"The petite size of the Seagate 160GB Momentus 5400.3 PATA hard drive certainly belies its amazing capacity. Its compact 2.5" form factor packs in 160GB of storage space!

That may not be a lot when compared to desktop hard drives, but those 3.5" drives are significantly larger, heavier and more power-hungry. As far as notebooks are concerned, this drive is a monster in disguise!

This amazing capacity is due to Seagate's implementation of Perpendicular Recording. By magnetizing the data bits perpendicularly to the plane of the platter, it allows a higher areal density than what was previously possible with the traditional method of longitudinal recording. The use of ST Microelectronics' Smooth Drive technology may also have allowed them to pack more bits into the limited surface area of the small platters.

Unlike most notebook drives, the Seagate 160GB Momentus 5400.3 hard drive comes with a large 8MB SDRAM buffer. Such a large buffer is usually found only in desktop drives. This will certainly help its burst performance, although we will have to see just how much in our benchmark tests. Be sure to check back soon for the full review and our benchmark results!

Incidentally, this hard drive comes with a magnificent 5-year limited warranty! While this does not guarantee that this hard drive won't quit on you in the next five years, it does show the amount of confidence Seagate has in the reliability of this model."
