Seagate’s 2.5″ 160GB Notebook Drive Largest Available


Seagate today announced the newest in its line of laptop hard drives with the Momentus 5400.3 2.5″ hard drive, which looks to increase the number of drives the company will offer with perpendicular recording capabilities.

Perpendicular refers to how bits are arranged on the recording surface, standing them on end rather than along the surface in familiar configurations. This rearrangement lets more bits pass over the drive head in less time, increasing efficiency and lowering power consumption.

Seagate also seems to be betting that more users will want higher drive capacity in their notebooks. This makes sense in a world where what, and how much we store on computers grows by the day. Of course, raising storage amounts also narrows the gap between desktops and notebooks, an indication that some may choose to forego the former. Showing a commitment not only to hard drives in notebooks but also high use or rough environment implementations, the Momentus family is designed to withstand 350 Gs of operating shock and 900 G’s when not operating.

By announcing the Momentus drive in the 2.5 inch format, Seagate seems to be saying that the notebook market is expected to grow with the needs of its user base. But it is not ignoring the rest of the market. Momentus drives and its perpendicular recording method will be extended to all available spin speeds, capacities, ATA formats and size formats. The Momentus 5400.3 currently uses Ultra ATA 100 connectivity.
