Bonnie++ is a benchmark suite that is aimed at performing a number of simple tests of hard drive and file system performance.
Then you can decide which test is important and decide how to compare different systems after running it. I have no plans to ever have it produce a single number, because I don't think that a single number can be useful when comparing such things.
The main program tests database type access to a single file (or a set of files if you wish to test more than 1G of storage), and it tests creation, reading, and deleting of small files which can simulate the usage of programs such as Squid, INN, or Maildir format email.
