Dears,

Which RAID system do you recommend for a file server with following criteria:

- stored documentation, NOT database. read more frequent.
- failover is crucial.
- No. of disks 10 * 300 GB

I won't used Mirror due to amount of disk uses.

Go RAID6.  Remember RAID5 only protects against a single HDD failure, with no bad blocks on surviving drives.  So not only are you exposed to 100% data loss during the time it takes to rebuild a RAID5, but also you are exposed to partial data loss if you have any unreadable blocks either before the failure, or during the rebuild.

Performance hit on writes between RAID6 & RAID5 is nominal.
So do you want to be able to get some sleep in event of a drive failure? If so, go RAID6.

RAID-6 is always a better choice than RAID-5, since it provides an additional level of redundancy that allows a rebuild to complete even if a 2nd drive fails during the rebuild.
