Hi, I have a fedora22 system and would like to build a backup server. I have four 3TB SATA disks and would like to build a RAID5 array. I understand rebuild times can be extensive, possibility creating a scenario where another disk fails during that rebuild time, but I'm not sure I want to lose the extra space with creating a RAID6 array. I believe RAID5 also has faster write speeds? Is a 9TB RAID5 partition too risky in terms of rebuild time? What's the preferred filesystem for a backup server these days? Should I use XFS or ext4?
