Do you have any basis upon which to cast doubt on the development of
FakeRAID drivers?
Anyway, this wasn't the issue that I've seen raised.
The argument that I've seen (and I've fallen vistim of this because a
purchasing manager once dropped a letter from the end of a RAID card
model) is "can you be sure if a RAID card or a motherboard is replaced
that you'll be able to plug in your disks and boot without a hitch?" I
prefer mdadm, whether this is an issue or not.
