You can compare their characteristics with those of some mobile 5K and 4K drives in this summary table.įirst of all, while top 100GB Travelstar 7K100 series models offer the data density of 81 Gbit per square inch, cheaper models from this series (80GB and 60GB) offer lesser data density - 66 Gbit per square inch. The key technical characteristics of these drives in comparison with predecessors and competitors are published in Table 1.

Hard drives from this series have become the second 2.5" drives after Hitachi Travelstar 7K60 from this manufacturer with the spindle rotational speed of 7200rpm. Travelstar 7K100: Design and Characteristics So it comes close to its desktop counterparts. For the first time in the history of 2.5" drives for notebooks (as the magnificent Savvio 10K.1 is of the different size) it managed to outstep 50MB/s for maximum linear transfer rate. Perhaps, the first real applicant to the conquering role will be the top model in the Hitachi Travelstar 7K100 series.

Nevertheless, we can only welcome the fact that manufacturers strive to reach the desktop performance level in their notebook drives. And the average access time in these mobile drives (about 15ms) couldn't compare with typical 13ms for desktop 7K drives, despite a noticeably shorter linear travel and weight of the actuator arm with heads (however, hardly lower angular travel, but smaller surface area/power of VCM magnets). And the first mobile 7K drives could boast only of 40MB/s odd.

But this situation has been full of conventions up to now, as the maximum linear read rate in desktop 7K drives has reached 60 MB/s several years ago (50MB were outstepped long ago). :)Ģ.5" mobile drives with the spindle rotational speed of 7200rpm were initially designed to raise HDD performance in notebooks to the desktop level. When they actually appear on the market, the 7K100 model will be no more unique.

However, Seagate has recently announced Momentus 7200.2. Travelstar 7K100 drives are the only mobile 7K drives of the second generation on the market so far.

They also inherited their codename: the 7K60 model was called Moraga-C, and the 7K100 got the name Moraga Plus C. Having appeared on the market at the same time as Momentus 7200.1, the 7K100 drives inherited and developed the nearly 2-year Hitachi traditions of manufacturing hard drives of this class, that started from Travelstar 7K60.
