Seagate Momentus 7200.4 500GB SATA 2.5 Review

Price: $119.99


It truly amazes me on the capacity and speed that hard drives have evolved into over the years. I remember not so long ago the large 3.5" drives with the IDE cables that took up so much room in the case. Let alone the limitation on only four IDE devices allowable counting your optical drives unless you had a plug-in card for more. Now look we have Serial ATA devices with faster speeds and smaller 2.5" drives that are as good or better than the older generation of hard drives. One new drive we are going to be taking a look at today is the Seagate Mometus ST9500420AS 500GB drive. This drive has speed and power packed into a 2.5" form factor with a 9mm height. This size makes it possible to have mounted in either your large computer desktop case or a notebook for screaming performance. Unlike the majority of 2.5" hard drives The Momentus 500GB is a 7200 RPM hard drive and has a 16MB cache. The interface is SATA 3.0Gb/s and has an average latency of 4.17 msec. Seagate states this drive to have a 11.0 ms Random Seek Time and a 13.0 ms Random Write Time, so I am curious on the performance of this baby.


Closer Look:

The Seagate Momentus 500GB drive came to me packaged OEM style sealed in an anti-static bag. This drive is very small and should be handled with care jsut as you would with any other hard drive. This particular drive is has a capacity of 500GB which equates to 465.76GB usable when formatted. The Momentus has a 16MB cache and a spindle speed of 7200RPM for faster speed and performance. It measures 9mm high so you would have no problems using this high performance drive in laptops, desktops or even servers which use the smaller drives to increase server capacity. The interface for the Seagate Momentus 7200.4 is SATA 3.0Gb/s for fast transfer speeds and performance.




Now that we have the drive out of the package let's plug her in and let her loose.
