IDE Block Mode

 






Business Disk WinMark 99

  Enabled Disabled
Business Disk WinMarks 4890.0 4806.7

As expected, IDE Block Mode improved the performance of the hard disk in the Business Disk WinMark 99 tests. However, the difference is only 83.3 WinMarks or approx. 1.7% over the disabled mode. That's rather insignificant although the results were consistent. One would have expected a performance boost of several orders in magnitude, right? After all, it appears that up to 128X more data can be transferred per interrupt with this feature than without.

 

High-End Disk WinMark 99

  Enabled Disabled
High-End Disk WinMarks 13000 13000

In the high-end disk tests, both the enabled and disabled modes scored equally well. So, it begs the question, why doesn't IDE Block Mode improve performance here?

 

WinBench 99 Disk Tests (Details)

  Enabled Disabled
AVS/Express 3.4 9176.7 9220.0
FrontPage 98 55833.3 55666.7
MicroStation SE 15033.3 15066.7
Photoshop 4.0 6673.3 6686.7
Premiere 4.2 12400.0 12400.0
Sound Forge 4.0 19900.0 20066.7
Visual C++ 5.0 15200.0 15200.0

Although the results looked mixed with the Disabled mode having the upper hand in most cases, both modes actually scored about the same. With minor deviations aside, of course. Surprising, isn't it? Now, let's check out a real world test.

 

Winstone 99

  Enabled Disabled
Winstone Units 24.7 24.6

In this real world benchmark of office applications, the IDE Block Mode feature barely improved the performance of the whole system. It only registered an increase of 0.1 Winstone unit which is about 0.4% faster than the disabled mode.
