No need to transfer anything, the speed makes no difference, I don't even notice that the hard drive is plugged in.

This external hard drive is compatible with the PS5. It can store PS5 games, but these must be transferred to the PS5's internal drive in order to be played. PS4 games, on the other hand, can be played directly from the external hard drive. The drive is powered via the USB port and uses the USB 3.2 interface, which is compatible with the requirements of the PS5.

Yes, you can move videos and screenshots to the external hard drive. The hard drive serves as extended storage for your PlayStation, so you can save not only games but also other files such as videos and screenshots on it. However, PS5 games can only be played on the internal SSD, while PS4 games can be launched directly from the external hard drive.

Hello Yes you can also back up games to it and PS4 games can even be played directly from the hard drive without having to load them onto the console. Only the PS5 games have to be downloaded first and then you can play them. I did it with my PS5 so that I have all PS4 games on the hard drive and the PS5 games are stored on an internal SSD hard drive. Greetings

Yes, the hard drive is compatible with both PS4 and PS5.
