"Don't buy this item, very unreliable"
I bought this drive to take some of the clutter off my computer. After I completely transfered over 11 gigs of pictures from my study abroad in Ecuador, the drive crashed... For no reason, no damage occurred and I didn't use it improperly. There is no customer support for recovery of data, and even an outside technician failed to recover any of my pictures. I wouldn't ever recommend this to anyone, especially with the lack of customer support. And due to the fact that they are completely unreliable. You shouldn't need to back-up your back-up.

"Gotta love USB storage"
So far this has been a great little unit for drag and drop file storage. I mainly use this little guy as mp3 storage that I carry around with me. I love not having to plug in a power adapter.

Transfer can be a little slow, given the slow rpm of the drive its not surprising though. It's nothing I can't deal with though.

"It worked great for a while"
I loved this little thing in the months after I bought it... I would hook it up to my PC and save things on it, and then when I needed to take my laptop somewhere, I could just take it with me and have everything I needed. It doesn't need external power. HOWEVER, something went wrong with it before I had even had it a year. I plug it in and the computer won't even recoginize it. A friend said that it might be a power issue, so I bought an external power adapter, and plugged it in, and the thing shorted out my laptop for a while... talk about giving me a heart attack. Luckily the laptop started working after a couple minutes. I know the hard drive part is okay, as I was able to see some files before it shorted out the laptop... so I'm going to tear it apart and plug the hard drive into the computer with an adapter to at least get the data off. I emailed the support on their website and got nothing back.
