Over the last year the Serial ATA interface has gone from obscurity to
become the technology of choice for performance PCs. Now with the
Momentus 5400.2, Seagate brings the high performance of SATA to your
laptop. Momentus is the industry's first notebook hard
drive to combine a high-performance 5,400-rpm spindle speed with the low
battery-consumption of a traditional 4200-rpm notebook hard drive, so
customers no longer have to choose between performance and mobility.
Seagate's patented SoftSonic fluid dynamic motor and new QuietStep ramp
load technology make Momentus one of the quietest, most rugged notebook
hard drives available. Just how well does SATA perform in the 2.5" arena? Lets find
out.

Don't let the size of this little beauty
fool you, this drive is tough. The Momentus 5400.2 is designed to take
the shock of 250 Gs, let me see the rest of your laptop take that!

The Seagate design is pretty standard
with little to catch the eye on the outside. But this simple efficient
design has helped to make Seagate one of the top hard drive
manufacturers in the world.

Here you can see the SATA
interface plugs. No adaptors needed for a typical SATA install. This
SATA interface is capable of transfer speeds up to 1.5 GB a second.
