The info/welcome message on vger.kernel.org has a pointer to this

<para>How should I benchmark my RAID devices? Are there any

<answer>
|
||||
<para>There are really a few options for benchmarking your RAID
|
||||
array, depending on what you're looking to test. RAID offers the
|
||||
greatest speed increases when there are multiple threads reading
|
||||
from the same RAID volume.</para>
|
||||
|
||||
<para>One tool specificly designed to test and show off these
|
||||
performance gains is <ulink
|
||||
url="http://tiobench.sourceforge.net/"
|
||||
type="http"><application>tiobench</application></ulink>. It uses
|
||||
multiple read and write threads on the disk, and has some pretty
|
||||
good reporting.</para>
|
||||
|
||||
<para>Another good tool to use is <ulink
|
||||
url="http://www.coker.com.au/bonnie++/"
|
||||
type="http"><application>bonnie++</application></ulink>. It
|
||||
seems to be more targeted at benchmarking single drives that at
|
||||
RAID, but still provides useful information.</para>
|
||||
|
||||
<para>One tool <emphasis>NOT</emphasis> to use is
|
||||
<application>hdparm</application>. It does not give useful
|
||||
performance numbers for any drives that I've heard about, and has
|
||||
been known to give some incredibly off-the-wall numbers as well.
|
||||
If you want to do <emphasis>real</emphasis> benchmarking, use
|
||||
one of the tools listed above.</para>
