We built a RAID0 array with two 160 GB hard disk drives and compared the performance of this system against the performance achieved with a RAID0 array using the same drives but controlled by ICH9R south bridge chip from the motherboard we were using (ASUS P5K-E/WiFi-AP, which is based on Intel P35 chipset), using the recommended stripe size, 128 KB. We also compared the results with the performance of a single drive installed on our PC, in order to see how much performance gain you should expect to achieve with a RAID0 system.
During our tests we used the configuration listed below.
We adopted a 3% error margin. So, performance differences below 3% cannot be considered meaningful. In other words, products where the performance difference is below 3% must be considered as having similar performance.
