The WinBench 99 Disk WinMark
scores between the WD405AA and the Maxtor DiamondMax 60
are much closer than one would guess given the drives' low-level perfomance. WD's offering lags Maxtor's drive by a mere 1% in the Business Disk WinMark 99. The High-End Disk WinMark is even closer, positing a dead-heat between the two drives.
Where WinBench fails to detect a difference, IOMeter might. Shall we?
