The way you phrased it makes it sound as if RAID 0 will make hard drives die faster.
The failure rate isn't any higher than a single disk, but in the case of RAID 0, the chance of complete data loss is doubled over a single disk, because there is no redundancy and RAID 0 requires more than one hard drive. You can also think of it in another way - the more disks you add to an array, the higher the chance that one of those disks will fail. In the case of RAID 0, if you have five disks, then the chance of one of those five failing and losing all data is five times higher than two disks.
All I'm saying is if you have two 1 TB drives it's best to have them in some kind of redundant setup to save data. If you happen to lose a TB drive, a RAID 1 setup would save all of your data.
