Win10 Pro Raid 1+0 Write Back Crash with Intel RST

[LMand1]

Greetings! About 6 months ago my previous Windows 10 Rig ran into issues when I had Write Back enabled on my raid 10 array using Intel's RST, during heavy download traffic, or any download above 5 megabits my system would hang and become unresponsive. Consequently, that unit was built around a problematic Asus Maximus 7 Formula motherboard. I was able to remedy the issue on that rig by simply not using write back. Given that motherboard was flaky I RMA'ed it to ASUS but have since built a brand new rig with an MSI X299 Gaming Pro AC motherboard and migrated my previous data from the old raid to a new Raid 10. I'm also booting off a Samsung 960 EVO. The build has gone smoothly until, on the new unit I enabled Write Back on the Raid array as well. The exact same symptoms have arrived. During heavy downloading with any of the 3 LAN devices, or any externally controlled USB Lan Adapter the system will become unresponsive. I'm using a complete different set of hardware and Windows 10 Pro was a clean install on the new build. I'm at a total loss as to why this would be occurring. Anecdotally I can't remember which Windows 10 build I was running on the previous system when I noticed that it was working ok, then went to not working properly. Additionally, the previous unit was an upgrade from Windows 7 Ultimate to Windows 10 Pro. After the initial upgrade the RAID behaved beautifully with Write Back enabled for about 12 months until it didn't about 6 months ago.

Thank You in advance for any assistance anyone can render.

So far I've had the drivers in production with write back enabled on my main office PC for about a 5 days now. I can report I've tested heavy download and file operations with no issue. It looks like this driver set may have remedied the problem with RAID10. I will let you know next week as well.

Best,

Landon
