USB 3.0/3.1 Generation 1.
Both, the standard PS4 and the PS4 Pro are packed with USB 3.0/3.1 ports.
The PS4 USB 3.0 has a SuperSpeed transfer rate of 5 Gbit/s which can transfer about 625mb/s.

**************

PS4 Pro supports SATA III

With SATA III support, the PlayStation 4 Pro's hard drive storage can hit read and write speeds of up to 6Gb/s, or 600MB per second. (in theory & this matches the USB 3.0 transfer rate, so.....the system architect decided to...)

The PS4/Pro internal SATA bridge is connected through the USB chipset.
