Hello all & Bonjour a tous 
i have few questions about the Intel Rapide Storage in raid and the OROM update and integration bios.
i have the Asus Maximus XI Extreme (intel chipset Z390) and i will install on my system only 2 NVMe (2x Samsung 970 Pro of 1GB). i will not use an normal hard drive or ssd on this system.
1- is here a benefict to install those 2 NVMe in raid 0 ? (i even dont know if we can lol (i was on my very old motherboard 2 normal ssd in raid 0)).
2- do i need to use the Intel rapide storage for those NVMe in Raid 0 ?
3- if yes can you please tell me how i can Update the OROM ? is always like in past ? mean we have to update this orom rapid storage by making modification on each new motherboard bios ? and using to uppload this bios with only the usb en flashback procedure ?
4- if answer of the question 3 is Yes, can please tell me how to do that ? in past it was a tutorial but i never succed to do it then i was asking an person you know who was making those upsade for us, but he stop doing that since this old time… 
thank you
Yes, as with all kind of Intel RAID0 arrays there is a benefit regarding the speed of writing and reading big sized files.
Yes.
4 x yes, but there is no reason to change the Intel RST BIOS module(s) after having created the RAID array and found the best performing Intel RST RAID driver/BIOS module combination.
It is very easy by letting do it th UBU tool. You can decide, which Intel RST RAID BIOS module should be inserted into the BIOS (for details look >here<).
oh Fernado ! hope you are fine aftre all this years
1- onthiis motherboard the only way to update the biso is by usb flash dongle ? not by asus update or other software from asus ?
2- i dont understood what you say on answer 3 : "" there is no reason to change the Intel RST BIOS module(s) after having created the RAID array and found the best performing Intel RST RAID driver/BIOS module combination""
If i am not wrong i must check this after every OROM update right ? and driver too ? for this i must always update my old asus bios or the new one with the new RST OROM to check that ? Or is another way like an Official post here where people test each version and give there feedback. if this those feedback exist, the results will be the same on the same chipset like this exemple tyhe Z390 ? or depend on the brand like assus msi they can have different reslut and react better depend of RST OROM version ?
3- for your answer on the question 4 i just need to follow exactly the steps on the link you provide ? or adapt it to my bios ormotherboard ? etc?
thank you
EDIT: do i have to be careful to update with UBU Tool some area, driver, orom, firmware, cpu etc… on this last motherboard Asus Maximus XI Extreme (intel chipset Z390) who is not yet toaly avaible on the market ? oh i forget : they are 2 lan port on this motherboard the intel 1G and the Aquantia AQtion Network Adapter 5G… Or i can just update all without problem ? ^^
i had an very old motherboard and i am totaly lost now but i dont want to destroy this motherboard who cost me an kidney and the I9 9900K the second kidney ^^
@Fraizer :
General advices:
- Each flashing procedure of a mainboard BIOS is risky, especially when the BIOS has been modified by the user himself. Before you are going to flash such BIOS, you should be sure, that the expected benefit is worth the risk of a bricked mainboard.
Examples:
a) An update of any LAN OROM/EFI BIOS module is useless unless you are using the Wake-on-LAN feature.
b) Updates of the RAID OROM/EFI modules only make sense for systems, whose SATA Controller is running in RAID mode. - Don’t touch the BIOS of a brandnew mainboard with a brandnew chipset, unless you have a severe problem, which is caused by a wrong/not matching BIOS module.
Reason: The BIOS of your mainboard is still under devopment by the manufacturer (here: ASUS). Furthermore you can expect several new BIOS versions from ASUS within the next 12 months.
If you want to flash a modded BIOS, you have to put the BIOS onto an USB flash drive and to use the ASUS Flashback feature.
As written above, I do not recommend to update the Intel RAID modules, unless you are absolutely sure, which Intel RAID storage driver version is the best for your system and your specific kind of PC work. Then you can update/downgrade the Intel RAID ROM/EFI module to get a matching RAID driver/BIOS module combination.
Yes!
Yes, absolutely. Before you are going update sensitive modules like the CPU Microcodes, I recommend to wait until ASUS has finished its task to optimize the CPU Microcodes of their original BIOS.
thank you
Fernando is a link or an area on your foorum where people test every new version in orom with combinaison with drivers to show who is the best one about speed etc?? the orom new version it fixing bug too not only the speed right ?
when you said : ““Yes, absolutely. Before you are going update sensitive modules like the CPU Microcodes, I recommend to wait until ASUS has finished its task to optimize the CPU Microcodes of their original BIOS.””
- you mean if update after i mod my bios with this tool i cant found back the cpu microcodes when i will update with an new asus bios noy moded ?
- about asus optimized… is mean asus will take the best cpu microcodes version for this motherboard and this not mean the last version avaible ?
- on UBU Tool it update the last stable or final microcodes right ? or ?
@Fraizer :
AFAIK I am the only one, who tested with several different Intel chipset systems, which Intel RAID driver/BIOS RAID module combination is the best. You can find >here< the results of my recent Intel RAID0 benchmark comparison tests and >here< my recommendationss for the different Intel chipset systems.
General comments:
- The RAID BIOS modules have an impact on the length of the booting time and on the functionality of the RAID array, but its effect on the performance of a RAID array is very limited. That is why the choice of the best performing Intel RAID driver is the most important step.
- Once the “best” Intel RAID driver has been found, it is very easy to choose the best matching Intel RAID ROM/EFI module for the BIOS. It is always the latest sub-version, which belongs to the same Intel RST development branch (e.g. 11.2, 13.2, 14.8, 15.5 or 16.9) as the “best” Intel RAID driver.
- The Intel RAID ROM/EFI BIOS module may have a lower version than the in-use Intel RAID driver, but should not belong to a higher RST platform (v11/12/13/14/14/16/17) than the driver does.
Your question about the CPU Microcodes has nothing to do with the topic of this thread. So you should better post such questions into >this< Sub-Forum, where the related experts are watchig and helping.
