Sometime ago I created post similar to this.
If I'm correct fsck hook is going to force file system check for ext4 fs
I will install manjaro on second computer.
sdd - system - btrfs (fot btrfs fsck hook in m-a is not needed [wont even work]). / and /home on the same partition
hdd - it's going to be data drive (about 800GB of pictures) - I'll go with ext4
For config like above with system on btrfs and data (symlinked to home) what is the best option? (safety of data on the first place, speed is second)
