ext4 - Filesystem recommendation for 5 TB file storage

I have a locally attached 5 TB RAID6 system (IBM DS3512). It will be used as a storage for large data files that are written in sequential writes, and then read back for processing. Eventually the data is deleted.




Directory traversal is not important, as we have our own indexing service.



Since this is an online system, availability and resilience from corruption is important, as is fast rebuild time.



Does XFS have particular advantages over EXT4 in this context?



Furthermore, how would I go about tuning the filesystem?



The target system runs RHEL 6.3.
