The 32GB version is better than the 16GB but not by much. At 5 you can't expect much, and this product is not too bad if you take the price into account. The main complaint is the writing speed and the fact that it will constantly pause when writing any files. Not too much of a problem if you just want long term storage. But if you are going too copy files to this pen on a regular basis, walk away.
I would not use these for constant backing up and file changes because they simply have poor file writing capabilities. Read speed is not to bad and is faster than USB 2.
In short, both the 16GB and the 32GB are ok for if you want store stuff long term but not recommended for day to day file transfer usage.
