It is a sensitive thing when 40 other guys depend on it.
You don't have much time to fix bugs in kernel. Your
mission is to let the users work. So you cut corners.

Yeah. I had to make do with a Compaq 5300 controller and
StorageWorks enclosures with 72 GB disks. Of course LVM
is a must to slice the RAID into a boot, swap, root and
data volumes. So if the PC burns I can just plug the whole
box into another PC. It rocks a lot faster if you can
stripe-n-mirror but I had to fall back to RAID-5 because
a) the people needed more place than speed and b) it is
still far faster than a non-mirrorred stripe I made with
fast IDE drives. And besides, I switched to reiserfs -
lot of performance gains in directory manipulation
