OK I just went ahead to install a second SATA hdd. Steps I took is:
Halt pfsense (I read somewhere this is the right way to shutdown)
Physically install hdd
Reboot machine and use gparted to format hdd with ext4 (is this the appropriate filesystem?)
Make sure BIOS recognise the hdd correctly
Reboot and enter GUI
I used Diagnostics SMART to retrieve below info. Looks Ok to me.
Does this mean my second hdd is ready for use within pfsense? I want to use it for caching.
