Hi, I have possibly messed up…

I scored a 10Tb SAS drive (Ultrastar DC HC330) and went looking for an interface card. I have ordered a 9212-4i4e, which has 4x SATA ports internal and one external SFF-8088 SAS port. I figured future drives I add were more likely to be sata than sas but my read of the manual is that the sata ports can also take SAS drives.

Trying to figure out what cables I need for SATA to SAS and got a bit lost. I then figured I could just loop the external SFF-8088 back inside the case and that looks like is really more for an external device that houses the SAS drives?

Help!
