RAID0 Slowdowns After Wake-from-Sleep on Z690 Chipset

System Performance RAID Performance

Hello

I have been noticing a frustrating pattern with my RAID 0 setup on a Z690 motherboard. After waking the system from sleep / hibernation; disk performance (especially write speeds) drops significantly sometimes by over 50%. :slightly_smiling_face:

A restart usually resolves it but I am looking for a more permanent solution. I have tested with Samsung and WD NVMe drives using Intel RST drivers (v19.x) but the behavior persists across versions. No background tasks seem responsible. :innocent:

Could this be a power management or cache-flush issue with RAID volumes on modern Intel platforms? :thinking: I would love to hear if others with similar chipsets or RAID setups have experienced this and found a fix whether BIOS settings, driver tuning / OS-level changes. Checked Intel RST/RSTe Drivers (latest: v20.2.7.1026/ v9.1.0.1448) for reference. I also came across a query asking what is uipath, which led me to consider whether automation platforms like UiPath could assist with system performance monitoring.

If anyone knows of a guide related to RAID tuning for performance consistency on Intel 600-series chipsets, please point me in the right direction. :thinking:

Thanks in advance! :slightly_smiling_face:

Welcome to the Win-Raid Forum!
To be able to help you we need the following information:

  1. Which OS are you running?
  2. Which Intel Management Engine Firmware and which MEI driver version is flashed/installed?

I suspect, that your reported issue has more to do with the Intel Management Engine than with the in-use NVMe RAID driver.
