Windows 10 Pro 64 20H2 Build 19042.746, all updates and drivers 


Only the Raid 5 is extrem slow if any access on it!
There are huge average response times!

The same work loads on the other single drives makes no problem.

i need support from specialist ASAP please!

Hello, @ACX_Com.


Thank you for contacting Intel Community Support.


I received your thread regarding the RAID 5 performance issues on your Intel VROC configuration, I will be glad to assist you.


After reviewing the details you have provided I would like to recommend contacting your OEM or motherboard manufacturer since, according to the list of the latest drivers available for your motherboard, you should be working with either Intel RST (17.X) or Intel RSTe (5.X) depending on your operating system (


I would assume that for your current configuration involving SATA HDDs and Windows 10 Pro, it would be better to work with the latest Intel RST version from your manufacturer instead of the Intel VROC version you installed, but the best option is to check with the manufacturer as you will need to continue working with them in case the issue persists.


If you have any other questions or concerns, please let me know, but if that is not the case, I will proceed to close the thread on January 27th.


Best regards,

Hello, ACX_Com.


Thank you very much for waiting.


We have been reviewing your case and the details of your configuration. 


Knowing that you have experienced the same issue with the three solutions you have tested (VROC, RSTe, and RST), at this point the best option is to work with the motherboard manufacturer directly for further troubleshooting and guidance, especially since you still need to identify the appropriate driver and version for your current configuration.


If they determine this is driver-related, the platform manufacturer will then work with us to resolve any issues as appropriate.


I understand you have already contacted them and you are currently waiting for a response; I will proceed to close the thread since further assistance is to be provided by the system manufacturer/OEM.


Please do not hesitate in contacting us back by opening a new thread if you need assistance with any other Intel products as this thread will no longer be monitored.


Best regards,
