Hello, We purchased Dell 3TB drives and installed them in PE R710 with PERC 6i. Prior to purchasing the drives, we checked online and it said that it is supported.  We upgraded the firmware on it to the latest version.  BIOS is up-to-date as well. Firmware Version 6.3.3.0002 Driver Version 6.600.21.08 Storport Driver Version 6.3.9600.17031 This is the physical disk information below.
