In general, Raid 0 (and 5) are highly overrated and only will 
increase performance in heavily loaded server environments.  Raid 0 
doubles the probability of failure, since the failure of one disk 
makes the data on both drives unusable. See this:

Raid 1 is good for reliability and has minimal impact on 
performance.  Since, as Kit pointed out, Stata hardly ever hits your 
disks, it will not matter.  The same is not true for SAS, SPSS and 
other disk-based systems.

Best,

Steve
