Iometer is the I/O measurement tool. And it's free. From the website:
Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation and announced at the Intel Developers Forum (IDF) on February 17, 1998 - since then it got wide spread within the industry.
Meanwhile Intel has discontinued to work on Iometer and it was given to the Open Source Development Lab (OSDL). In November 2001, a project was registered at SourceForge.net and an initial drop was provided. Since the relaunch in February 2003, the project is driven by an international group of individuals who are continuesly improving, porting and extend the product.
The tool (Iometer and Dynamo executable) is distributed under the terms of the Intel Open Source License. The iomtr_kstat kernel module as well as other future independent components are distributed under the terms of the GNU Public License.
You said you'd like pretty graphs for your blog. In my use of IOMeter, I've never seen it produce a graph. However, it is possible that I overlooked an existing feature.

Iometer 是 I/O 测量工具。而且它是免费的。来自网站：

您说过您希望为您的博客提供漂亮的图表。在我使用 IOMeter 时，我从未见过它生成图表。然而，我可能忽略了一个现有的功能。
或者，（从其网站的外观来看）iozone 可能会为您提供图表：
http://www.iozone.org/
然而，iozone 可能仅收集了数据用于创建其网站上显示的图表。
无论如何，这仍然是 I/O 基准测试的另一种选择。

Alternatively, (from the look of its website) iozone might give you graphs:
http://www.iozone.org/
Yet, it could be that iozone only collected the data used to create those graphs shown on its web site.
Regardless, this is still another option for I/O Benchmarking.
