PT12 Best Ext Hard Drives

Just upgraded to PT 12, am building a dedicated machine (having issues with current mac and hd). I don't see the G-Drives on their recommended list anymore, what have you found are the best working external hard drives?

How about SSD drives?

Thanks in advance.

Will be using:

Mac Mini Running Yosemite
Digi 003 via Thunderbolt to Firewire Adapter
HD?
