Thanks for the reply. According to the RAID table I posted it looks like RAID 0+1 is a lot more vulnerable than RAID 10. However, I have had drives 2&3 fail in a 4 disk RAID 10 on a modular server and the Array was OK. I would expect that 1&4 could possibly fail as well. It would be nice if I could get something official from Intel that would identify which two drives could fail without the Array going down.
Thanks,
Shane
