RAID 0 risky ?

Is RAID 0 that risky anymore for data storage (IMAP mail files) ?

I figure that under normal wear and tear a drive should last about 5 years.

Does this sound right ?

I have 3 IBM SCSI 18GB drives. 

With RAID 0, I get 51.5GB of storage space. 
With RAID 5, I only get 37 GB of space with 20% wasted overhead. 

RAID 0 and RAID 1 are less work for the disk volume than RAID 5.

So in an ideal world, volumes with RAID 0 or RAID 1 will last longer than 
volumes in RAID 5.

Thus, it would be less risk to use RAID 0 or better RAID 1 than RAID 5.
