The difference in access time
between the Cheetah 36LP
and the Cheetah 73 is greater than the specs imply. The 36LP's seek time
is rated a 5.2 milliseconds vs. 5.6 for the 73, a difference of 0.4 milliseconds. Interestingly, however, WinBench 99 clocks the 36LP's access time at 0.7 milliseconds over the 73.
It should also be noted that while the 36LP and 73 share the same physical platters, the 73's transfer rates in both the outermost and innermost zones clock-in (albeit negligibly) slower.
