If this is a server, you would use SSD or SAS but never SATA drives. I can't stress this enough. Tech support does AC, they don't set up servers. Sandeep does that.
SATA is fine as long as you use one of those enterprise SATA drives like the WD RE4. Do not use something like a WD Black Drive as it doesn't have things like TLER which is a necessity for RAID controllers. The difference between SAS and SATA is diminishing. I use enterprise SATA drives all the time.
