Default Hitachi Deskstar 7K1000 Hard Drive Review

They accelerated the electronics with the release of the T7K250 and then they introduced a 16MB buffer in the 7K500. These HDDs were not a total success as they didnít always show the expected performance benefits, but those 16 megabytes of memory are put to better use in the next generation of HDD electronics, in the T7K500. This somehow affected NCQ support, particularly when it comes to processing two competing read threads, and the copying of large files became somewhat worse, too. The T7K1000 features certain improvements in the firmware and is equipped with 32MB of memory, but still performs oddly with NCQ.<br><br>

Otherwise, the newest HDD from Hitachi is almost perfect. It offers a record-breaking storage capacity, an extremely high sequential speed, an enlarged buffer for more performance, and fast processing of multiple data threads. As a result, it performs superbly in all our benchmarks except for IOMeterís server patterns, but for server applications Hitachi offers the Ultrastar A7K1000. This even gave some hardware reviewers the cause for pitting the Deskstar 7K1000 against the WD1500 aka Raptor II, although the two belong to absolutely different categories. We hope the minor drawbacks of the Deskstar 7K1000 revealed in our tests will help Hitachiís engineers and programmers to go on improving their products even more.
