Performance in WinBench 99

We used the good old WinBench 99 for our low-level tests.

The next diagram compares the HDDs in terms of speed at the beginning and end of the full-capacity partitions created on them.

The three generations of 10,000rpm drives have ranked up in a logical way: each newer generation is about 50% faster than the previous one. What is more important, the newest generation with 150GB platters is about as fast as modern 3.5-inch drives with a spindle rotation speed of 7200rpm. Thus, we can expect them to be comparable when it comes to sequential reading/writing. The compact drives even look preferable as they have a smaller difference between the minimum and maximum speed: about 50% rather than 100% as usual. This is due to the smaller diameter of their platters.

The only 15,000rpm drive in this review has an interesting position. It is of course faster than the 10,000rpm drives with the same recording density but also faster than the models with two times its recording density. Thus, it is only inferior to the newer Hitachi C10K300. It is sad we don’t have a new-generation 15,000rpm drive for this review. It would be interesting to see if the newest 15,000rpm drives are still the fastest of all.
