Hey Tim! I was just at Ignition Alley today, in the loud room, working on this post.<p>I have lots of backups in place - files I don't touch in more than a week get moved to S3, as well as Time Machine and a working clone of the drive made every week.<p>That being said, RAID 0 gives me more space and is faster for reads and writes (that are larger than the block size that is)! Risky indeed though. I touched up on this aspect at the end of the article, and also noted that this setup will only exist on my MBP for 9 mons or so, at which point I'll upgrade to some faster SSDs.
