WinBench 99 clocks the 40GV at 15ms, definitely much better than that of both the U5 and lct20. Subtracting 5.6ms (the rotational latency of all 5400rpm drives) yields a measured seek time of 9.4milliseconds. Big Blue's specs are right on the money, something not too common these days. Being a 20GB/platter unit, we expected the Deskstar 40GV's STRs (sequential transfer rates) to be nothing short of stellar. The outer-zone STR is 31.2MB/s, virtually a tie with the Seagate U5. The inner-zone STR is quite another matter however, with the 40GV curiously lagging behind, coming out just slightly ahead of the Seagate U10.
Clearly, the fight here is between the Deskstar 40GV and the U5. Let's see how to these scores translate into higher-level performance.
