Business Disk WinMark 99

High-End Disk WinMark 99

• "The [WD Caviar] 40 BB’s WinMark scores shatter previous records…they stand in a class of their own."

• "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." 

• "Packing just two platters, the WD400BB is indeed a quiet and cool design."
