jZnat asks: "I own hundreds of gigabytes of binary data, usually backed up from other mediums such as CDs and DVDs. However, I cannot figure out which filesystem would be best for storing all this reliably. What I'm looking for is a WORM-optimized FS that also has good journaling methods to prevent data loss due to some natural disaster while data is being shifted around. Trying something new for once, I tried using SGI's XFS due to its promising details, but I was met with countless IO errors after trying to write large amounts of data to it. I feel that Ext3 is not optimal for this; ReiserFS is too slow when it comes to reading large data files; and Reiser4 isn't mature enough to entrust my digital assets to. What filesystem would be most appropriate for these needs?"
