They totally missed "mainly write" applications which most of my  
applications are. Reads in a OLTP setup are typically coming from a  
cache (or, like in our case an index like Solr) while writes go  
through ... So you might get some decent IO from the SSD when the  
database just started up without caches filled, but as long as your  
cache hit ratio is good, it doesn't matter anymore after a couple of  
minutes.

Nevertheless it's an interesting development.
