You could always copy your flash drive to an internal drive or do a full install. The point suggested is to use the flash drive instead of downloading game media, which would be a fine solution.That's not the point lol. its preference. No way in hell I wanna deal with different flash drives for each game. Much easier to miss place and damage.
Plus to have flash drives that will be able to keep up with speed requirements will only add to more cost and might never be as fast as internal IO.
Yea I do remember having to wait for levels to load off disks and glad your disks work from the 90s. I had so many I had to rub and clean to make work its crazy lol.
