Fake is far superior to hardware.
Of course it is :-)
Just have a battery die on your hardware card and drop from write-back to write-through... and then find out your battery was discontinued 3 years ago. Now you have a hardware specific RAID install that can no longer benefit from the hardware write-back performance at all... Though, unless you are saturating whatever your setup is -- it really doesn't matter.
You don't need selling me software raid - but I prefer true software raid. The disadvantage is you can not double boot to Windows. But can I set up an UEFI system with a mdadm driven root device as RAID1? Not that dramatic with TW as standalone machine nevertheless I wondered.
Theoretically, with Windows you should be able to boot just fine, it sees only "one" disk. The firmware should provide read access to the disk, including of course reading the duplicated EFI partition. After booting, the windows driver would add write support. Linux may do the same if that particular firmware is supported. But don't ask me, I never dared to try.
And, supplement, "provided that I am using only SSD for root. (Talking here about a standard installation with BTRFS, non encrypted and not LVM.
So the issues, if there are, you are going to have with mirroring the UEFI part.
I don't see why - talking of fake raid. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
