Now it's turn for our own patterns for IOmeter, which are "closer" to users of home PCs, as well as to hard disk usage intended by the manufacturer: NearLine Storage (disk-to-disk backups, constant content and archive storage, data loss prevention and data restoration), digital video recorders, home media-servers and video editing and video storage devices. As a try-on, I will publish the results of two following patterns in two forms — in the graph form and in the form of diagrams with figures. The future will show which variant is more illustrative and faster "to strike root". :)
Ambiguous picture can be seen in the imitation of reading and writing large files (like mp3, video, large photos, etc): the old 180GXP is obviously leading in reading. It is followed on the heels by both 7K250 models, which are noticeably faster than the 7K400 models. But writing offers a completely different picture — 7K250 hard disks become the leaders (the SATA model outscores the UATA model due to its buffer), while 7K400 hard disks, though noticeably behind the leaders, are positively bronze winners, having outscored the 180GXP. But if we average the results, the old Vancouver 2 still manages to worm its way between the two "Kurofunes". The "quiet" model is certainly outscored by the "sterling" one. But while this difference is considerable in reading, it's negligible in writing (remember the excellent results in reading and writing access times).
Both the japanese and the americans demonstrate almost complete "unanimity" in imitating reading and writing small files, but they show a wide spread of "opinions" in writing. 7K250 series hard disks are again the leaders here, and the quiet modification of 7K400 SATA model (complete correlation to the write access time test, though the block sizes in these tests are noticeably different) "bursts" (that's definitely the right word for it) into the third place. On the average, 7K400 series models look well, having outscored the 180GXP, but still inferior to their preceding 7K250 models.
