Use /dev/null.  It is web scale, and there are good tutorials.

But seriously, there *are* cases where "blind speed" is of use.  When
loading data into a fresh database is a good time for this; if things
fall over, it may be pretty acceptable to start "from scratch" with
mkfs/initdb.

I'd:
- turn off fsync
- turn off synchronous commit
- put as much as possible onto Ramdisk/tmpfs/similar as possible
