The Seagate Momentus 7200.4 drive performed very well throughout the testing. The drive even gave the bigger brother the 3.5" Seagate 7200.11 drive a run for its money and even beating it out the majority of the time. The overall read and write speeds were the best of the comparison drives for all of the testing, reaching over 100MB a second at one point. The fact that this is a 2.5" hard drive this makes it a great contender for everything from a laptop, to a server. With desktops and servers trying to save more space, this drive makes a great candidate for any situation you need. The Seagate Momentus measures only 9mm thick so this can be placed into the thinnest notebook and even some netbooks. With this speed comes a price tag though. At $119.99 for the Seagate Momentus, it breaks down to $0.24 a gigabyte.
