heh. you are likely in for a rude surprise.

didn't check the archives?

There are a few long, rambling posts by me in there. Read 'em. Lot of
other people had some good wisdom there, too. And a few turkeys. You
get to decide which are which. (hint: I'm probably a turkey. :)

General answer: no.
I'm suspicious that if teamed up with ccd, it might be possible to do
some nifty stuff with a software-based (i.e., el-cheapo) (pseudo-)RAID
card. HOWEVER, until I actually verify that, you are on your own. And
no, it isn't brainless and turnkey. Hint: standard IDE interfaces and
BIOS won't boot if the PRIMARY drive is dead...
