This is a great product, It works like a charm, no problems at all, connect and ready to go. The capacity is massive, you can store a huge number of songs, photos, and other digital content. It is very silent, which is quite good. I am using it with a laptop running XP SP2, and so far not a problem. It is very small, smaller than WD's Passport Drive. It looks stylish, nice black finish. So the good points are: great capacity, fast connection, easy to use, no installation or separate power supply required.
Things I did not really find good: the USB cable provided is ridiculously short, I mean this is completely useless. My USB ports are close to the laptop fans, so no matter how good the cooling capacity of the drive is, it will still be positioned near the fan, getting all the hot air out of the laptop, and thus increasing its heat. This is not good, and the only solution is to get a longer USB cable.
2nd Point: the build quality seems ok, but not impressive. It does not feel very solid. The build quality in WD's Passports is better.
Anyways, this is a very good hard drive, I am happy with it, and the USB cable issue is not a big one, but would have been nicer to have it all in a perfect package. I would totally recommend this drive, definitely very portable and essential for everyone who likes to keep this files with them wherever they go.
