For RAID10, perhaps, perhaps not. It's used in enterprise for a good reason.
That said, one' speaking of higher end hardware in the RAID controller
than the usual card a consumer would acquire.

I'm running RAID5 on my Poweredges, with are dual Xeon processor models.
Good to toss data about on the network, disk IO and database
transactions, as that is what they're built to do. Not as good for
desktop video, as who in their right mind would want one of those noisy
beasts on their desk (OK, I'll plead guilty to that on a few sparse
occasions, but that was actually to work on a new baseline and save me
trips to and from the server room. Once completed, I was happy to get
that beast away from my desk!).
But, that is a different kind of hardware than most users will use. It
all depends on the hardware used and application.
That said, I've not found many inexpensive RAID cards out there
(inexpensive as under $300) for current drives. What I have found would
be of benefit on a server board, not in the average users PC turned server.
