Rating : - Nice little package
The reason why I got this item was because I needed to backup my PS3 data, since I'm upgrading the hard drive on the system. As soon as I opened it, I just plugged it in and that's all. No need to install software or anything. I was surprised at how small and light this drive is and it was nice to have something so simple to use. Perfect for what I needed it. This thing took about 30min to copy about 20G of data which, and I'll be honest, I'm not sure if its good or bad, but there you go.
