No. RAID doesn`t stress HDDs.

RAID-0 uses more drives to store the same amount of data without redundancy, so theoretically there`s an increased risk of data loss at the same HDD failure rate.

I also have suffered minimal HDD failure over the years. I attribute it with taking extra care in mounting. I use high-quality cases with rubber grommets. I space the HDDs out so that no HDDs are adjacent to each other. I always assure a good supply of cooling air around them.

I used a set of four IBM Deathstar 75GXPs in RAID-0 for over five years without an issue, migrating the array between three different motherboards with three different Highpoint RAID controllers.

No, RAID doesn`t endanger data, but it doesn`t really protect it either. It is not a reliable means of data security. It is a convenient way to recover from single-drive (or in some cases two drive) failure without downtime. It doesn`t protect against malware, fire, flood, theft, operator error or any of the other ways that data is lost simultaneously on mirrored HDDs.

Real data security comes from multiple offsite backups.
