If you believe comments like those at 
http://www.c0t0d0s0.org/archives/1792-Do-it-yourself-X4500.html it's 
possible to hit >2GB/s total to the 48 disks in one of the Sun X4500 
servers, which start at $24K.  May be unlikely to you, but I was reading 
there after I set one up last night, and that's a boring standard 
configuration for some Sun and Greenplum customers.

Also, that's today--by the time 8.4 is mainstream high-end machines will 
be even faster.  Wanna make a bet on how much disk throughput will be 
available as SSD disks go mainstream in the next two years?
