WinMark scores are, to put it mildly, impressive. The WD400BB's Business Disk WinMark score of 8.4 MB/sec is a full 7% higher than that of the Maxtor DiamondMax Plus 45
, itself a record-breaker. The margin in the High-End WinMark is similarly impressive... also 7%.
In fact, the WD's Business score brings it within two percent of the current leader, Quantum's SCSI Atlas 10k II. Many manufacturers (Quantum included) believe that WB99 continues to paint the most reliable picture when it comes to workstation disk performance. Assuming this were true, the WD400BB provides 98% of the performance of the Atlas 10k II in business applications.
SR readers know, of course, that we like to temper WinBench 99 results with a healthy dose of IOMeter. Let's see how WD's unit fares.
