This answer might be out here, so if it is, I apologize, I've been looking, but not sure how to ask the question to find the answers without looking through 1x1 to find it.
I have a Z370 motherboard which supports Optane. I am putting in some Optane for use on a secondary storage device - HDD, non-raid (to help speed it up). The BIOS has two options: AHCI or Intel Rapid Storage Technology Premium w/ Optane Support (RAID). From what I have read, I will have to enable the RST w/Optane (RAID) option which I have always avoided RAID options since I don't use RAID in my desktop/workstation setups, so that in the event of any issues, I can take disks out of one machine and move them to another, take images of whole disks, etc... Again, more reading has suggested that the RST Premium/RST updated software options with RAID also handle AHCI functions, but I am not sure to what degree that applies. Let me break it down a bit more:
Z370 system, RST Premium enabled in BIOS, 32GB Optane, 1x 500GB NVMe Boot drive, 2x 8TB HDD, 1x 512GB SSD. I intend to use the Optane on one of the 8TB drives. I am not using RAID on any of the disks and had/have no intention to. I wanted Optane to speed up operations on one of the 8TB disks that I do most of my work, but was hoping that ALL of the disks, even though the BIOS/Intel Controller is configured for RAID, can be removed and placed into another machine as I see the need (as a data drive, not to boot to) without needing compatible RAID solutions on the destination system (i.e. port to Linux for imaging, port to another Windows machine for reading data files, fixing problems, etc).
That's kind of a hodge-podge there of info and might leave some scratching their heads as what it is that I am doing with my equipment (and argument for another time)... What I am trying to find out, is... FINALLY the QUESTIONS ---
Question 1) If I enable the IRST Premium (RAID) option, just for the sole purpose of using Optane on 1x 8TB HDD, have I pigeon holed, or rather, restricted these disks (512NVMe, 512SSD, 2x8TB HDD) to only be 'easily' viewable/usable on the Z370 system I have them installed on with IRST (RAID), OR could it be like when I use AHCI in a system, that even though I am configured for IRST Premium (RAID) I can still port these disks around to other systems in non-RAID configurations (AHCI) - - I know I can't boot to these disks on another system, and don't want to, just want to attach them as a secondary or data drive as needed for whatever crazy reason I wish to?
Question 2) If, like AHCI, I can move the disks around - do I have to handle the 8TB assigned to the Optane specially? In otherwords, in my Z370 system, 8TB x Optane together are happy. If I take JUST the 8TB out of the Z370 system and place JUST the 8TB (without the Optane) into another non-RAID system configured for AHCI, will I be able to read/write to that drive there (and/or use it, minus the Optane boost of course) and with/without IRST (any version/flavor premium, non premium, no RST, Yes RST - hoping you get the idea)?
Example: System 1) Z370, IRST Premium (RAID), no disks configured AS RAID --- 1x NVMe boot device, 1x 8TB HDD with Optane enable boost, 1x 8TB HDD and 1x512GB SSD non-Optane boosted
System 2) AHCI/HBA Avago adapter (non-raid mode, firmware flashed for HBA only), or AHCI onboard interfaces, or M.2/NVMe slots...
With regards to question 1 and 2:
* take my 1x 8TB Optane boosted disk out of System 1 (just the 8TB alone, leaving the Optane behind in System 1 and hook it up/use it on System 2 as is (not reformatting, want access to the data as it was pulled from System 1?
* take my 1x 8TB, 1x 512GB SSD, or 1x 512GB NVMe out of system 1 and transfer it to system 2 and hook it up for use on system 2 without reformatting, want access to the data as it was pulled from System 1?
