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
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
I don't see why - talking of fake raid.
