From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Ext4 is old, but fast and very robust. You won't loose data or corrupt the filesystem if your system looses power. It can even survive partial wipes, if you accidentally overwrite the first few megs of you drive with a messed up dd, nearly all your data will be recoverable, including filenames and directory structure.
It doesn't have very fancy features, but it is the best tested and most robust option available. (also the fastest due to its simplicity)
Btrfs has things like copy on write files that can protect you from an accidental rm, but this won't save you from drive failures, so you still need backups for important data.
Some secondary storage devices ignore standards and outright lie about sectors being successfully written when they are actually scheduled to be written out of order. This causes obvious problems when power failure prevents the true writes from completing. Nothing can be guaranteed for such drives.
