raid10

I'm building a server with 12 x 3TB disks to use daily backups. I'm thinking to use RAID50 to get a good 27TB usable space.

The disks will be used brutally to backup 9 servers with 1.5TB of data once a day. I'll keep the backups for 2 days. So for each server I'll have 3TB of separate partitions.

Do you think this kind of huge backups would stress the disks too much and make them fail?

Should I better go with RAID10?
