PCMark 04

PCMark2002 had some issues with their HDD performance metrics, in almost all cases, the sequential performance was monitored higher than the most transfer rate and overall the results appeared less than shady. PCMark 04 has been completely revamped and uses a variation of Intel's IPEAK tool. There are still issues with double caching, however, of all application benchmarks currently available, it appears to be the most relevant and up to date.

We ran the ASUS P4C800E through the HDD suite using a number of different conditions, the Fujitsu MHT2060AH SA in a single drive configuration using either the built-in ICH5-R in single drive mode, the HighPoint RocketRAID 1640 and the Promise S150 TX4 in single drive mode as well as in a two drive RAID Level0 configuration. Finally, we ran the HighPoint RocketRAID 1640 controller in Level5 (four drives) with a stripe block size of 32k and 64k, respectively. As a reference, we ran the same benchmarks with the Seagate Barracuda 7200.7 on the ICH5.

What is interesting about the results above is that the MHT2060AH SA appears to work better with either the Highpoint or the Promise controller than with the ICH5, at least in single drive configuration. One of the reasons for this apparent paradox is the lack of dedicated drivers for the ICH5 in single drive configuration, Intel has only released the IAA / bus master drivers for the RAID configuration. Keep that in mind when looking at these graphs. Another interesting issue, yet expected issue is the block size dependency of the performance of the drives in the RAID5 configuration with the smaller block size resulting in better performance.

The same system configurations as above. In the XP startup benchmark the RAID Level0 with the RocketRAID controller bests the Barracuda 7200.7 with the latter running in single drive configuration

Application loading favors a faster single drive.
