Also, how many folks are using hardware raid, at all, these days?  I
discovered several years ago that properly configured software RAID is much
faster, and quite often easier to manage, than hardware RAID.  I have a
whole drawer full of hardware RAID controllers that I no longer use.

Even without ZFS, LVM on top of MD raid (on Linux, or course), is pretty
darned easy.  Only caveat being that you can't boot from RAID-5+, but
that's easily remedied with a RAID-1 /boot.

My blathering:

The really big advantage of software RAID is that you never need to go
searching for some now-obscure RAID card to get at your data (or level the
array and start from scratch and dump tapes). Plug it in a new machine, put on
the same (or compatible) OS, reattach the arrays and you're good to go.
