I am currently configuring RAID 10 (first time doing RAID ever) for a server at work. In the Configuration Utility. I am given the option of either span 2 or span 4. Having never done this before, I was curious if someone could tell me the pros and cons of for each span? Thanks

The server is a Poweredge r620 with a PERC H710 mini (Security Capable) RAID controller. I have 8 600GB hard drives. I am creating this server as a network storage drive. I have SQL server historian database whose 1TB storage filled up and after 5 years of logging data.
