I'm a bit concerned with usage-dependent failures. Presumably, two SDDs in a RAID-1 configuration are weared down in the same way, and it would be rather inconvenient if they failed at the same point. With hard disks, this doesn't seem to happen; even bad batches fail pretty much randomly. -- Florian Weimer <fwei...@bfk.de> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99 -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
