That is true.  Actually, the software we are considering are 
neither database systems nor Unix tools like 'sort'.  Sorry 
for mentioning them in my original post -- they weren't 
meant to mislead any of you, but to generalize my question.

The software we are using are actually bioinformatics tools. 
 While there are many users, the user base is still tiny 
compared PostgreSQL.  So, there aren't many benchmarks that 
look into how they perform with combinations of HDDs and SSDs.

Thanks for your suggestion!
