IOMeter more accurately reflects a drive's performance in a server environment, ie. lots of incurred disk access (whether from working with a large data set or a lack of RAM is another question).
Here, we see a performance trend similar to that of the Caviar WD1000BB. The WD1200BB leads all drives in all access patterns under a Linear load, with slight improvements over the WD1000BB. Both Caviars lag the Deskstar 60GXP by an average of around 9% under heavier loads, with the performance disparity shrinking in the Workstation access pattern and being virtually non-existant in the Video Workstation access pattern. All in all, a very strong IOMeter showing. We can only speculate that the Caviar's firmware has been optimized for workstation / NLE applications.
