Performance in WinBench99
With the help of ZD WinBench99 we can evaluate the performance of our testing participants in a few typical applications. Even though some of these applications have already become outdated and the data volumes involved into the testing process are too small for today, the results obtained in WinBench tests are still pretty illustrative and useful.
At first let’s compare the results obtained in FAT32 file system.
In Business Winmark the HDDs ran very close to one another and their results fully correspond to their positioning in the market. Larger buffer allows improving the performance quite tangibly. Barracuda 7200.7 Plus most probably managed to defeat Barracuda 7200.,7 SerialATA because of the differences in controller drivers for Promise Ultra133/TX2 and SATA150/TX2.
High-End WinMark showed a slightly different picture. The previous generation represented by Barracuda SATA V rolls back to almost the very last position, and the performance boost granted by a larger cache-buffer makes 9%, which is not as high as we expected, actually. Let’s analyze some discrete results to find answers to all these questions.
Hm, this is nice. In AVS the results of all HDDs look like a bunch of neat stairs, though you still can distinguish between the groups. It looks a sif a lot of factors are involved in the game here. ATA HDDs with 8MB buffer are ahead of all, outperforming the models with 2MB buffer by up to 18% in some cases. SerialATA Barracuda drives of both generations perform very closely, which once again proves how little the “raw” speed (the data transfer rate to and from the platters) matters for the actual performance of the drives.
