Western Digital inches ever closer to IBM's pace-setting Deskstar 60GXP
in the Workstation IOMeter
index, a normalized average of light, medium, and heavy loads
. The WD1000BB's index of 164.13 trails IBM's drive by a scant 2% margin.
Differences in the File Server and Database indices are a bit more substantial, ranging from 3% - 11%. It's pretty clear that WD optimized the 1000BB's firmware for workstation-type loads.
