Winbench 99 Version 2
Weve had some concerns about the age of Winbench 99, but in our testing here, the results seem pretty consistent. In our experience, the DiamondMax Plus 9 sports one of the highest raw transfer rates of any ATA hard drive, while the 7200 rpm Barracuda ATA V has one of the lowest. So it stands to reason that the Maxtor external drive should perform better than our homebrew external drive.
Interestingly, the 5000DV posts a higher transfer rate at the beginning of the drive using the FireWire interface than USB 2.0. As we reach the end of the drive, the results are pretty similar for all three Maxtor variants -- indicating that slower transfer rates available at the end of the drive dont saturate any of the three interfaces and software stack.
Were not quite sure why Winbench would report a substantially slower access time for the external drive, though it could be simply latency issues with the FireWire or USB to ATAPI bridging controllers. The differences in CPU utilization are also interesting. In the Maxtor drive, the 1394 connection seems slightly more efficient than the USB controller. At first blush, the Barracuda ATA V inside the Belkin enclosure might seem more efficient -- except that it doesnt move as much data to begin with.
