Hard disks for mobile computers always was inferior to their desktop fellows in term of rotation speed - such are the power energy requirements , which have enormous value with work in notebook. The mobile hard disks are not also large in capacity : only few month ago with the passage to technology perpendicular record appeared hard disk of form factor 2.5 inch with volume 120-160 Gb. In a word, its necessary to sacrifice for the compact sizes and low energy consumption.
Associates recalled that yesterday seagate company announced the series of hard disks momentus 7200.2, which propose high speeds and volumes in compact form factor 2.5. These hard disks have rotation speed of 7200 r/min, support interface SATA-150, they are equipped with buffer with volume 8 mb. or 16 mb. Models number consists in hard drive by volume : 80, 100, 120 and 160 Gb. These hard disks use just two magnetic disk with technology perpendicular record.
Another important special feature of hard disks seagate momentus 7200.2 : the possibility of equipment with the sensor of free drop, which allow to prevent failure of system disk as a result drop in notebook. As soon as sensor intersects acceleration, equal or exceeds 9,8 meters per second in second, heads they are transferred in cover position, decreasing thus the risk of the damage for heads and magnetic disk.
In the non-operating state the hard disks of this series are capable of maintaining loads up to 900 G, in operating state they maintain loads up to 250-350 G. the energy consumption of hard disks momentus 7200.2 does not exceed 2.1 W. The deliveries of hard disks from this series already began, prices are not defined. Related Products :
