Have a look at dedicated external journal disk performance for ext4. It actually is pretty fast, and relatively safe.

I find performance wise, a logging fs like f2fs is actually not as terrible as one would expect for most use-cases:

UUID=abc /home f2fs defaults,noatime,nodiratime,noquota,discard,nobarrier,inline_xattr,inline_data 0 2
