Query: Slow

I had the same problem with the write protect error that was mentioned by the other reviewers. After loading about 15gb onto the device it froze and game me the error. Centon sent me a replacement with no problem and the new one works fine. They seem to have a reliability problem with this product, but at least their customer service is good. However, this flash drive is very slow. It takes about 22 minutes to transfer a 6gb directory (720 music files), versus 16 minutes for my 16gb Corsair flash drive. Also, I paid $50 for this product, but the price seems to be higher now. I would stick with the 16gb Corsair, and if you really need this much storage you are probably better off with a portable hard drive which is much faster and probably more reliable.
