Following the PS4 External HDD Listing and PS4 Loading Time Comparisons, hard disk drive manufacturer Seagate is now offering a 2.5" 2TB capacity Seagate Game Drive for PlayStation 4 that meets the USB 3.0 HDD requirements for those on PS4 4.50+ Firmware. 
Beginning this month at select retail stores the 2TB (Model STGD2000400) Seagate Game Drive for PS4 will be available at $89.99, which isn't really a great deal in comparison to Seagate's standard USB 3.0 drives that are also compatible.
