The newer Atlas 10k II does not fare as well as our original sample in
IOMeter. It starts with the new unit lagging the old by about 2% in a
Linear Workstation scenario... this gap widens to 5% and 6% respectively under
Moderate and
Heavy loads.
Seagate's drive, on the other hand, exhibits some slight improvements across the board. The new drive improves over the original by a tiny 1% in the Linear Workstation load. This improvement, however, peaks to a 6% gain under Heavy loads.
These reversals lead to an interesting change in the Cheetah vs. Atlas story as told by IOMeter. Judged with our original units, the Atlas 10k II possessed a marginal advantage over the Cheetah 36LP. Now things are reversed. Due to its superior seek time, the Atlas retains a lead of 4% under a Linear load. In every other case, however, the Cheetah leads. Very Light, Light, and Moderate loads peg the Cheetah 5% ahead of the Quantum. The margin increases to a significant 10% under a heavy load.
Conclusion...
