Business Winstone 2002 and Multimedia CC Winstone 2003 Test Results
In our real world applications tests, things suddenly become less clear. The Barracuda drive still lags behind, but the difference in Business Winstone is about 10%, while the difference in CC Winstone is negligible. Again, the older WD1000JB staggers in behind the newer generation.
All of the disks ran relatively warm, but not nearly as hot as some of their predecessors. Its clear that fluid-damped bearing technology has progressed from the early days when some drives with fluid bearings would actually run quite warm. Still, if you were running a RAID array, youd want to have adequate cooling.
Interestingly, the IBM and Western Digital drives were the quietest when running at full bore -- roughly 5dB above ambient. The Barracuda drive was surprisingly noisy, given the idle noise spec, but its still not as loud as some older drives. All these drives are quieter than earlier generations.
While the average access times, as reported by Winbench 99, are pretty close, take a look at the CPU utilization scores. Suddenly the Seagate drive starts to look interesting -- maybe it doesnt move large blocks of data as fast as the competition, but it uses much less of the CPU in the process.
