Disk Benchmark Tool

[Ben Clewett]

Dear List,

I am after a tool which benchmarks a file system in the same way that a 
MySql InnoDB system is likely to access it.

That is, small random reads and writes in a very large file.

For instance, the tool 'bonnie++' is no good for this as is concentrates 
too much on sequential read and write.

If any members can suggest what might be appropriate, I would be 
interested in knowing :)

Regards,

Ben Clewett.
