If your passphrase is 25 or more fairly unstructured characters, then it should be reasonably secure for a decade or two at least. If your passphrase is a lyric from a song or a line from a book, or really any phrase that has ever been written in a public context before, then it's not very secure. If your passphrase is ALMOST like one of those things, but was created by someone who thought they were super clever for substituting some letters for similar-looking numbers or symbols, then it is STILL not very secure (every password cracking program tries all these cute substitutions and more). If your passphrase is, say, 15 characters or less, then you might have cause to sweat a little.

Here's an example of a pretty damn good passphrase:

another gone change use wonder someone hair cold open best any behind

Always go for longer rather than more complex, if you have to choose. And take the time to memorize it for real, every single day for a week. Or write it down somewhere extremely safe.

You may also be interested in DiceWare for creating very secure passphrases.

Ubuntu? Careful you might have to drop out of college if you get Ubuntu.

As long as your computer is powered off, both are extremely secure and i would say no one except maybe the highest levels of the NSA would have any chance of getting data from them.

just make sure you use a long and random pass phrase and power down your computer when you're not using it.
