that's expected with castoffs like this, and isn't in and of itself
hateful.  what wasn't expected was the 32768MB logical device limit and
the four hour parity initialization, which are both firmware
limitations.  firmware is just a fancy name for software that executes
on a processor other than the main CPU(s).

the software RAID option, necessary because toor knows at least one of
these drives will eventually fail, has the hatable read/modify/write
hole: http://blogs.sun.com/roller/page/bonwick?entry=raid_z .

since when did this list include a restriction that the source of
software hate be non-self-inflicted?  (:
