Linux

I've used the old 'ntfs' driver that supposedly can't write to... write files ranging from 100,000+ small files in folders to individual 200+ GiB files on NTFS partitions. It works pretty well and I have used it for video editing (few huge files), software development (many tiny files), Unreal Engine + Unity, Linux Gaming w/Steam and more. Rock solid.

After hearing that the 'ntfs' driver is supposed to be read-only, I switched to 'ntfs3' instead of using 'ntfs3g' (~~same code, but compiled into the kernel instead of running outside via 'fuse'~~). From that point onwards, I've had major file system corruption nearly every day:

• Copying files into folders suddenly made 90% of other files in the folder disappear. Could be fixed by copying about 1000 random files into the folder and deleting them, then the missing files would come back into existence.
• Files that suddenly go bad. Can't be written to, moved or anything. Often happened in software development when compiling my project, suddenly the intermediate build directory was bust due to undeletable files.
• Folders that suddenly contain themselves or one of their parent folders as sub-folders.
• Folders that contain a specific file infinity times. This way, I found out that even a harmless file manager like KDE's Dolphin can become a behemoth that eats 100+ GiB of RAM and keeps trying to read the "list" of files in a directory without limit.

Personally, I'll never use 'ntfs3' for serious work again. But 'ntfs3g' is generally considered very stable, maybe my issues are specific to 'ntfs3' or my RAID setup (weird nested mdraid thanks to Intel) is to blame.

My final 'fix' was to move everything to ext4 and buy Paragon's $20 ext4 drivers for the dual boot Windows install. It's only seeing any use once every 2 months. Sadly, these drivers are case sensitive even on Windows, rendering Bethesda games unplayable when installed on those partitions, for example.
