wondering what the benefits are of installing MEI and / or RST drivers from intel on a new system like a z390 board with an nvme drive, if any?
MEI seems to have some virtualization / remote desktop features from what I can tell, but also supposedly improves chipset performance/system performance on intel systems, true or false?
also interested in RST and what its good for if good at all, for a newer motherboard with a nvme drive for example, havent really looked into either of these until now,
thanks for any help 
@alexander86 :
The necessity of well developed and up-to-date drivers, which supports all available features of the related devices, is even greater for modern chipsets than for old ones.
These are my answers regarding the Intel RST drivers:
1. As long as you are running your SSDs/HDDs, which are connected to any Intel SATA port, in AHCI mode, you can avoid the installation of any Intel RST driver and use the generic MS AHCI driver instead. Disadvantage: You may get a much worse performance.
2. If your Intel SATA connected Disk Drive(s) should run in RAID mode, you have to install an Intel RST driver. Otherwise the OS would not even detect your SATA connected HDDs/SSDs.
Since the Intel Management Engine Interface (MEI) drivers don’t belong to the storage drivers, you should post your question into >this< much better matching Sub-Forum. Our expert there is plutomaniac.
thanks @Fernando !
and in my case which is nvme m.2 drive and not sata drive, there is no need at all for RST driver correct? only the (for example) open fabrics nvme driver is needed, right?
(open fabrics driver seems to give best performance overall vs windows 10 native/inbox nvme driver)
its single nvme disk also not RAID btw,
I will check in the MEI forum for my question about MEI
thanks again !
