I tried copying game data when we were replacing our PS4 hard drive, but it just caused a lot of problems (with games having to “verify” the installation when launched, which was a very lengthy process, probably longer than just re-downloading it would have been; I don’t know what it was actually doing). We were able to preserve save data, though.
For me, this was because the PS4 uses USB 2.0 that caps out at 480 Mbps. It was basically doing checksums of the backup files vs the restored and it just took time, even when the backups I had it running on were a sata SSD.
