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.

Robert
