The one warning I;'ll gibe- if your PS4's power goes off while connected to the hard drive, or if the hard drive is disconnected while the PS4 is on- it could corrupt. I once left my PS4 on low power mode, and the power went out at my house. I had to reinstall EVERYTHING on the External. Also, I've had to hard power down my PS4 when it froze up a couple times, and accidently bumped the cord for the external once- Didn't lose anything those times, but the hard drive had to "repair" each time. Make sure it's in a stable spot where it won't get bumped, and try not to leave your PS4 in low poower mode.
