[OSM-dev] osm2pgsql slim mode, postgis, and hard disk spindles

[Sergiusz Pawlowicz]

yes, it works much faster:

less secure:

# mdadm --create /dev/md0 --raid-level=0 --raid-devices=3 /dev/sdb
/dev/sdc /dev/sdd

more secure but still efficient especially for writing:

# mdadm --create /dev/md0 --raid-level=5 --raid-devices=3 /dev/sdb
/dev/sdc /dev/sdd
