you could easily achieve double, triple, or even quadruple co-located redundancy for far less than what s3 would charge for 40TB. Before anyone replies about needing a "24/7 sysadmin", if you are running stuff at this scale: A) You already have a sysdmin, or somebody competent enough to do the setup/maintenance work. Running off s3 doesn't magically mean you never need deal with sysadmin issues. B) Rack providers will swap out hardware if you put in a ticket, so you can provide multi-regional redundancy for much much much cheaper than amazon would charge you ($60000*2 for 2 regions gets expensive fast)
