just added a second cheap NVMe drive to my system and am in the process of moving my games folder to it. the folder has a coupla prefixes and individual game folders. presently it's ext4, my boot drive is btrfs and encrypted LVM, the ext4 drive gets mounted to ~/Games via fstab.

is there a better combination? like, would I benefit from CoW or compression for this use case? or even going with ntfs?

edit: went with btrfs. super easy to convert from ext4, just unmount the 2nd drive, btrfs-convert and change the UUID in fstab. also added the compress=zstd:1 option. looks like everything is working thus far.
