Speed

I haven't had them fail yet, but they are horribly slow. There is about 4GB of high speed caching, then write speeds drop to a little over 10MB/S. They are great for keeping small files at hand and moving them around, but if you plan on moving large files around with them don't waste your money.

Quick write speed

Reliability

I bought two of these. The first one started getting read and write errors after about 3 weeks. Thankfully ME was able to refund it for me even though my store return window had just passed. The second one failed about 9 months after that with the exact same symptoms, and is no longer readable as a drive. The usage for both drives was very light as far as the writing, and moderate as far as the reading. I'm going to buy some smaller capacity ones and get the warranty on them.

I left this USB stick plugged in for a week, so I guess it can't handle that.
