Performance in Intel IOMeter Sequential Read and Write Patterns

During the performance tests in these patterns we check how well the HDD can cope with ordered requests with linearly growing address. The requests queue depth starts at 4 requests and then once per minute the size of the requested data block increases. The highest results in the tables below are highlighted with the blue color, the lowest results – with red color.

The Sequential Read graph shows very clearly that the controller integrated into Intel ICH5 performs best of all. VIA VT6212 outperforms it just slightly on small data blocks, but loses to the rival as soon as the data block size increases. At the same time, VIA VT6212 controller seems to be more efficient than its predecessor – VT6202.

The Sequential Write graph is very similar to the previous one. The general picture remained unchanged, but VIA VT6212 got much closer to Intel ICH5. At the same time, the gap between VIA products has grown significantly bigger as we shifted to large data blocks.
