i tried to rtfm, but found no clue how to do this:

i'm setting up a server where i will use three identical hard drives,
it was trivia to figure out how to strip two drives, but i want to
mirror to the third...

is it possible?

sure i could crontab some daily process, but i would rather do it on the
fly, since stripping _is_ a risk if either of the drives blows up...

i am planning to throw adaptec 3940UW into the machine and have the
two drives on one channel and the mirroring one on the other, or should
i have the stripping drives on different channels?

or does anyone have suggestions how to drive the machine to the edge? =)

(p166, 96-128 ram, ga586hx512 board, 3940uw, smc 10/100 ether)

also, any recommendations which fast wide scsi2 and ultra wide scsi drives
gives the best performance/reliability... i was thinking to use seagate
barracuda drives... opinions? i personally would use something else, but...

i'm bulding the machine in a week or something...

oh yes, i would've loved to use the HP C1553 DAT autoloader, but i doubt
FreeBSD 2.1.5 (this is what i will use) supports it? so, i guess i have
to do with HP C1533... right?
