Hi
I always used SMB, but updating to OMV 4, speed became a problem.
I now "found out" that one can use Apple Filing not only for Time Machine, but also for normal shares ... likely no surprise for many 
Until now, it is fast and reliable
My question:
Are there any disadvantage for using AFP over SMB (if only Apple devices are used in home network) that I should consider?
Thank you!
Regards
Nico
