Re: RAID Suggestion for webserver



With RAID5 and 4 disks... the RAID5 would not survive more than 1 disk
failing... that sort of gives me the heebie jeebies.
Thats why I thought RAID5 with 3 disks and 1 spare or RAID10.

Backups are done daily, but the data is sent to a central backup server,
so it takes a while to pull the relevent data out in case of a
restoration. So if at all possible that is to be avoided...
