In FrontPage the buffer size doesn’t matter at all. In fact, I do not see any tendencies here: it seems to be more of a controller test rather than a HDD test.
Microstation indicated that ATA models with 8MB buffer do much better here. They outpaced their 2MB counterparts by more than 22%. SerialATA models turned out to be in between.
And for Photoshop the physical features of the drives are much more important. Therefore, the laurels were won by the models with the shortest average access time, and Barracuda ATA V lost because of its relatively low data transfer rate to and from the platters.
Another Adobe product is also very dependent on the read and write speeds, although the buffer size is also important here.
Well, it seems to me that the SoundForge results are primarily dependent on the stars. At least I have no reasonable explanation of the 20% performance difference between almost identical Barracuda 7200.7 Serial ATA drives. Nevertheless, I have every right to state that Serial ATA drives are the winners here. I would also like to stress the almost 20% advantage of the Barracuda 7200.7 Plus solution over the models with 2MB buffer.
