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
