AX4 for Disk type backups

I have to configure one AX4 with 4X1 TB SATA drives + 1 HotSpare. This is going to be used as a backup device only. I am new to hardware and would like to know your views on which RAID level would be ideal and should I configure one single large LUN or multiple smaller ones for optimum performance?

depend on ur environment
Use a RAID 3 group with a single-task application that uses large I/O transfers.

i think its better to use " multiple smaller luns than one large lun"

I am going to use EMC Retrospect for Backups and that too from desktops, I don't think we have large I/O on a desktop backup solution. Let me check.
