HDTune Pro Results
HD Tune Pro is a complete hard disk benchmarking, status and erasing utility by EFD Software. Our testing procedure involved running both the read and write benchmark tests on each of the RAID configurations with screen shots of the results being taken at the end of each benchmark run. The results can be seen below:
Array 1 - Adaptec RAID 2405 + 2x Seagate Barracuda ES.2
Array 2 - Intel Matrix RAID ICH9R + 2x Western Digital Velociraptor
Array 3 - Adaptec RAID 2405 + 2x Western Digital Velociraptor
Starting off by comparing Array1 and Array2 we can see that the Velociraptor drives teamed with the Intel Matrix controller have a clear advantage over the Adaptec + Seagate ES.2 combination in both the Read and Write results. This is undoubtedly because the Seagate drives, despite being SAS, cannot keep up with the sheer performance of the 10,000RPM Velociraptors. Interestingly however, Array1 totally trounces Array2 when it comes to Burst rate, managing a 100MB/s+ increase. This possibly shows that the Intel Matrix controller is acting as a bottleneck when throughput goes beyond 200MB/s.
