So at the moment we are using this machine as our primary database server: http://www.hetzner.de/en/hosting/produkte_rootserver/eq9/ Sadly, our hoster is not offering advanced disk setup. Now we have two options 1. buying a server on our own and renting a co-location. I fear we do not know enough about hardware to vote for this option. I think for co-locating your own server one should have more knowledge about hardware. 2. renting a server from a hoster with an advanced disk setup. Can anybody recommend a good hosting solution in germany with a good disk setup for postgresql? kind regards Janning -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
