Another measurement you might like to make would be random reads and/or writes.
Take a look at the debian package called "bonnie++" > Provides: bonnie, zcav > Description: Hard drive benchmark suite. > It is called Bonnie++ because it was based on the Bonnie program. > This program also tests performance with creating large > numbers of files.
