I've been extremely happy with PortApps. A couple days ago I bought a 4 GB SanDisk as a backup and that was my (accidental) introduction to U3! I'm running both PortApps and U3 on the drive now.
I like the U3 autorun feature. But my main interest with flash drives is Security. From what I've read, U3's password protection is not really protection at all. I need a drive that I don't lose sleep over in case it gets lost or stolen. The apps are replaceable, but the data isn't.
So my questions are: Is one system (PortApps or U3) inherently better than the other in terms of data security? Is it sufficient to use strong encryption of the data folder in either case? And is there a recommended security app for data encryption?
Thanks is advance.
