that's installing directly to the external hdd, but doing that requires the drive to be in fat32 format. I don't think that's what you meant. sorry to have confused you.
No, sorry, it was my fault since I made a typo that confused you (I noticed it too late) and so I edited the post next. I meant, installing game data from an ISO or folder format game from an external HDD vs. installing game data from an ISO or folder format game from the PS3. Since PKGs on the PS3 install game data faster than the ones on an external HDD, it's the same thing regarding ISO and folder format games.
ISO has about 99% compatibility. some games have issues if just in jb format. you can tell which files are missing by looking at the ird. if you have any psarc files that have been extracted, there will be a folder in there named after the psarc.
And are there games which have issues in ISO format (I've read Persona 5 does) or if not running from the PS3? Sorry, but how can I see the IRD?
