I like their approach...ddr ram + raid sanity backup + super reliable
power system. Their prices are on jupiter (and i dont mean jupiter,
fl) but hopefully there will be some competition and the invetible
decline in prices. When prices drop from the current 1-2k$/Gb to a
more realistic 250$/Gb there will be no reason not to throw one into a
server. You could already make a case for an entry level one to
handle the WAL and perhaps a few key tables/indexes, particularly ones
that are frequenct vacuum targets.

ddr approach is much faster than flash nvram inherintly and has a
virtually unlimited duty cycle. My prediction is that by 2010 SSD
will be relatively commonplace in the server market, barring some
rediculous goverment intervention (patentes, etc).
