My Laptop came with an NVME drive (1TB) with an additional Optane (28 GB) modules a NVME card.
I added a second 1TB NVME drives as laptop had a spare NVME slots - it has no SATA slots.
There is a bios option to specifically switch off the VMD controller but does not seem to do anything else e.g. offer AHCI as an alternative.
I tried to install Linux and it recognised the second NVME drive and obviously has a native IRST driver equivalent but would not recognise the NVME Optane drive.
I looked in bios again, and found I could turn off the optane module and now had three drives - 2 1TB drives and a small 28 GB drive.
I could install Linux on either drive and it booted fine (the existing windows installation was not affected).
I wiped the Linux installations and turned off the vmd controller and tried again - now it would not recognise either drive. It seems my laptop does not have an AHCI mode - I guess it was disabled as I can only add nvme drives using an IRST driver?
It is interesting standard Ubuntu and Mint installers recognise NVMEs but the poxy standard Windows iso does not - I have to add it using dism (or load it at install time).
So now having turned off optane - what performance loss would I get - I could not see any obvious performance loss.
I was really surprised when I did a Macrium Reflect backup with default medium compression - 1 min 50 seconds with optane on, 1 min 40 seconds with optane off.
So far, I cannot see any benefit of having optane on, and at least one negative impact. No wonder it has been decided to abandon it going forward!
