And now — newer complex performance tests in PCMakr04 and C'T H2BenchW benchmarks. They both "play back" prerecorded hard disk activity tracks in corresponding applications and measure the completion speed of each track, and then they average the results.
The disk test in popular Futuremark PCMark04 is often used by common users for express-evaluation, though it's not free from shortcomings. We provide its results not for the sake of an objective picture but to let our readers get their bearings on their own results. All japanese models provide very similar results and offer the following picture: The UATA novice is winning with a small breakaway, it's followed by the old SATA model. "Quiet" hard disks are slightly outscored by noisy ones.
Similar "track" test H2benchW is more sensitive to model differences: the senior 7K250 SATA model is again an obvious leader, as in WinBench 99 tests, both 7K400 models are practically on a par (and the quiet seek mode is not an obstacle). The outsiders are natural (the WinBench 99 situation is repeated), though they are outscored by the leaders by 30% or even more!
The outsider in working with Adobe Photoshop temp file is the oldest hard disk — even its 8 MB buffer was of no help against the HDS722516VLAT20. The leaders in this test are the new 7K400 hard disks (including the option with the quiet seek mode). Perhaps, larger capacity allows them to outscore the senior 7K250 due to smaller range of head movements during the test (closer placement of necessary sectors and tracks).
