I have encrypted the drive with TrueCrypt and use it as a safe transportable "hard disk" on my laptop. After use, I prefer it off and on the laptop itself are confidential Daten.Aufgrund the size you can carry him for almost the purse. The drive disappears when plugging almost completely in the laptop, so the risk is very low abort. There schellere USB stick but he is clearly noticeable faster than USB 2 stick. He is warm but not too warm in lively use. I can really recommend this stick.
