The Quantum Fireball Plus LM's
blistering access time (about the lowest we've ever measured in an ATA
drive) gives it an advantage in a Linear Load Workstation IOMeter
scenario. The Deskstar 75GXP trails the leader by about 7%. This gap shrinks to 6% in Very Light
loads, a load reached while starting up such common applications as Windows Notepad or Calculator.
It's in the more meaty Light, Moderate, and Heavy loads that the 75GXP manages to flex its muscles. In these cases, the Deskstar virtually matches the Fireball in performance, lagging by insigificant margins of less than 2%.
As an aside, it's interesting to note that while the ever popular Maxtor DiamondMax Plus 40 manages to keep up with the competition quite well in WinBench 99, offerings from IBM and Quantum hit the next level of IOMeter performance.
