Seagate Momentus 5400.3 160GB Mobile HDD

If you are a laptop user, you have had a constant problem. The lack of hard drive space. When I first purchased my Dell Inspiron in the summer of 2004, it included a very large 60GB hard drive. At that time, 80GB was the top hard drive available in a consumer laptop, but even that can get used up quickly. With all the MP3’s, video files and games we play, we can run out of hard drive space very quickly. Matters are even worse if you use your notebook as your primary PC.

There are a couple things that make the 5400.3 not so ordinary. Despite it’s small frame, it packs a huge 160GB store space. It also makes use of the perpendicular magnetic recording technique to make this possible. The Momentus 5400.3 comes in 6 different sizes, but the specs are virtually the same except for the discs/heads.
