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 and edited the post afterwards (I noticed it too late). I meant, installing game data from a .iso (or folder file format) from an external HDD vs. installing game data from a .iso (or folder file format) from the PS3's HDD. Since .pkgs from the PS3's HDD install game data faster than the ones from an external HDD, it's the same thing regarding .iso (and folder file 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 (I've been told Persona 5 does) or if not running from the PS3's HDD? Sorry, but how can I see the .ird?
