All UltraATA/100 controllers score pretty much the same. The VIA chip is only two points behind Intel's product, which is absolutely negligible. As you can see, the data overhead of all three solutions is approximately 15%, proving that the maximum of 100 MB/s still is a theoretical value. We included the test result with VIA's 686A (old model), which is hardly capable of transferring 30 MB/s - even though this chip is supposed to support UltraATA/66. So far, this is not a disadvantage, since most hard drives do not exceed 30 MB/s. Even if they do, that only happens while sequential reading, which also occurs quite infrequently.
