@windg I don't think so. At least I didn't do anything more with my ext4 usb ssd. Here's the relevant part of my fstab:

PARTUUID=2c31bca2-b1f4-4466-ab20-3a347852ba2c /media/usb0 ext4 defaults,noatime 0 1 /media/usb0/roms /home/pi/RetroPie/roms none bind,bg 0 0

Some notes:

I generally prefer UUIDs over device names (e.g. /dev/sda1) in the case that the latter is changed by the system someday for reasonsâ„¢ (or perfidy đŸ˜› ). I'm using two mounts, because my drive has a roms directory that I mount in ~/RetroPie/roms (with the option bind that mounts directories in directories) after mounting the drive itself in /media/usb0. I did that to be able to have other directories on the drive as well, since its 250 GB exeed the size of my rom collection by far. The option bg should tell the system to retry the second mount in the background, in case the first mount isn't completed yet. But I'm not sure this option is still viable in the current version of mount/fstab.
