Recently LaCie released its 1TB, 3.5? external hard drive. Although the hard drive is quite bigger than the previous model, most its spacious and rugged. The rubber bumpers all around the drive help absorb the shocks if you drop it.
The hard drive is available for$140 and offers a max read and write speed of 30MB/s. However that speed drops to almost half if you tranfer small files and mix data i.e. 15 MB/s. Still this transfer rate is good for external and rugged hard drive.
As said, this external drive goes well with your netbook. Netbook are designed for portability and offer very little storage space. But sometimes you need your movies and stuff with you while traveling, so you need a portable hard drive. And being rugged makes it more ideal for portability.
