Thank you for contacting the Intel community.
I’m sorry about the issue with the RAID 1.
The Intel® Rapid Storage Technology has been tested and we haven’t experience this issue in our Labs.
At this point, I strongly recommend updating the chipset driver and the BIOS, make sure they are up to date. You can download them here:

Does this happen just now or you system worked fine before and now you’re seeing this behavior?
Is it the same drive that keeps dropping out, or different ones at random?
Have you check the SATA cables? Try testing with different SATA cables.
Please let me know.
It's a brand new system, one of a couple of systems so I was able to swap out different stuff, with the same result.
a) the system is a fresh install with the latest Bios from Asus AND the latest driver set from Intel, see previous post for version.
b) See also the "bug" ID mentioned in the previous post related to the RAID1 problem.
As indicated in previous post, shutdown and powering on the system will always result in a fine system.
Restarting ( warm boot ) will result in a system with ( at least ) one of the two drives missing in the RAID1 config.
The latter could be a good indication of where to look for when fixing (b).
Considering that I am seeing quite a lot of instances with the same problem and that swapping around with hardware does not solve the problem.... and that the "known issues" of the driver set mentions sort like issues I guess there is some work to do at driver level ( or maybe chipset related recommended procedures for the BIOS ).
Looking forward to a fix for this problem!
Thank you for the information you have kindly provided, and as you mentioned above the Known Issues In 220.127.116.111 Production Version number 1804327901, this hopefully will be fix on the next released versions, hopefully it will be soon but we are aware of the problem.
We will appreciate your patience and you time creating this post.
I am having a similar issue in 2 Asus servers TS300-E9/PS4 C236 chipset. I have 2 RAID1 SSD 512GB Adata (OS) and 2 x RAID WD 1TB Red for Data. BIOS, Chipset driver are up to date. On both the servers that were online for a few weeks the 2nd SSD from RAID1 just simply unplugs and RAID becomes degraded. Tested the SSDs and they are all ok.
should I consider this a problem with 18.104.22.1681? Will downgrading to any other version solve this issue?
Did you have this problem before with a previous version? If so, I suggest you to downgrade to the previous version that it was working for you.
