The Momentus 5400.4 is Seagate's second notebook hard drive to feature perpendicular magnetic recording (PMR) technology. 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.

By increasing the areal density, Seagate was able to greatly improve the transfer rate and performance of the Momentus 5400.4. Let's find out just how fast the Seagate Momentus 5400.4 goes!
