Yea thats the downside to RAID 0. If one dies, the other goes down with it. But I've seen alot of people here at TF, with RAID 0 setups. I would do it, if I had the extra drive. I'm assuming you're getting either a Western Digital or Seagate, which are both very reliable companies. Also don't forget to backup your data, just in case something does go wrong...you never know.
