most of my servers right now (~20 of them) are using a small ssd
for nvram and a few other things.  in that capacity, i haven't had
any failures.  nor have i seen any failures personally using them as primary
storage.  i have killed a two by messing around, but that was clearly
operator error.  (unfortunately, there were witnesses.)

if you're using a layout similar to ken's fs, the cache access pattern
should be nearly sequential.  it's the worm were ssds will come into
their own, since the access pattern is quite random.

my current worm was initialized in 2006 and i'm using just 14.4gb.
it would probablly be cost effective to switch to ssds at this point.
