ATTO ExpressPro-Tools Disk Benchmark

ATTO ExpressPro Disk Benchmark is a configurable utility that not only benchmarks but can be used to tune the disk performance for applications. In our test, we selected drive F (Seagate 80G SATA) and runs in Direct I/O mode. To simulate real world applications, we chose overlapped I/O. The graph below shows that benchmarks it reaches a read/write of 42MB/s on both controllers. It is difficult to differentiate between the two.

From my observation from the data obtained while running the tests, SiliconImage Sil3112 manages to hit a high or 28MB/s in 4K blocks in reading while the Promise PDC 20375 seems slower. In terms of writing, the Promise controller seems to have a better edge.

Depending on the kind of applications you will be using both seems to have pretty good results.
