Usually a product has to be outdated and outperformed before it gets replaced, but not those in LSI's portfolio.

HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.

As you can see we are analyzing from a pretty deep well today. We'll start out with the obvious, Fast Path enabled gives us a nice performance increase when comparing equal block sizes. This is a sequential read test so the larger stripe sizes performed better than the smaller sizes. Last but not least, RAID 5 and RAID 6 didn't have a very large performance penalty at all with the controller running eight drives.

In the sequential write test Fast Path once again gave us a nice boost. In the larger stripe sizes the difference was sometimes over 300 MB/s (average write). The smaller strip sizes couldn't keep up with the larger stripe sizes; observe the difference between 64kb vs. 512kb and 1MB.
