The Atlas V continues to exercise its proficiency in WinBench99 over the 18XL in tests run on our older testbed. In Windows 95 we find the Seagate drive trailing Quantum's offering by a margins of 12% and 10% respectively in the Business and High-End WinMarks.

Differences in WinMark scores running under NT are remarkably similar to the new-testbed results despite the different operating system and hardware. Here again the 'Cuda falls behind the Atlas by 7% in the Business test and 15% in the High-End.

ThreadMark scores exhibit large gaps. Seagate's unit doesn't fare well in comparison to the Quantum, lagging by margins of up to 33%.
