NSA 325 write performance explained


 

Just found out some more about the benchmark-winning write performance. I should have noticed this earlier but this was what check_mk picked up at inventory time:

(‘nsa’, ‘mounts’, ‘/i-data/ef9c2dc9’, [‘barrier=0’, ‘data=writeback’, ‘noatime’, ‘rw’, ‘usrquota’]),

 

Turning off barriers and setting writeback is _questionable_. On the other hand, I’m just storing backups on it in a raid0. Just, makes me wonder how other owners would rate those settings if they knew…
