What's a good free open source hard drive benchmark? [closed]

After a quick search on Freshmeat I found nothing. Anybody know of a good utility?

I normally use time (dd if=/dev/zero of=newfile ...) to test write speed and hdparm -t to test read speed.

Thanks.

Solution 1:

Take a look at bonnie and bonnie++, they will give you pretty much information.

Solution 2:

You can also take a look at IOZone. Its a command line tool that runs under many operating systems and should be available to install with your standard package tools.

From their website:

The benchmark tests file I/O performance for the following operations: Read, write, re-read, re-write, read backwards, read strided, fread, fwrite, random read, pread ,mmap, aio_read, aio_write
