If you demand to be mobile and still have the hard drive space you need, then you should look at the Seagate Momentus 5400.3. It’s the first mobile drive to be equipped with a full 160GB of disk space, and still retains great speed.
The drive I will be comparing to in benchmarks is my Hitachi Travelstar, which is a 7200RPM 60GB drive.
The hard drive is in no real packaging, just an anti-static bag. These hard drives are so light, that at first I thought they forgot to put it in the box.
Here’s a comparison in size of the HDD to a music CD.
