Is a home computer or a server/workstation? Can you (or your company)
afford a disk going down or data loss?

Good. Remember that raid does not prevent from the human error factor ;-)

Fake-raid (firmware+bios raid) is more used on dual-boot systems (windows
and linux) when windows OS was configured for using a raid setup. In such
cases, one has no other chance and keep the fake-raid in order to use
linux :-(
But if you are not "binded" to windows, better go with "md" (software
linux) that is far more flexible and very well supported in linux.
Although I'm not sure if today md setup allows booting from raid
partition or still boot manager has to be dropped off the raid volume :-?
