Fusion SSDs install on PCIe slots, so are limited by slot count. None, so far as I recall, are bootable (although Fusion has been promising that for more than a year). If you've a BCNF schema of moderate size, then any SSD as primary store is a good option; Fusion's are just even faster. If you've got the typical flatfile bloated schema, then while SSD will be faster (if you've got the $$$), PCIe is not likely to have sufficient capacity. SSD is the reason to refactor to a Dr. Coddian schema. Few have taken the opportunity. regards, Robert ---- Original message ---- >Date: Fri, 29 Apr 2011 10:24:48 -0400 >From: pgsql-performance-owner@xxxxxxxxxxxxxx (on behalf of Mark Steben <mark.steben@xxxxxxxxxxxxxxx>) >Subject: FUSION-IO io cards >To: pgsql-performance@xxxxxxxxxxxxxx > > Hi, > Had a recent conversation with a tech from this > company called FUSION-IO.
